Electrical Safety and a Safe Home

I was electrocuted twice in my own home, on the same day. The first shock came from my smart thermostat. The second shock came from my smart lock — the devices in my own walls, the ones I trusted every day. I died, and I came back.

Nobody had ever taught me what to look for. Nobody had told me a device that tingles is warning you, or that a small shock is never small. I am a Muslim Ordained Minister, and I built this app so that what I needed and did not have would exist for the next person. This page is that teaching, for your home: what is dangerous and what is safe, how to investigate your own home with your own eyes, and how to know the moment a thing stops being yours to handle and becomes a call you make. Read it in a calm season. A shock is never "nothing" — and after this page, you will know why, and you will know what to do.

Winter

• Space heaters: keep them three feet from anything that can burn — bedding, curtains, furniture, paper. Plug them straight into the wall, never into an extension cord or a power strip. Turn them off when you sleep and when you leave the room.
• Heating season loads the circuits: heaters, blankets, and kettles on one circuit is how breakers trip and wires heat. Spread heat-making things across rooms and outlets.
• Holiday lights: inspect every string before it goes up — cracked sockets and frayed wires go in the trash, not on the tree. Turn lights off overnight and when you leave.
• Frozen pipes near wiring: never use an open flame to thaw a pipe, and treat any pipe work near wiring as electrician-and-plumber territory, not a guess.

Spring

• Flooding and wet basements: never step into standing water that may be touching electricity — a submerged outlet, appliance, or panel makes the water itself dangerous. Stay out, and call the utility.
• Storm damage and downed lines: a downed power line is always treated as live — always, even if it is not sparking and even if your power is out. Stay far away, keep children and animals away, and call 911 or the utility.
• Yard work near lines: look up before ladders, poles, and tree work anywhere near overhead lines, and call 811 before digging near buried lines.

Summer

• Air conditioners draw heavily — give a window unit its own outlet, not a shared strip, and never an extension cord not rated for it.
• Pools, sprinklers, and cords: water and electricity again — keep cords and plugged-in devices away from the pool and out of wet grass paths, and use GFCI protection outside.
• Lightning: during a storm, be indoors, and stay away from plumbing and from devices plugged into the wall — a strike can travel through both.
• Generators: never run one indoors or in a garage — not even with the door open. Carbon monoxide kills quietly, and a generator connected wrong can send power back out into the lines and kill the workers repairing them. Plug appliances into the generator itself. The only safe way to connect a generator to a house is a proper transfer switch, installed by a licensed electrician.

Fall

• Heating season returns: have the furnace checked before the cold does, and give heaters their three feet from the first cold night, not the first fire.
• Wet leaves and yard cords: outdoor cords in wet leaves and rain must be rated for outdoors, off the wet ground where you can manage it, and inspected like any other cord.
• Early darkness: check the lighting on your paths, steps, and entrance — a lit way in is safety twice over.
• Prepare before winter: this is the season to walk the whole investigation below, test every detector, and fix what you found while the weather is still kind.

This is a calm walk-through you can do yourself, in one visit, without opening anything — no covers off, no panel opened, nothing inside a wall. You look, you listen, you smell, and where it is safe you check for warmth with the back of your hand (the back, so that if something is wrong your hand pulls away instead of gripping). Anything beyond this walk belongs to a licensed electrician.

Every room

• Cords: damaged, frayed, warm, pinched under furniture, or hidden under rugs?
• Outlets: warm to the touch, loose, discolored or scorched, buzzing or crackling?
• Switches: any that shock, spark, or feel warm?
• Lights: any that flicker, or dim when an appliance starts up? New flicker is information — write it down.

Kitchen and bathroom — the GFCI test

Look for outlets with TEST and RESET buttons near every sink. Then test each one, monthly:

1. Plug in a small lamp or night light and turn it on.
2. Press TEST. The light should go out, and the RESET button may pop out slightly. That click is the protection working.
3. Press RESET. The light should come back on.
4. If the light does not go out when you press TEST, the protection is dead — that outlet is on the electrician list until it is replaced.

The breaker panel — look, never open

• Are the breakers labelled, so you know which switch cuts which room? If not, labelling them — by switching one at a time and seeing what goes dark — is a calm two-person job. That is as far as it goes.
• Does one breaker keep tripping? It is reporting a fault. That circuit goes on the electrician list.
• Buzzing, a burning smell, or warmth at the panel: stop the walk, and call. Do not keep investigating a panel that is talking to you.
• Never open the panel's inside cover. The switches on the front are yours to use. Everything behind the cover is licensed work — that rule has no exceptions on this page.

Smart devices — from my own experience

A thermostat, a lock, a doorbell, any connected device: if it shocks you, tingles, overheats, buzzes, or acts on its own — cut its power at the breaker switch, and do not touch it again until a licensed electrician and the utility company have both seen it. Photograph it as it stands, and log everything: the date, the time, what happened, what your body felt, and who you told. That log is evidence, and it protects the next person too.

Outside

• Look — from the ground, never touching — at the service line coming to your home and at the meter: damage, scorching, or a meter that looks forced goes to the utility.
• Exterior outlets should have covers that close over them, and GFCI protection.
• Extension cords outside must be rated for outdoor use. An indoor cord outdoors is a failure waiting for rain.

Write the whole investigation down — one home, one page, dated: what you checked, what you found, what you fixed, and what is waiting on the electrician. Keep it with your records and walk it again each fall.

A licensed electrician — the same day, or this week

• Any tingle or shock from any device or appliance, however small.
• A breaker that trips more than once.
• A burning smell you cannot place, or any smell at the panel.
• Warm, loose, or scorched outlets and switches.
• Flickering that is new.
• Any smart device misbehaving — heating, buzzing, acting on its own.
• Water that has touched wiring, outlets, or appliances.

The utility company

• Downed, damaged, or low-hanging lines; a damaged or scorched meter.
• Power surging or dimming through the whole home at once.
• Any suspected problem between the street and your house — that stretch is theirs, and it is their job to check it.

If you rent — the landlord, in writing

Electrical hazards are the building owner's duty in most places. Put the notice in writing — the hazard, the date you found it, the date you sent it — and keep your copy with your records. Writing is what makes it real. If nothing is done, the next doors are your city or town building or code inspector, and your fire department's non-emergency line, which can check a hazard. A hazard you reported is a hazard on record.

If you or someone in your home takes a shock, the record you make is part of the care. Write down: the device, the date and the time, what happened, exactly what your body felt, and what care you got. Then:

• Get medical follow-up even when you feel fine. Say the words "electric shock" at the desk, so the visit is about the right thing. Effects on the heart can come later — that is why the check matters.
• Report the device to its maker — in writing, and keep their answer.
• Report it to the U.S. Consumer Product Safety Commission at SaferProducts.gov. Your report goes on record, and the pattern across families is how dangerous products get pulled. Your report may be the one that protects the next home.
• Keep the device, unplugged and untouched, until the electrician and the utility have seen it — and if anyone asks you to throw it away or hand it over quietly, write that down too, with the date and who asked.

Detectors are the home's own warning system — which makes them worth two kinds of attention on this page: whether yours are real and working, and whether anything has been hidden inside them. Both checks are yours to make.

Where real ones belong

• Smoke alarms: inside every bedroom, outside every sleeping area, and on every level of the home.
• Carbon monoxide alarms: near the sleeping areas, and near fuel-burning appliances — the furnace, the water heater, the stove, an attached garage.
• The monthly test: press TEST. A real alarm answers with a loud, real sound. Batteries are replaced on schedule, and the whole unit is replaced at ten years — the date on the back tells you its age.

How to know a real one

• It carries a maker's name and a model.
• It carries a certification mark — UL or ETL.
• It has a manufacture date stamped on the back. That stamp is the first check.
• It has sensor vents — the slots or mesh where smoke or gas reaches the sensor.
• Its TEST button actually sounds the alarm.
• If it is hardwired, the wiring is real and properly done, installed at the breaker like any other electrical work.

How to know a decoy

• It feels light and hollow in the hand.
• There is no manufacture date, and no certification mark.
• Its "test" does nothing at all — or only lights a small LED, with no sound.
• It has a dark lens in the center that a real detector does not have. Hold that thought — the next section is about it.

A detector that never sounds on test is not protecting anyone, whatever it looks like. Replace it. And if someone else installed a decoy where a real detector was required — in a rental, in a building you pay for — that is a reportable hazard: the landlord in writing, the fire department's non-emergency line, and the code inspector, the same doors as any other hazard in your home.

A detector hangs on the ceiling of the most private rooms in a home, with power and a reason to be there. That is exactly why a camera or a microphone can be hidden inside one. Here is how you check — and then how the same method sweeps the whole house.

Checking a detector for a hidden device

• Compare it with the maker's own photo of that model. An extra pinhole, a lens, a microphone hole, or a wire the real model does not have is the tell.
• The glint check: in a dark room, sweep a flashlight or your phone's light slowly across it. A camera lens glints back at you.
• The infrared check: your phone's front camera can show infrared lights glowing that your eyes cannot see.
• Your router's device list: a hidden camera that sends pictures has to send them somewhere. Every connected thing on your network should be yours.

The honest limit, plainly: no home check proves a negative. Small radio-frequency detector gadgets exist and are sold everywhere, and they are named here as resources only — certainty comes from a licensed professional sweep, and the sweep section below tells you how that door works.

The law, in plain words

Hidden cameras in private spaces — bathrooms, bedrooms, a tenant's own home — are illegal. Audio recording has its own laws, and they vary by state. This page teaches you that the laws exist and that the police are the door; it does not advise you on them, because this page is not legal advice.

If you find something

• Do not remove it and do not destroy it if a crime is possible. Photograph it in place, log it, and call the police — how it is handled decides whether it can be used in court.
• If you rent, notify the landlord in writing as well.
• In a hotel or a short-stay rental: leave the room, then call the police and the platform you booked through.
• If it is your own detector and it has been tampered with: power down at the breaker, and treat it the way the electrical sections teach — electrician, utility, and everything logged.

The whole-house sweep, step by step

Start with the private rooms — the bedroom and the bathroom. Aim your eyes the way a camera would aim: anything facing the bed, the shower, or where you dress. The hiding places, by name: smoke and carbon monoxide detectors; alarm clocks; phone chargers and USB wall plugs — including any charger you do not remember buying; televisions and smart displays; smart speakers; mirrors; air vents; picture frames; and any object that is new in your home and unexplained, including gifts that arrived unexpectedly.

1. The looking pass. Slowly, room by room: anything new, anything moved, anything with a pinhole or a wire it should not have.
2. The glint pass. Lights off, flashlight slow. Lenses glint back.
3. The infrared pass. Your phone's front camera, in the dark, looking for lights your eyes cannot see.
4. The router pass. Open your router's device list. Every connected thing should be yours. Change the router's admin password during the sweep — that step matters again in the WiFi section below.
5. The phone pass. Your phone's Bluetooth list, for devices you do not know — and your phone's unknown-tracker alerts, turned on.
6. The accounts pass. Your smart-home accounts: who has access, what logins exist. Remove anyone you do not know, and change the passwords from a device you trust.
7. Log the sweep itself. Every step and every find, dated, in your evidence log. The sweep becomes a record, and a record can be shown.

Mirrors, honestly: you may have heard of the fingernail test for two-way mirrors. It is taught here with its limit attached — it is not proof, either way. A mirror that worries you gets covered, and the police or a professional settle the question. A fingertip does not.

Where your own sweep ends: a careful home sweep catches what can be seen, and what rides on your own network. It cannot prove nothing is there. Where certainty matters — a court case, a stalker, a home that still does not feel safe — a licensed professional sweep (called a TSCM sweep) exists. Find that professional through a police or an attorney's referral — never through an advertisement that found you. And the reporting doors stand open: the police, for the device and the pattern; the FTC, for stalkerware on phones; and your state Attorney General's privacy office.

These signs are taught as patterns, never one sign alone. One strange thing is a question. The same strange thing, again and again, is an answer.

The strongest sign of all

Someone knows things that were only ever said inside your home, or only ever on your phone. Information leaking is the evidence — one leak is a question; a pattern of leaks is an answer. Log every leak: the date, the time, what was said, where you were when you said it, and who repeated it back to you.

Signs of a bug or a line tap

• Clicks, static, echoes, or volume changes on a landline.
• A radio or speaker picking up odd interference it never made before.
• Your phone line or the junction box outside showing marks, new wires, or a cover left open.
• "Repair" visits you never scheduled.

The honest line, in big words: a modern tap is usually silent and digital. No strange sounds does not mean no tap — and strange sounds alone do not prove one. Two real steps exist: the company that owns the line can test it, so ask your phone company to check the line; and a police report puts the pattern on record.

Signs your devices are compromised

• The battery draining far faster than it did before.
• The phone warm in your hand when you have not been using it.
• Data use spiking without a reason you can name.
• Apps on your phone that you never installed.
• Settings changed that you did not change.
• The microphone or camera indicator dot — orange or green — appearing when you are not using either one.
• Smart devices acting on their own: locks, a thermostat, speakers. My own testimony is the standing example of this sign, and it is taught whole on the Journey page.
• Accounts signed in from places you have never been.

Signs of hidden cameras

• A lens glint where no lens belongs.
• Tiny red or purple dots glowing in a dark room — infrared, seeing in the dark.
• An object aimed at a private space, with a pinhole.
• An unknown device riding on your Wi-Fi.
• A smart TV or monitor camera you never set up, showing activity lights.

How to respond, in order

1. Do not discuss your suspicions on the suspected phone, on the suspected line, or in the suspected room. Talk from somewhere else, on a device you trust.
2. Log everything first — dates and times — before you touch anything.
3. Report: the police, and your phone company for the line check.
4. For proof that holds in court, the licensed professional sweep (TSCM). Your own checks can find signs; only a professional sweep and the authorities can certify and act.

One lawful-tap note, plainly: a tap is lawful only when it is carried out by authorities under a court order. Anyone else listening is committing a crime — whatever they claim, and whatever name they give it.

The signs section above named a compromised phone as one of the patterns — the draining battery, the settings you did not change, the accounts signed in from places you have never been. This section is the phone itself, taken slowly: how to check whether your calls are being forwarded, how to know if your number has been cloned or swapped, how to know if someone is controlling the phone from another device or has set restrictions on it without your knowledge, and the security settings that close those doors. It goes on to teach Bluetooth and roaming, why your internet address keeps changing from place to place, how to track the phone itself, what to do when the phone is lost or taken — and what to do if you are taken — and how the authorities can find you. Every check here is free, and built into the phone already in your hand.

One pairing to know: this section is about the phone in your hand. The paper the phone company keeps — your itemized statements, and what they can prove — is taught on the Rights page, under Phone records. The two teachings belong together.

Check your call forwarding — the codes

Call forwarding sends your calls to another number without your phone ever ringing. Set on purpose, it is a convenience. Set in secret, it is how calls meant for you — including the calls that carry bank and account codes — can reach someone else. There are two ways to check: dial codes, and your phone's settings. Use both.

The codes. Type them into the phone keypad exactly as written, as if dialling a number:

• *#21# — checks all-call forwarding: whether every call to your number is being sent somewhere else, and to what number.
• *#62# — checks forwarding when you cannot be reached: your phone off, or out of signal.
• *#67# — checks forwarding when your line is busy.
• ##002# — cancels all call forwarding at once, every kind. One honest note: on many networks this also clears the rules that send missed calls to voicemail, so check your voicemail still answers the way you expect afterwards, and re-check with *#21# to see the line clear.
• *#06# — shows your phone's IMEI, its own identity number. Compare it with the IMEI on your carrier account and on the phone's original box or receipt. If the numbers do not match, that is a question for your carrier, asked promptly.

Reading the answer, honestly. "Not forwarded" or "disabled" is the calm answer. If a number is shown, do not panic at the sight of it: very often it is simply your voicemail number — carriers route missed calls through a number of their own, and that is normal. The red flag is a number you do not recognize and never set. If you find one: screenshot the screen, write it in your log with the date, dial ##002#, check again with *#21#, and then call your carrier.

And the carriers-vary line, because it is true: these codes come from the GSM standard most of the world's networks follow, but carriers vary — some use codes of their own (Verizon, for example, has long used *73 to turn off immediate forwarding), some phones or plans block the codes, and an "invalid MMI code" message means only that your carrier does not support that code. It is not proof of anything, good or bad. Your carrier's own support page, for your own line, is the final word.

The settings path — the second way. On iPhone: Settings → Phone → Call Forwarding shows the switch and the number. On Android: open the Phone app → Settings → Calling accounts → your line → Call forwarding (the names vary a little by maker). If the settings and the codes ever disagree, believe the question is worth a call to the carrier.

If your phone or your number is cloned

First, the honest distinction, because the words are used loosely. True SIM cloning — copying your SIM card itself — is rare now; modern SIMs resist it. The common modern versions are these two:

• The SIM swap: someone fools your carrier — with stolen personal details and a story — into moving your number onto their SIM. Your phone goes dead; your number, and every code texted to it, goes to them.
• Spoofing: your number is simply displayed on calls you never made. Nothing of yours is taken, but people believe you called.

The signs:

• Your phone suddenly has no service — "SIM not provisioned" or no signal at all — while phones around you work fine.
• The carrier tells you your number was activated on a new device, or a change was made you never asked for.
• People tell you they received calls or texts from your number that you never sent.
• One-time codes arrive that you did not request — someone is at a door, trying keys.
• Accounts begin to be entered from the codes side: password resets and sign-ins you did not start.

The response, in order:

1. Call your carrier from another phone — a family member's, a workplace phone, any phone that is not yours. Say the words "SIM swap." Have the account frozen, your number taken back onto a SIM in your own hand, and a SIM-change / port-out PIN and an account password set before you hang up. That PIN is the lock this whole attack walked around.
2. Call your bank. Your number guards your money, because it receives the codes. Tell them the number was swapped and to watch the accounts.
3. Change your email password — from a device you trust. Email is the master key: it resets everything else, so it is secured third, immediately.
4. Log it and report it. Dates, times, what the carrier said, the new PIN set — into your log. A police report puts it on record, and the Rights page teaches the rest of the paper.

Controlled from another device

The signs: the screen wakes or acts on its own; apps open that you did not open; settings and passwords change that you did not change; someone knows what is on your screen, or where you are, in ways they should not; a screen-sharing or remote-control app sits on the phone that you never installed; sharing and family features are turned on that you did not set — location sharing lists, screen time, the list of devices on your account.

Two checks that find what eyes miss:

• On iPhone: Settings → General → VPN & Device Management. A management profile there can set rules over the whole phone. One you recognize, from your own employer or school, is ordinary. One you do not recognize is not.
• On Android: Settings → Security → Device admin apps, and Settings → Accessibility → Installed apps. An unknown app switched ON in either place can watch the screen, read what you type, or act in your name. Accessibility is a powerful door: only apps you chose on purpose should hold it.

The response: work from a device you trust — not the phone in question.

1. Change the account password — your Apple ID or your Google account — from the trusted device.
2. Sign out every other device. Both accounts show the list of devices signed in as you (in your Apple ID settings, and at your Google account's "Your devices" page). Remove every device you do not recognize, and any you no longer own.
3. Remove unknown profiles and apps — the management profile you never agreed to, the device-admin or accessibility app you never installed.
4. Review every sharing list, person by person — who can see your location, your photos, your files. Remove anyone who should not be there, one name at a time, and know each name that remains.
5. If it continues, the carrier and the police are the next doors, and the Rights page teaches the reports. A phone that stays controlled after all of this is evidence, and it is treated like the devices in the sweep section: logged, photographed, and reported — not argued with.

Restrictions set without you knowing

A phone can be quietly fenced in. Someone with a moment of access — or the person who "organizes" the account — can set Screen Time limits behind a passcode you do not know (iPhone), Family Link or parental controls (Android), app and content blocks, communication limits, downtime schedules that lock the phone at hours you never chose, buying blocks, a management (MDM) profile, and restrictions at the carrier account itself.

The signs: apps greyed out or blocked at certain hours; settings you cannot change; messages saying this device is "managed"; apps you cannot install or delete; a Screen Time passcode prompt for a passcode that was never yours.

The response, in order:

1. Find out who organizes the account. Restrictions follow the account, not the phone in your hand. The organizer's name is in the family-sharing settings (iPhone) or Family Link (Android). That name is where the lock actually lives.
2. Use the owner's own doors. An adult's own Screen Time passcode can be reset with their own Apple ID — the "Forgot Passcode?" path uses it. On Android, the controls are removed by the account holder inside Family Link. Carrier restrictions are added and removed by the carrier account holder, and by no one else.
3. Hear the plain truth: if the account and the line are in someone else's name, that is the real lock — and no setting on the handset undoes it. A line of your own, in your own name, under an account only you hold, is the durable fix. It is not the fast fix, and this page will not pretend otherwise; it is the one that stays fixed.

Knowing phone security — one calm checklist

Everything above is response. This is prevention: one checklist, finished in one sitting, and re-checked any time a sign from this section appears. Tick each one as you set it. The ticks are remembered only on this device — nothing is sent anywhere.

• A strong passcode — and not a birthday. Not your birth date, not a child's, not an anniversary: those are the first numbers anyone who knows you will try. The vault rule applies to the phone: the key is never a date your life is written in.
• Face or fingerprint unlock ON. Your face and your finger cannot be guessed, shared by accident, or watched over your shoulder.
• Automatic updates ON — for the phone's system and for its apps. Updates are where the holes get closed; a phone that waits is a phone standing open.
• Two-factor on the accounts that matter — and app-based codes where they are offered. A texted code rides the same number a SIM swap steals; an authenticator app does not.
• A carrier account PIN, with SIM-change / port-out protection ON. Set at the carrier, once. This single setting defeats most swaps, because the story that fools a clerk cannot supply a PIN it does not know.
• Find My / Find My Device ON. A lost or taken phone can be found, locked, and — at the last resort — erased, instead of simply gone.
• Permissions reviewed. Which apps hold your microphone, your camera, your location — trimmed to what each app truly needs to do its job. The location teaching below goes deeper.
• Backups ON. So a lost, seized, or replaced phone is an inconvenience — not an erasure of your records, your photos, and your proof.
• Public Wi-Fi treated as a public room. Anyone may be listening in a public room, so no banking and no private business on a café's or a store's open network. Wait for your own connection.
• Lock-screen notifications narrowed. The phone may announce that a message arrived; it should not display the message — or a sign-in code — to whoever picks it up. The ON / OFF lists below carry the exact settings.

Geo tagging — the location hidden inside your photos

Most phones stamp the exact GPS location into every photograph — hidden data, called EXIF, that travels with the picture wherever the picture goes. A photo posted or sent can carry your home's coordinates inside it, invisibly, to anyone who receives it.

• Turn camera location OFF: on iPhone, Settings → Privacy & Security → Location Services → Camera → Never. On Android, open the Camera app's settings and turn Location tags off.
• Strip the location before sharing a photo that already has it: on iPhone, in the share sheet tap Options and turn Location off before you send. On many Android phones, the photo's Details offer a "remove location" option — look there before the picture goes out.
• Know the difference between doors: the big social platforms usually strip location data when a photo is posted. A photo sent by message or email often keeps it whole. The same picture is safe through one door and exposed through the other.

Your child's school, your front door, the address of the place you are safe — all of them can ride inside a picture, silently. Check the photo before the photo goes out.

Locations — every door your phone keeps on where you are

Location is not one setting. It is a hallway of doors, and this is the walk down it.

• The master door: Location Services. On iPhone, Settings → Privacy & Security → Location Services; on Android, Settings → Location. This is the one switch above all the apps — and below it, every app has a door of its own.
• The per-app choices, in plain words: Never — the app never knows where you are. While Using (only while I use it) — the app knows while it is open in your hand, and not after. Always — the app knows day and night, open or closed. Very few apps have earned Always; most never will.
• Precise versus approximate. Precise is your exact spot. Approximate is the neighborhood — and the neighborhood is enough for weather, news, and store hours. Where a phone offers the choice, approximate is the safer default for anything that is not giving you directions.
• The phone's own memory of where you have been. On iPhone it is called Significant Locations (Settings → Privacy & Security → Location Services → System Services → Significant Locations): you can see the list, clear it, and turn it off. On Google accounts it is Location History / Timeline: you can see the map it has drawn of your life, delete a day or all of it, and pause it so it stops drawing. Know why this matters: that history is a map of your whole life, and anyone who gets into your account — or holds it as its organizer — can open the map.
• Sharing lists, reviewed person by person. Family sharing can show your live location to everyone on the list. Know every name on yours, the way the control section above teaches — a list you have never read is a list someone else may have written.
• The quiet carriers of location most people forget: fitness apps that publish your running routes, car and insurance apps that follow the driving, store and weather apps that never needed to know. Each one holds a piece of the map.

The rule, printed once for the whole hallway: every app that holds your location should be able to answer one question — why do you need to know where I am? An app that cannot answer it gets Never.

Bluetooth safety — the radio door

Bluetooth is a short radio reach between your phone and things near it: earbuds, speakers, a car's dashboard, another person's phone. Teach yourself to treat it the way you treat a door — because that is what it is. A door you are not using should be closed.

• Turn Bluetooth OFF when you are not using it. It belongs on the OFF list in public places, from the lists above: an open radio, listening all day in crowds, is an open door. Turn it on for the earbuds, off when the earbuds go away.
• Never accept a pairing request you did not start. A pairing prompt that appears while you are sitting in a waiting room or on a bus is not a gift; it is a knock from a stranger. Decline it. Pairing is begun by you, for a device in your own hand, or not at all.
• Keep the phone non-discoverable. Most modern phones are only visible to other devices while the Bluetooth settings screen is open — so do not sit with that screen open in public, and close it when you are done pairing.
• Review the paired-devices list, and FORGET what you no longer own or use. Old cars, old speakers, a friend's device from two years ago, a rental from one trip — every forgotten pairing is a door left standing open to a device that is no longer yours. Open the list, read every name, and forget each one that is not in your life now.
• Trim app Bluetooth permissions the same way you trimmed location. An app that asks for Bluetooth should be able to answer why — the rule from the location teaching applies here word for word: why do you need this door?
• Keep the phone updated. Holes in Bluetooth are found and fixed in the system's updates — one more reason automatic updates stay ON.

One tie-in, so the two teachings do not fight: the same Bluetooth radio is how unknown trackers announce themselves to your phone — it is the radio your tracker alerts listen on. Narrow your Bluetooth use as taught here, and keep the unknown-tracker alerts ON regardless, so the warnings still reach you.

Roaming — your phone on another company's towers

What roaming is, in plain words: your phone is using another company's towers, because your own company's towers are not there. The phone keeps working; it is simply a guest on someone else's network — and guests are treated by different rules.

• Domestic roaming — inside your own country. It is often included in modern plans, but not always, and not without limits. Many phones show the word "roaming," or a small R, when it is happening. See the R, and know where you stand before you stream an afternoon of video on it.
• International roaming — in another country. This is the expensive kind: calls, texts, and above all data can be charged by the minute and by the megabyte, at rates nothing like home. And the quiet danger is the background: a phone updating its apps, backing up its photos, and fetching its mail over foreign towers can build a real bill while it sits in your pocket, never once rung.

Prepare before a trip, not after the bill:

1. Choose your path at your own carrier, in its own app or store: a travel pass for the days you are away, or — for a longer stay — an eSIM or local SIM bought from an official store at your destination.
2. Download before you go, on home Wi-Fi: maps, tickets, papers, books, anything the trip needs. What is already on the phone costs nothing abroad.
3. Turn DATA ROAMING OFF until you choose to use it. On iPhone: Settings → Cellular → Cellular Data Options → Data Roaming. On Android: Settings → Network & internet (names vary a little by maker) → your SIM → Roaming. Off is the default that protects you; turn it on deliberately, for a reason, and know the price first.
4. Use airplane mode + Wi-Fi as the free path in hotels and homes abroad: airplane mode on so the phone cannot wander onto foreign towers, Wi-Fi on for the network you trust. Calls and messages ride the Wi-Fi; no roaming meter runs.

The safety tie-ins, because this is a safety page: a roaming phone announces itself to foreign towers and creates location records with two companies instead of one — yours and theirs — which ties straight back to the Locations teaching above. At airports, beware the scam version of this worry: sellers of "free Wi-Fi" and travel plans who appeared from nowhere, and texts that arrive asking you to "confirm your roaming" through a link. The real roaming balance is checked in your carrier's own app — never through a link in a text.

Your IP address — why it keeps changing, and what it can and cannot say

An IP address is the return address your connection uses — the address answers come back to, the way a letter finds its way home. And for most people it is not fixed. Your home router hands your phone one address. The café's router hands it another. The cell tower hands it another still, and your provider rotates the addresses it hands out — addresses that change like this are called dynamic.

• A changing address is normal. It is not, by itself, a sign of hacking. It is how the system is built.
• Sign-in alerts may name a town you have never visited. The address your carrier handed you may belong to their hub in that town. An alert saying "signed in from" a city an hour away is usually this — read it, and check it against what you were doing, before you fear it.
• Thousands of customers can share one outward address at a carrier. Your whole street's traffic may leave through a handful of addresses. Which is why the rule below is printed as a rule:

AN IP ADDRESS IS A LEAD, NOT A PERSON. It points to a connection — a router, a tower assignment, a moment. It does not point to a human hand. Tying an address to a person takes the company's records, and more — which is why, on the Rights page, records and logs carry the weight they do, and why your own dated log matters more than any address ever will.

About VPNs, taught as a choice with honest limits: a VPN routes your connection through another company's address, in another place, on purpose. It hides your address from the sites you visit — and the VPN company then holds the connection records instead. You are choosing who keeps the paper, not erasing the paper. For some people that trade is right; know that it is a trade.

How to see your own current address: your phone's Wi-Fi settings show the address your router handed it (iPhone: Settings → Wi-Fi → the network's information; Android: Settings → Network & internet → Wi-Fi → the network's details). Your outward address — the one the world sees — is shown by your carrier's tools or a "what is my IP" page. And one last understanding for a person being tracked: addresses change, but accounts follow you. Signing into your account names you on any address, from any router, anywhere. The account, not the address, is the thread that follows.

How to track your own device

Tracking your phone is set up before anything is lost — a calm-season job, like the cards on the Missing Persons page. Set up in the bad hour, it is too late; the bad hour is when it pays.

• On iPhone — Apple Find My: Settings → your name → Find My → Find My iPhone, turned ON — including Send Last Location, so a dying battery still reports where the phone was when it faded.
• On Android — Google Find My Device: Settings → Security → Find My Device, turned ON (the path varies a little by maker). If it is not there, your maker's own find service may be — Samsung's is called SmartThings Find.

What you get, once it is on: a map showing where the phone is, or where it last was. Play Sound — the phone rings at full volume even on silent, for the phone lost in your own house. And Lost Mode — it locks the phone and shows your message on its screen, with a callback number you choose, so an honest finder knows exactly how to hand it back.

Erase is the LAST step, and only the last. Erasing wipes the phone clean — and ends the tracking with it. A wiped phone cannot be followed. Erase only when the phone is gone for good and the choice is between your information in a stranger's hands and the phone itself. Everything before that moment: map, sound, Lost Mode, carrier, police.

Your IMEI belongs in your ahead-of-time records — from *#06#, taught at the top of this section, or from your carrier account. A police report carrying the IMEI is what lets police and carriers flag the device itself, in every system that watches for stolen phones. The Be Findable sheet has a field waiting for it.

If the phone is lost or stolen — and if someone takes YOU

The device, in order:

1. Find My first: the map, Play Sound if it may simply be near, then Lost Mode with your callback number.
2. Call your carrier: suspend the line and have the device flagged by its IMEI, so it cannot quietly live a second life on the network.
3. Police report, with the IMEI in it. Location screenshots from the map go with it — dated, unedited.
4. Change your account passwords from a trusted device — email first, then the bank, then the rest — and sign out the lost phone everywhere, the way the control section above teaches. The phone was a key; treat its loss as a lock change.
5. Watch the accounts for a while after: sign-in alerts, reset attempts, codes you did not ask for. The phone section's signs are your watchlist now.

And the person — because a phone is also how you are found. Set these up ahead, in the calm season:

• Emergency SOS. On both systems, pressing the side or power button rapidly, several times, calls emergency services and alerts your emergency contacts with your location. On iPhone it is Settings → Emergency SOS; on Android, Settings → Safety & emergency → Emergency SOS (makers vary a little). Learn where it lives on your phone, and practice the motion once, so your hand knows it when your mind is full of fear.
• Live location, shared with your person — your one trusted person, from the sharing lists above — and a check-in habit: agreed times when your person hears from you, and an agreed meaning when they do not.
• A family code word. One ordinary-sounding word or phrase that means, when you say it or text it, "send police to my location." It works because it can be said out loud in front of anyone — in a car, on a call someone else is listening to — and sound like nothing at all. Choose it together, in advance, and keep it inside the family. The Be Findable system has a place for it, and a tick box for the day you have taught it to your person.

If you are taken: leave a trail. Belongings dropped where they will be found. A call or text made on purpose, where it is safe, even a short one. Names, street names, and places said aloud near any phone or camera — voices carry to microphones you cannot see, and recordings remember what fear forgets. And if you get one moment with a phone — any phone, even one with no plan on any carrier — 911 first. An emergency call works without a plan. Words, explanations, everything else: second.

This is the same road as the Car & Street Safety page's getting home safe teaching — never lead danger home, go to people and light, help first and explanations after. The two pages belong together, and in a hard hour either one will walk you to the other.

How authorities can find you

Taught plainly, so a family in the worst hour knows what police can actually do — and what the family can hand them to make it faster.

• A 911 call from a cell phone carries your location to the dispatcher. Wireless location rules require it. Know its honest limit: outdoors it can be close; indoors it may be a building, not a room. So when you can speak, say where you are — the building, the floor, the room — and do not hang up. Your voice finishes what the signal starts.
• In a true emergency, police can ask your carrier to locate your phone, urgently. Carriers keep emergency-disclosure doors for exactly this — a life at risk, minutes mattering. Outside an emergency, it is different by law: live tracking and past location records go through court process — warrants and court orders. That line between emergency and process is the Carpenter case, taught with its story on the Rights page's real cases. Both halves protect people: the emergency door moves fast when a life is on the line, and the court door keeps the map of a life from being opened for less.
• Your own tools, shown to officers on the spot, are often the fastest of all. Your person opens Find My and turns the screen to the officer. Your IMEI flags the device. Your vehicle's plate and description go out to every patrol car. A child's or elder's tracker — from the Missing Persons page's children's tracking and elder teachings — speaks for the one who cannot.

What your family hands them decides the speed. A family searching its memory in a panic is slow. A family handing over one page is fast: your number; your carrier; your phone's model and its IMEI; who holds your accounts; your check-in plan and your code word; your last known place, and the time you were known to be there. That page already exists as a system in this app — it is the Be Findable sheet, filled in a calm season, printed twice, one copy in your person's hands. Build it before anybody needs it.

The honest closing line: location is fast when the phone is on and charged. A dead phone reports its last location and then goes silent. So battery habits — the charger by the door, the low-battery warning answered instead of dismissed, the portable battery in the bag — and the check-in plan are not small things. They are part of being findable.

This is the newest part of this page, and the strangest to hear. Read it slowly.

What it is, in plain words. WiFi signals fill a space the way light fills a room — and when a body moves through them, the waves bend and scatter. Technology now reads those changes. It is called WiFi sensing, and it can detect that a person is present, where in the space they are moving, and even their posture — through walls, in the dark, with no camera anywhere, and nothing worn or carried by the person. What began in research laboratories is now sold inside ordinary products: some internet providers and router systems offer WiFi motion detection as a feature, under names like Xfinity's WiFi Motion, Linksys Aware, and Plume Motion, and smart-home systems use it in place of motion sensors.

Why it matters

Every check in the sweep section above depends on one thing: a camera has a lens, and a lens can be found. WiFi sensing has no lens, no light, and nothing to find — the router itself is the sensor. A person can be followed room to room inside their own home by whoever controls that network: an abusive partner who holds the router password; a landlord's system running in a rental, never mentioned; a business watching how people move through it, without ever saying so.

At home — what you can do

• Check your own router, by name. Open your router's app and its settings, and look for features named motion detection, presence sensing, or WiFi sensing. If you did not turn it on and agree to it, turn it off.
• Guard the admin password like a house key — because that is what it is. Whoever holds the router password holds the sensing. This is the same router pass as in the sweep: the device list, the password changed, the firmware kept updated.
• Know the honest limit: settings on your router control your network. They cannot block sensing run on someone else's network. And be warned about the scam version of this worry: paid "blocker" gadgets and foil-and-shielding claims sold to frightened people do not do what they promise. The real protection at home is controlling your own router — and knowing the feature exists.

In businesses and public spaces

You cannot control their networks, so the teaching here is awareness and choice. Sensing may be running anywhere WiFi is offered. Know what it reads and what it does not: it reads presence and movement — not identity, by itself. And know that the laws and policies about disclosing it are still being written, which is exactly why awareness matters now.

The teaching on this page stands on named doors, and you can check every one of them yourself: the Electrical Safety Foundation International (ESFI), at esfi.org; the U.S. Consumer Product Safety Commission, at cpsc.gov — and its reporting door, SaferProducts.gov; the NFPA (the National Fire Protection Association), at nfpa.org, whose code and detector teaching this page follows; and your own utility company, whose number is on your bill and whose job includes the lines and the meter outside your home. Where this page and an official source ever differ, follow the official source and your licensed electrician — and tell us, so the page can be corrected.

A dangerous device, a decoy detector, a hidden camera, a tap — these are not only safety problems. They are legal matters, and the law has doors for them. This app's legal section, Your Legal Rights and Your Case, holds the documents you can fill out online, print, or save — including the CPSC product report and the landlord's written notice taught on this page — the checklist, the step-by-step guide, how to prepare and present your case in court, real cases including a landlord caught with cameras in a smoke detector, the money that exists for victims, and how proof is built. The log this page taught you to keep is where that proof begins.

Free doors for this section: utility-bill help (LIHEAP) through the USA.gov Benefit Finder; local help of every kind by dialing 2-1-1; report a dangerous product free at SaferProducts.gov (the U.S. Consumer Product Safety Commission); help after a house fire from the American Red Cross.
