Picture a map of everywhere you went last Tuesday. Your home, the coffee place, the doctor’s office, the gym, a friend’s apartment, and back home again, all time-stamped to the minute. You never drew that map. Your phone did, and depending on your settings, several companies you have never heard of may own a copy of it.
Location is the most revealing thing your phone gives away, because it shows patterns no other data can. The good news: a handful of switches take back most of that visibility, and you can flip them in about half an hour.
Key takeaways
- Your phone builds a detailed history of your daily movements unless you tell it to stop.
- Two layers matter: the system location switch and per-app permissions.
- “While Using” plus “Precise Location off” is the sweet spot for most apps.
- An advertising ID quietly ties your location to ads, and you can reset or delete it.
- Turning tracking off almost never breaks the apps you actually rely on.
What “location tracking” really means
There is not one location setting. There are several, stacked on top of each other, and each one leaks a different amount.
The first layer is your device’s master location service, the thing that lets Maps find you. The second is per-app permission: which apps may read that location, and whether they can do it in the background. The third is quieter, an advertising identifier that ad networks use to match your movements to profiles.
You do not need to kill all of it. You need to stop the background logging and the ad matching, which is where the real exposure lives. This is one of the core moves in our overview of everyday online privacy, and it pays off faster than almost anything else.
Turning off location for an app does not mean it can never find you. It means the app has to ask again, in context, the next time a feature genuinely needs your position.
Turn off location tracking on an iPhone
Open Settings, tap Privacy and Security, then Location Services. This screen lists every app and how much location access it has right now. Most people are surprised by how long the list is.
Fix the worst offenders first
Look for anything set to “Always.” That is the setting that logs you in the background, even when the app is closed. Unless it is a genuine need like a navigation or family-safety app, change it to “While Using the App” or “Never.”
Inside each app you will also see “Precise Location.” A weather app, a news app, or a shopping app works perfectly with this off, which shares only your rough neighborhood instead of your exact doorstep.
Scroll to the very bottom of Location Services and tap System Services. Turn off “Location-Based Ads” and “Significant Locations.” That second one is a running log of the places you visit most, and few people know it exists.
Turn off location tracking on Android
The path varies a little by brand, but the idea holds. Open Settings, tap Location, then App location permissions (sometimes under Permission Manager). You will see apps sorted by how much access they hold.
Set each app to “Allow only while using the app” or “Don’t allow.” For apps you rarely open, “Ask every time” is a tidy middle ground. Then look for “Use precise location” inside an app’s settings and switch it off wherever you only need a general area.
Android also keeps a Location History tied to your Google account. Open Settings, tap Location, then Location Services, and review Timeline or Location History. You can pause it and delete what is already stored.
The advertising ID nobody mentions
Both phones carry a resettable advertising ID that ad networks use to stitch your activity together, location included. Cutting it off closes a door that per-app settings leave open.
| Setting | Where to find it (iPhone) | Where to find it (Android) |
|---|---|---|
| Master location switch | Settings, Privacy and Security, Location Services | Settings, Location |
| Per-app location | Location Services, tap each app | Location, App location permissions |
| Precise location | Inside each app, Precise Location toggle | Inside each app, Use precise location |
| Advertising ID | Settings, Privacy, Tracking (turn off “Allow Apps to Request to Track”) | Settings, Privacy, Ads (Delete advertising ID) |
A free flashlight, wallpaper, or simple game asking for location has no honest reason to want it. When I helped my dad clean up his phone, three “free” games all had background location. We deleted them outright rather than just changing the setting.
Where else your location leaks
Your phone is not the only source. Photos you post often carry GPS tags, and social apps guess your location from them. If you want the tags off, our guide to locking down your social media privacy covers where to switch that off before you share.
Apps also grab location alongside other sensors, so it is worth doing a full sweep once. Our walkthrough on reviewing every app permission on your phone pairs neatly with this one and takes about the same time.
Loyalty apps and check-ins
Store apps, coffee-chain rewards, and check-in features are easy to forget, and they are some of the hungriest for location. A rewards app does not need to know where you are at 2 a.m. on a Sunday. Set these to “While Using” and they still scan a code at the register just fine.
For a plain, no-hype reference on why location data matters, the FTC’s guidance at consumer.ftc.gov is worth a read.
How long this takes and what to expect
The whole sweep runs about 30-40 minutes the first time, mostly because reading the app list is slow. After that, spot checks take five minutes.
Expect one or two apps to nudge you to re-enable location later, usually with a banner that says a feature “works better” with it on. That is fine to ignore unless the feature is one you actually use. If a map app genuinely needs your position, grant it in the moment and move on.
You will also notice your phone battery lasts a touch longer, since fewer apps are polling GPS in the background. That is a small, pleasant side effect of a change you made for privacy.
Your afternoon checklist
- Open Location Services (iPhone) or Location (Android) and read the full app list.
- Change every “Always” app you do not fully trust to “While Using” or “Never.”
- Turn off Precise Location for weather, news, shopping, and social apps.
- On iPhone, open System Services and turn off Location-Based Ads and Significant Locations.
- On Android, pause and clear Location History or Timeline in your Google account.
- Delete or reset your advertising ID in the privacy settings.
- Uninstall any simple app that demanded location for no clear reason.
Half an hour of tapping buys you back a piece of daily life that was never anyone else’s business. Start with the “Always” apps tonight, and enjoy knowing your Tuesday belongs to you again.
