Decision sheet — Android & iPhone
iPhone tracker permissions
On iPhone, Settings › Privacy & Security is the single place that shows which apps may use your location, contacts, photos, microphone, camera and other data. Location Services lists every app that asked for location, with its setting and a Precise Location switch. An app cannot use location until it has asked and you said yes, and you can change that answer at any time. Nothing outside the phone can flip these switches for you.

On iPhone, Location Services and Privacy & Security show which apps may access location and other data, and the owner can change every one of those choices. Apple's help states that apps won't use your location until they have asked for permission and you grant it.
How to read an app's permissions on iPhone
- Open Settings › Privacy & Security. Apple lists the categories an app can ask for — Location Services, Contacts, Calendars, Photos, Bluetooth, Microphone, Camera, Motion & Fitness and more. Tap a category to see every app that requested it; an app appears only after it has asked.
- Open Location Services and tap the app. You see its current setting (such as Never, Ask Next Time, While Using, or always in the background) and the developer's explanation for asking. Choose the narrowest setting that still makes the feature work.
- Decide on Precise Location separately. Leave it on only if the app needs your specific location; Apple says approximate location may be sufficient for an app that doesn't need your exact location.
- Watch the status bar. A black or white arrow appears when an app is using Location Services, and a blue pill appears when an app is using location in the background.
- Turn on App Privacy Report (Settings › Privacy & Security › App Privacy Report, iOS 15.2 and later). It records, for the past 7 days, when each app accessed location, camera, microphone and other data, and which web domains it contacted. It only starts gathering after you turn it on.
- Read the app's own policy. Apple notes that once you let a third-party app use your data or location, you are subject to its terms and privacy practices — so the iPhone setting decides access, and the app's policy decides what happens next.
What does Location Services show for the app?
Open Settings › Privacy & Security › Location Services, tap the app, and pick what you see.
No location access.
The app cannot use Location Services. Apple's own safety checklist uses exactly this setting to stop sharing location with a particular app.
Do this: Nothing to change; check its other permissions under Privacy & Security.
You decide at each request.
Apple's help says that with Ask Next Time you are asked again the next time the app tries to use location. At that prompt, “Allow Once” gives it location for one session only.
Do this: Good for apps you open rarely; leave it.
The usual right answer.
The app may use location while you are using it. Apple counts background use with a visible blue pill in the status bar as “in use” too, so watch for that pill.
Do this: Check that Precise Location matches what the feature really needs.
Background access — the widest setting.
The app may use location in the background. Your iPhone reminds you from time to time, shows the locations it used on a map, and asks whether you want to keep allowing it.
Do this: Keep it only for a feature that must work while the app is closed; otherwise switch to While Using.
It never asked.
Apple's help says an app won't appear in a category until it asks permission to use that data. No entry means no request — and no access.
Do this: Look at the other categories; location is only one permission.
Edge cases — what the switches do and do not cover
- System Services are separate
- Settings › Privacy & Security › Location Services › System Services controls Apple's own services, such as location-based suggestions and ads. They are not listed with third-party apps, so review that page on its own.
- Turning Location Services off
- Turning it off stops all apps, even Maps, from using location, and Apple says no one is notified. Apple also notes that third-party apps and websites may still use other ways to estimate your location, and emergency calls can still share it.
- App Privacy Report starts empty
- The report gathers information only after you turn it on and keeps 7 days on the device. Turning it off clears the report data. It cannot show what happened before you enabled it.
- Safety Check needs iOS 16
- Safety Check (Settings › Privacy & Security › Safety Check) can reset system privacy permissions for apps and stop sharing with people. It requires iOS 16 or later and an Apple Account with two-factor authentication; on older versions Apple provides manual checklists.
- iCloud is a separate list
- Apple notes that if you sign in to iCloud, apps are granted access to iCloud Drive by default. That list is managed under iCloud in Settings, not under Location Services, so review it on its own.
- Reset everything at once
- Settings › General › Transfer or Reset iPhone › Reset › Reset Location & Privacy returns every location and privacy setting to default. Apps then stop using location until you grant permission again.
iPhone location settings side by side
| Never | Ask Next Time | While Using | Always | |
|---|---|---|---|---|
| When the app can read location | Never | Only after asking again | While you use it | Also in the background |
| Visible sign | None | A prompt | Arrow in the status bar | Blue pill, periodic reminders with a map |
| Precise Location switch | Not applicable | Yes | Yes | Yes |
| Typical honest use | Apps with no location feature | Apps you open now and then | Maps, delivery, weather | Continuous sharing you chose, such as a family app |
| Shown in App Privacy Report | No access to show | Yes, when used | Yes, when used | Yes, when used |
| Where to change it | Settings › Privacy & Security › Location Services › the app | Same | Same | Same |
Precision and duration are different choices
Approximate location
Turn Precise Location off for the app. This changes how exact the location is, not when the app may use it — review both settings.
Location Services
This controls which apps can read location. People you share with in Find My or a family app are a different list, managed in that app or in Safety Check.
Previously shared information
Changing a permission stops future access. It does not recall a screenshot, and Apple's help does not describe it deleting data an app's provider already holds.
Too many apps to review
Use Safety Check › Manage Sharing & Access on iOS 16 and later; it walks you through people and apps in one pass.
Permissions on iPhone are granted by the person using the phone, at the app's own prompt or in Settings. Apple's help states apps won't use your location until they ask and you grant permission. No website, link or phone number can grant an app access from outside, so services that claim to “unlock” an iPhone's location remotely are describing something Apple does not describe.

Questions people ask
Where do I see which apps can use my location on iPhone?
Settings › Privacy & Security › Location Services. Every app that asked for location is listed with its current setting. Tap an app to change it or to read its explanation for asking.
What does “Allow Once” do?
It lets an app use Location Services for one session only. If you close and reopen the app and it tries again, it has to ask for permission again.
What does turning off Precise Location change?
The app gets only your approximate location instead of your specific location. Apple says that may be sufficient for an app that doesn't need your exact location. Apple's help does not give a size for the approximate area.
How do I know an app is using location right now?
A black or white arrow appears in the status bar or Control Center while an app uses Location Services. A blue pill in the status bar means an app is using location in the background.
Can I see which apps used my camera or location last week?
Yes, with App Privacy Report on iOS 15.2 or later. It shows the past 7 days of access and network activity, but only from the moment you turn it on.
Does changing a permission delete what the app already collected?
No. It stops future access on the phone. Apple's help does not describe it removing data the app's provider already holds; check the app's privacy policy for deletion.
Can someone turn on iPhone permissions for an app from a website?
No. Apple's help says apps won't use your location until they ask and you grant permission, and those choices live in the iPhone's own Settings.
