Are Mobile Apps Tracking Your Every Move? How to Check
Many mobile apps can track your location and activity, but only to the extent your phone's permissions allow. You can see which apps have location access in your privacy settings, switch most to "while using" or off, reset your advertising identifier and delete apps that ask for more data than they need. A ten-minute review cuts most unnecessary tracking.
Key takeaways
- Location, contacts, photos and microphone access are all controlled by app permissions.
- Background location access is the setting most worth reviewing.
- Advertising identifiers let companies link your activity across apps; you can reset or limit them.
- Work phones may have additional monitoring set by an employer, governed by company policy.
- Review permissions after installs and major operating system updates.
How do apps track you?
The Federal Trade Commission explains that apps may ask for access to device information such as location, contacts or photos, and that companies may track activity using a unique advertising identifier on your phone. Tracking can be first-party, by the app you are using, or third-party, by other companies the app allows to collect data. Companies can also link activity across your phone and laptop.
The main tracking channels are:
| Channel | What it reveals | Where to control it |
|---|---|---|
| Location permission | Where you are and where you go | Privacy or location settings, per app |
| Advertising identifier | Activity linked across apps for ads | Privacy or ads settings |
| Account sign-in | Activity tied to your identity | Each app's account privacy settings |
| Photo metadata | Where a photo was taken | Camera and photo sharing settings |
| Bluetooth and Wi-Fi scanning | Nearby devices and approximate location | Connectivity and location settings |
Check location access on your phone
On iPhone
Go to Settings, then Privacy and Security, then Location Services. Apple's support documentation explains that an app granted "While In Use" can access location while it is open, and that your iPhone periodically reminds you when an app is using location in the background. A blue indicator in the status bar shows background location use, and an arrow icon appears when Location Services is active for an app. System Services, at the bottom of the list, lets you control location use by built-in features individually.
On Android
Open Settings and look for Location, then App location permissions. Apps are grouped by whether they are allowed all the time, only while in use, or not allowed. Wording varies by manufacturer and Android version.
What to change
- Set most apps to "while using" or "ask next time."
- Reserve "always" for apps that clearly need it, such as navigation you rely on.
- Turn off precise location for apps that only need your city, like weather.
- Delete apps you no longer use rather than leaving permissions in place.
Limit cross-app tracking and ad profiling
The FTC recommends reviewing app permissions, turning off ones an app does not need and deleting apps that request too many. It also notes you can delete or reset advertising identifiers and opt out of personalized ads from your phone's operating system maker on each device. On iPhone, you can refuse app requests to track you across other companies' apps. On Android, the ads settings let you delete or reset the advertising ID.
Also check social media and shopping apps' own privacy settings, since activity tied to your account is controlled there rather than in the phone's settings.
What about tracking on work phones?
Employer-managed phones and apps are a separate case. Companies may use location features in time clock or field service apps, often limited to clock-in events or geofenced job sites. Our article asking whether Workday tracks employee location at check-in and out explains how one common system handles it, and our guide on using geofencing to verify field sales visits shows how employers can limit collection to what the job requires. Employers should publish a clear policy, collect only what they need and explain how long location data is stored and who can see it, as covered in our piece on managing employee data privacy.
Frequently Asked Questions
Can apps track my location when they are closed?
Yes, if you have granted background or "always" location access. Apps with "while using" permission can only access location while open or actively in use. Check your location settings for apps set to always, and change them unless the feature truly requires it. Both iPhone and Android show reminders or indicators when location is used in the background.
Does turning off location services stop all tracking?
No. It stops apps from using GPS and related location features, but apps can still collect activity data, account information and advertising identifiers, and networks can estimate location by other means. Combine location controls with advertising settings, app privacy settings and deleting unneeded apps for broader protection. Emergency services location features may also work differently.
Should I worry about apps on my work phone?
Work phones are typically managed under your employer's policy, which may allow certain monitoring of company apps and data. Ask HR or IT for the written policy describing what is collected, when and why. Keep personal activity on a personal device where possible, and raise concerns through the channels your employer provides.
Next steps
- Open your location settings and change any unnecessary "always" permissions.
