You can stop most app tracking on Android in about ten minutes. Delete your advertising ID, switch off personalised ads, audit app permissions, and turn off precise location and background activity. On Android 15, move data-hungry apps into Private Space. No single setting blocks everything, but these eight changes together cut tracking sharply.
What app tracking actually means
Many apps contain third party tracker code that collects data in the background, even when the app is closed. It records your location history, your device model, which apps you have installed, and when you open them. Ad networks combine these signals into a profile of your habits and movements.
The worst offenders are often ordinary apps. Free games, weather apps, torch apps and shopping apps sell advertising data to pay their bills. Research published in the ACM Digital Library found that more than half of the apps it tested still contacted third party tracking domains after tracking permissions had been revoked. One setting is never enough.
First, run the 2 minute Privacy Dashboard check
Before changing anything, find out which apps are already watching you. Android has a built in Privacy Dashboard that shows which apps used your location, microphone or camera in the last 24 hours. Open Settings, tap Security and privacy, then tap Privacy Dashboard. Any app that used your location or microphone overnight deserves a closer look. Also watch for the small green dot in the top corner of your screen. It appears whenever your microphone or camera is active.
1. Delete or reset your advertising ID
Your advertising ID is a unique identifier that ad networks use to link your behaviour across different apps. Deleting it breaks that link and makes it much harder for advertisers to build a profile of you. Open Settings, tap Privacy, then tap Ads. Tap Delete advertising ID and confirm. If your phone only offers Reset advertising ID, tap that instead. Resetting gives you a fresh identifier.
One change arrived in 2026. On newer Google Pixel phones, the on device advertising ID setting has been removed from system settings. If you cannot find the Ads menu, the control has moved online, and step 2 covers it.
2. Switch off personalised ads in your Google account
Google has moved most ad control online, so a single tap on your phone is no longer enough. Open a browser and sign in at myaccount.google.com. Go to Data and privacy, scroll to Personalised ads, open My Ad Centre, and switch personalised ads off.
This stops Google using your activity to tailor adverts to you. You will still see ads, but they will be generic rather than based on your behaviour. If you also use AI chatbots, remember they collect conversation data too, so read our guide on how AI chatbots handle your data before sharing anything sensitive with them.
3. Audit your app permissions
Permissions are the biggest hidden source of tracking. Ask a simple question for each one: does this app need this permission to do its job? A notes app does not need your location, and a torch app does not need your microphone.
Open Settings, tap Security and privacy, then tap Privacy and Permission Manager. Work through Location, Camera, Microphone and Contacts one by one. Tap any app that should not be there and choose Don’t allow. If an app needs a permission sometimes, choose Allow only while using the app instead.
Be strict with Contacts. Access to your address book shares the phone numbers and addresses of your friends and family with the app developer.
4. Turn precise location into approximate location
A weather app needs your town, not your street. Android lets you give apps an approximate location instead of a precise one. Open Settings, tap Location, then tap App permissions. Choose an app and turn off Use precise location. Keep precise location on only for maps, sat nav and ride hailing.
5. Stop apps running in the background
Background activity is how trackers send your data home while your phone sits idle. Restricting it is one of the most effective single changes you can make.
Open Settings, then tap Apps. Choose a data hungry app, such as a free game or a social app. Tap Battery, then App battery usage, and select Restricted, or switch off Allow background use. On Samsung phones, go to Settings, then Battery, then Background usage limits, and switch on Put unused apps to sleep.
6. Turn off Bluetooth and nearby device scanning
Even with GPS switched off, your phone can still be tracked. Bluetooth scanning and Wi-Fi scanning let apps work out your location from nearby beacons and routers. Retailers use this trick to track shoppers inside stores.
Open Settings, tap Location, then tap Location services. Switch off Bluetooth scanning and Wi-Fi scanning. You can still use Bluetooth headphones and Wi-Fi normally.
7. Isolate data hungry apps with Android 15 Private Space
This is the step most guides skip, and it is the strongest one. Android 15 introduced Private Space, a separate locked area for apps you do not fully trust. Apps inside it cannot run in the background, cannot collect data while the space is locked, and stay hidden from your app drawer.
Open Settings, tap Security and privacy, then tap Private Space and follow the setup steps. Choose a separate lock such as a PIN or fingerprint. Then move your data hungry apps into it. Good candidates in the UK include free games, shopping apps, social apps and weather apps that ask for more permissions than they need.
On Samsung phones, the equivalent feature is called Secure Folder and works in a similar way. If your phone has not received Android 15 yet, steps 1 to 6 above still cover most of the risk.
8. Block trackers across the whole phone
If you would rather not change every setting by hand, block trackers at the network level instead. The DuckDuckGo app includes App Tracking Protection. Switch it on and it blocks connections to known tracking networks before the data leaves your phone. You can also use a private DNS service. Go to Settings, then Network and internet, then Private DNS, and enter the hostname of a filtering DNS provider such as AdGuard DNS. Your phone will then filter tracking requests from every app. Neither option needs technical skill or root access.
What these settings cannot stop
Honesty matters here. These eight steps cut tracking sharply, but they cannot remove it completely. Apps still need some data to work. A maps app cannot navigate without your location. Services you are signed into, such as your Google account, can still link activity to your account. And as the ACM study showed, some trackers keep phoning home even after permissions are revoked, which is why combining several defences matters more than any single one.
Do not overdo it either. Blocking permissions too aggressively can break apps. If an app stops working after a change, simply re-grant the one permission it needs and leave the rest revoked.
Frequently asked questions
Can I stop all tracking on Android?
No, not completely. You can stop most cross app tracking and ad profiling, but apps still collect some first party data to function. The goal is to cut tracking to a minimum, not to reach zero.
Does deleting the advertising ID stop adverts?
No. You will still see adverts, but they will be generic instead of personalised. Deleting the ID stops advertisers linking your behaviour across apps into one profile.
Will these settings break my apps?
Only if you revoke a permission an app genuinely needs. If something stops working, re-grant that one permission and test again.
Is Private Space available on my phone?
Private Space needs Android 15 or later, which most Pixel phones and recent phones from Samsung, Nothing and other major brands now have. Samsung phones also offer Secure Folder, which does a similar job on older versions.
Conclusion
App tracking on Android feels invisible because it is designed to be. Take ten minutes, work through the eight settings in this guide, and repeat the Privacy Dashboard check once a month. Protecting the accounts behind the apps matters too, so consider a password manager for the whole family to keep your logins safe if any single app is ever breached.
