Understand tracking in your apps.
Discover the tracking software in your apps, understand the companies behind it, and take control on Android.

One project, two ways to investigate tracking.
Android app
Monitor and block on your device.
TrackerControl uses Android's VPN functionality to inspect network traffic locally. It needs no root and sends no personal data to an external server by default.
- See tracking companies, destinations and countries in real time.
- Block trackers and ads, with selectable blocking modes.
- Inspect tracker libraries in app code and optionally use Secure DNS or remote VPN routing.
TrackerControl Slim is the feature-reduced Google Play version with Minimal blocking mode.
iOS app reports
Identify embedded SDK signatures.
The iOS research website shows which tracking software is embedded in an app and the companies behind recognised signatures.
- Explore app reports collected from the iOS App Store.
- Learn which SDKs and trackers an app contains.
- Read the method and limits behind each report.
Reports identify embedded software. They do not block traffic or establish that transfers were observed.
Method
Evidence from code and connections.
Android combines DNS-based network analysis with tracker-library analysis. Network results show actual destinations contacted while an app runs; code results show software that may be present without being activated.
Both approaches make the companies and purposes behind tracking easier to understand, while keeping the limits of each kind of evidence visible.
Android privacy by design
Analysis stays close to the user.
Android TrackerControl processes monitored traffic on your device and does not intercept SSL/TLS connections. Optional remote VPN routing changes where allowed traffic exits; it is clearly separate from the on-device analysis.
