# AirGuard (open-source privacy app)

> AirGuard is a free, open-source privacy app for Android. AirGuard detects trackers that are used for stalking and warns you. It has 2,538 GitHub stars and is released under the Apache-2.0 license, and you can install it from F-Droid and Google Play.

With AirGuard, you get the anti-stalking protection you deserve! The app scans your surroundings in the background to detect trackers like AirTags, Samsung SmartTags, or Google Find My Device trackers. If a tracker is following you, you will receive an instant notification. These trackers are often no larger than a coin and are unfortunately misused to secretly track people. Since each tracker works differently, you would typically need multiple apps to detect unwanted tracking. AirGuard combines the detection of various trackers into a single app – keeping you protected with ease.
