AirGuard - AirTag tracking protection

Protect yourself from Find My Tracking

The AirTags and other Find My devices are simple, small and perfect to track Android users! Without tracking warnings, as integrated on iOS, anyone could try to track your behavior by placing an AirTag in your jacket, backpack or car.

With AirGuard you get the anti-tracking protection you deserve! The app periodically scans your surroundings for potential tracking devices, like AirTags or other Find My devices. If a devices follows you, you will get a notification in less than an hour!

With the app you can play a sound on AirTags and find it easily. Afterward, you can view at which locations the device has tracked you.

If you no one is trying to track you, the app will never bother you.

Who are we?

We are part of the Technical University of Darmstadt in Germany. This project is part of a scientific research from the Secure Mobile Networking Lab. Our goal is to protect privacy and to find out how many people are opposed to tracking. In this app you can voluntarily participate in a research study that will share anonymized data with us.

This app will never get monetized by showing ads, in-app purchases or anything else.

  • 1. [Bug] Automatic background scan is not working

    Despite having the app excempted from battery optimization, the background scan is not working. Every time when opening it the "Last scan" field is from I have last opened the app.

    I use LineageOS 18.1 (Android 11) and would be happy to provide any debugging information (adb logcat, whatnot) as needed

  • 2. [Question] What does the 'last scan' entry mean?

    I very appreciate your app, thanks for the possibility to get notified about possible tracking devices. What I don't understand is the 'last scan' section on the status screen, what does that mean? My 'last scan' is often some hours ago, in worst cases some days. I did exclude the app from battery saving and use a phone without google services (microG installed, but only partly activated).

  • 3. Add ability to give a device a friendly label

    Some devices move with me but are known. Examples may include a tag owned by myself or a known trusted associate. I would rather label those devices instead of just ignoring them, so I can remember why they are ignored.

    Great software by the way, thanks for all your hard work.

  • 4. Unknown devices

    Hello, the app finds devices with different mac addresses every 15 minutes on the map and in the manual scan, but in the same place. Possibly mac books. What devices could that be? If there are no trackers, can you exclude them from the search?

  • 5. FP3: after update to 1.1.0 history is lost and no new findings (bug or feature?)

    After upgrading to 1.1.0 the history of found devices is lost, but also it does not find devices 1.0.6 (still) does find.

    FP3 with LineageOS 18.1.

    What else is helpful for you?

  • 6. [Suggestion] Add ability to "whitelist" devices.

    You should be able to whitelist devices, so that the app will not warn you every time you enter it. For example, I own a tile, and I keep it in my wallet, and even though I've muted it, the app shows that I am unsafe.

    Thanks, SteadyStatus21

  • 7. Settings Translation Error: Reverse Meaning - Use Low Energy Scan

    Description

    The "Use Low Energy Scan" setting is described differently in German and English

    Statement of the translations:

    EN: This option is required to detect all devices DE: If this option is enabled, some devices may not be detected

    LowEnergySettingEN

    LowEnergySettingDE "This may result in some devices not being recognized." Translation by DeepL.com

    Version affected

    F-Droid: 1.2 (I could not install versions 1.1.0 and 1.1.0 due to an unknown error)

  • 8. Improve English "notification_help" string

    Changes "Make sure that you don’t move to a safe place before you have deactivated the tracker." to "Make sure that you don’t move to another location before deactivating the tracker."

    Telling users to avoid going to "a safe place" seems to be a mistranslation from the German string "Stelle sicher, dass du dich nicht an einen anderen Ort begibst bevor du den Tracker gefunden hast". "Deactivating" is a shorter way to say "you have deactivated" in the sentence.

    Hi I’ve version 1.0.4 installed and It found two air tags the other day but I never got a notification they were detected. Is there something I’m missing or do notifications trigger under certain situations?

    I’m running it on a Pixel 2XL running CalyxOS (android 11).

    Please let me know if any additional information would be helpful.

  • 11. Correct typos, clarified wording in strings.xml

    I cleaned up typos and clarified the wording of various strings in strings.xml. (Most memorable is separating "Find My", capitalizing Bluetooth, and replacing "Low Power" with "Low Energy" - even though power is actually more accurate from an electrical engineering perspective.) Feel free to alter my edits as desired.

  • 12. Incorrect instructions on finding tracker.

    There is a typo in the instructions on what to do if you're being tracked. It says "do not move to a safe location before deactivating" I presume this should say "move to a safe location"

  • 13. Adjust the wording of the "no results" text to be more correct.

    name="scan_result_no_devices">No tracking devices were found. You\'re safe!\nWe only scan for Apple Find My Trackers (AirTags) and Tile.

    As of 1.2 release notes other items like chipolo can be scanned for, but this string explicitly says only Apple and Tile.

  • 15. Give further hints for potential reasons on false alarms regarding traveling

    Hi!

    I recently got an AirTag warning on a 3 hour trip on a long distance train, I traveled almost 500km with.

    For me that was great, as I had a real world example for the app working. Also, because I got no further warnings after the train ride, I am quite sure, that this was not a malicious tracking attack on me, but a fellow traveler sitting nearby probably had an active airtag for her or his own purposes.

    As an alarm warning can be a little bit intimidating in the moment when I receive it, making the connection, that it was during a train journey together with strangers, took a few moments. Maybe a hint to this idea could be incorporated into the alarm message or the guidelines regarding "false alarms"?

    Although we are after two years of pandemic only getting used to it, but I guess long distance travel on busses, trains and maybe planes would be a usual reason for triggering false alarms?
