About this app

🔐 CrookCatcher: Your Personal Phone Security Guard
Worried about phone theft or snooping? Me too, that's why I built this app. CrookCatcher protects your phone by capturing photos whenever someone enters the wrong password, PIN, or pattern. Then, it emails you with intruder photos, GPS location, and estimated address. But CrookCatcher can do lots more!

🚀 Upgrade to PRO for Advanced Security

🔍 Record Intruders in Detail

🚨 Advanced App Security

🔐 Catch Even After Unlock
Break-in detection captures a photo if the intruder successfully guesses your password after failed attempts.

😵 Protection Against Shutdown Attempts
CrookCatcher can block the power menu, quick settings, and notification shade to capture evidence when thieves try to turn off your phone or enable airplane mode. CrookCatcher uses the accessibility permission to detect these elements on the lock screen. (Experimental feature, may not work on all devices.)

🔋 Battery-Friendly
Inactive unless someone enters the wrong PIN, ensuring minimal battery usage.

❗ Important Notes
- Unlock your phone once after rebooting to re-enable CrookCatcher.
- Not compatible with pop-up cameras or fingerprint errors.
- On Android 13+, a system notification appears when the camera is in use.
- Uses Device Administrator permission to monitor unlock attempts securely.

Awesome app. Loads of functions and options. You can write whatever you want to flash up when it's taken an intruders photo, you can take a video of them with sound, add location settings etc etc. I've been through the Terms of Use and the Privacy Policy and they're both concise and easy to read, there's no hidden privacy clauses or data manipulation. Recommend this app to anyone who is worried about their phone falling into the wrong hands.

Every time I receive a phone call and answer it directly from the lock screen, after the call ends, CrookCatcher gets triggered automatically. I keep receiving photos and videos as if an unauthorized unlock attempt was made. The notification shows “Detected Notification Shade”, even though I have only interacted with the incoming call. Please add extra option for not capturing photo videos during incoming calls from the lock screen.
