🔐 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!

🌟 Trusted by Millions
- 8+ million downloads
- 500M+ intruder photos captured in 190+ countries since 2014

🥳 Free Features everyone needs
✅ Capture intruder photos
✅ Detect GPS location
✅ Send alert emails

🚀 Upgrade to PRO for Advanced Security

🔍 Record Intruders in Detail
- Capture VIDEOS with sound for clear evidence of intruders.
- Use the back-facing camera for environment details.
- Auto-upload photos/videos to Google Drive for access on any device.

🎭 Outsmart Thieves
- Display a fake home screen to trick intruders.
- Show a custom lock screen message warning thieves.

🚨 Advanced App Security
- Hide the app with a disguised icon and name.
- Customize alert email subjects and hide notifications.
- Lock access to CrookCatcher with a pattern code.

🔐 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.
