🔐 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!

😵 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.)

Inactive unless someone enters the wrong PIN, ensuring minimal battery usage.
