Protection Against Shutdown

CrookCatcher can block the power menu, quick settings, and notification shade, so it keeps capturing evidence when someone tries to turn off your phone or enable airplane mode. This feature uses the Android Accessibility API to detect system UI elements on the lock screen. Keep in mind this is an experimental feature and may not work on every device.

Battery Friendly by Design

CrookCatcher activates only on failed unlock attempts. That smart design keeps battery usage minimal, so you get powerful protection without draining your phone.
