IntruderSelfie silently snaps a front-camera photo every time the screen is unlocked with a precise timestamp.

Key points

Runs as a lightweight foreground service after device boot – no need to keep the app open.
Works offline – no internet, ads, or third-party libraries.
Uses only the minimum Android permissions: Camera for photos, Foreground-Service to stay alive, Boot-Completed to start after reboot, and Storage to save images locally.
Compatible with Android 8 → 14 (API 26-35).
