Neruppu

Neruppu is a modern, offline-first physical security monitoring app that uses your device's sensors to detect and record security events.

Features:

• Camera motion detection (front and back cameras)

• Microphone audio monitoring with automatic recording on noise bursts

• Accelerometer movement/vibration detection

• Ambient light change detection

• Optional Matrix remote alerts

• All data stored locally - no cloud required

The app runs as a foreground service ensuring continuous monitoring while providing optional encrypted remote notifications via Matrix when security events are detected.

Built with privacy and security in mind - all logs and media remain on your device unless you explicitly configure remote alerts.
