User Guide & FAQ

To act as a "Digital Shield," the app needs deep system access. We only ask for what is strictly necessary:

• Camera: To catch the intruder.
• Overlay: To show the alarm screen on top of other apps (like the launcher).
• Usage Access: To know if someone opened a sensitive app.
• Device Admin: To detect incorrect PIN/Pattern entries for the Intruder Selfie feature.

By default, everything is on your phone. If you enable Cloud Backup, we use your own Google Drive to store encrypted evidence. This means even if your phone is stolen and wiped, you can still access the intruder photo from another device by logging into your Drive.

Android often kills background apps to save battery. For specific features like "Motion Alarm" to work reliably, you must exclude the App from Battery Optimization in your phone settings.

Unlock your phone! The app detects a successful biometric (fingerprint/face) unlock or correct PIN entry and automatically silences the alarm.
