Device Privacy Protector

Development status:
This app represents an earlier phase of our work.
It remains available as-is, but active development is now focused on newer system-level experiences.

Device Privacy Protector continues to function normally for existing users.


About Device Privacy Protector
Device Privacy Protector uses your device’s built-in motion sensors to help lock your phone automatically based on movement.

The app runs in the background and monitors motion intensity to trigger a device lock when user-defined thresholds are exceeded.


How it works
Most Android devices include an accelerometer sensor.
Device Privacy Protector monitors motion patterns and reacts when sudden or unusual movement is detected, based on the sensitivity you configure.

This can be useful in situations where you want your device to lock automatically without pressing the power button.


Key features

✅ Automatic device locking based on motion
Locks the phone when sudden movement exceeds the configured sensitivity threshold.

✅ Shake-to-lock
Allows you to lock your device by gently shaking it, reducing frequent use of the power button.

✅ Drop alert
Provides vibration or sound alerts if the phone is dropped or falls unexpectedly.

✅ Adjustable sensitivity
Set your preferred motion threshold using a visual reference animation.


Important notes
• Continuous sensor usage may impact battery life on some devices
• Effectiveness depends on device sensors and manufacturer behavior
• The app requires necessary device permissions to function correctly
• Results may vary depending on usage and environment
