PrivateLock

Private Lock enhances your mobile device's physical security and safeguards personal information by automatically locking your phone upon sudden, forceful movements, like being snatched or dropped. This provides immediate **data protection**. As an **open-source Android application**, its code is reviewable, fostering transparency. Importantly, Private Lock is **completely free from advertisements and tracking mechanisms**, highlighting its commitment to user privacy. The app monitors your device's accelerometer. If a movement threshold is breached, it instantly locks the screen, helping **prevent unauthorized access**. Key features include: * **Customizable Sensitivity**: Fine-tune lock sensitivity with a visual animation. * **Persistent Monitoring**: A notification shows when the service is active. * **Autostart Option**: Configure the app to start on device boot. * **User-Friendly Controls**: Manage via a home screen widget or pause the service temporarily. Device Admin permission is required for screen locking. Other permissions like `RECEIVE_BOOT_COMPLETED` support autostart, and `FOREGROUND_SERVICE` ensures reliable background operation. Developers note a standard Android security behavior: a PIN is required to unlock after the app triggers a lock, even with biometrics enabled. For those seeking a simple, **privacy-respecting tool** for physical phone security, Private Lock is an effective solution.
