Kura is a lightweight, open-source app locker designed for speed and compatibility. It allows you to protect any app on your device using your system's biometric authentication (Fingerprint/Face).
To provide a seamless locking experience, Kura requires two high-level permissions:
- Accessibility Service: Used to detect in real-time when a "locked" app is being opened. This is the most battery-efficient way to monitor app launches on Android 7+.
- Display Over Other Apps: Allows Kura to show the biometric authentication screen immediately over the target app, preventing unauthorized access to the app's content.
- Broad Compatibility: Supports devices running Android 7.0 (API 24) and above.
- Biometric Security: Leverages the official Android Biometric hardware.
- Privacy Centric: No internet access. No data collection. Just security.
- Instant Lock: High-performance detection ensures the lock screen appears before the app content is visible.
- Download the latest APK from the Releases section.
- Enable Accessibility: Go to Settings > Accessibility > Kura and toggle "On."
- Allow Overlay: When prompted, grant "Display over other apps" permission.
- Select the apps you wish to protect and you're good to go!
