Secure your sensitive apps with powerful biometric protection using AppLock!

AppLock is a modern, open-source privacy tool designed to keep your sensitive apps safe. With a beautiful Material 3 Expressive interface and robust biometric security, AppLock ensures your data stays private — always on your device, never in the cloud.

Features:

Material You Design: Seamlessly adapts to your system theme
Biometric Unlock: Use fingerprint or PIN for fast, secure access
Anti-uninstall: Prevents unauthorized removal
Unlock Timer: Optional timer to keep apps unlocked for fixed time period after unlocking
No Root required: Works on all devices without root access
One-tap protection: Lock any app instantly
Real-time monitoring: Protects apps as they launch
100% offline: No ads, no trackers, no data collection

Perfect for:

Privacy-conscious users wanting to secure sensitive apps
Securing banking, messaging, and social apps
Parents restricting access for children
Professionals protecting work apps

App Lock is designed to be lightweight and efficient, with minimal battery impact. It runs entirely offline, ensuring your data remains private and secure.

Built with Jetpack Compose and Material 3 for a smooth, intuitive experience. AppLock is free, open-source, and respects your privacy — always.

Download Source Issues ChangeLog

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
