App Lock for Android

Brief summary

App Lock, created by Little Angel, adds a secondary barrier to prevent others from opening your apps and accessing private information on an Android device. It’s designed to be simple to set up while offering multiple authentication choices for different comfort levels.

Available unlocking methods

• PIN code entry
• Pattern-based unlock
• Biometric/fingerprint verification

Pick the unlocking style that fits your routine, or combine methods for stronger protection.

What you can secure

• Photo and video galleries
• Individual apps and system utilities
• Contacts, notes, and other personal files

You can apply protection to a broad range of apps and data so sensitive items remain private.

Resetting access if you forget

If you lose your PIN or forget your pattern, the app provides a recovery path: answer your preset security questions to regain access. This makes it easier to recover without uninstalling or losing data.

Permissions the app requests

• Permission to run a foreground service
• Access to fingerprint hardware
• Ability to check package usage statistics and certain protected permissions
• Permission to query all installed packages
• Receive notification when the device finishes booting

These permissions enable features like detecting app launches, supporting biometric unlock, and automatically reapplying locks after a restart.
