About this app

Protect your privacy and secure your sensitive data with AppLock. Easily lock any installed application on your device, ensuring that only you can access them using a secure PIN or your fingerprint.

Developed with a modern interface using Jetpack Compose, AppLock provides a smooth, battery-efficient, and lightweight security experience.

Key Features:
✅ Total Protection: Lock social media, photo galleries, messages, and banking apps.
✅ Biometric Unlock: Fast and secure access using your fingerprint (on supported devices).
✅ Secure PIN: Set a unique numeric combination for maximum security.
✅ Anti-Unlocking System: Prevents unauthorized access to protected apps by overlaying a secure lock screen immediately.
✅ Lightweight & Fast: Optimized performance that won't slow down your device.
✅ Customizable Lock Delay: Choose how long an app stays unlocked after you've entered your PIN or fingerprint. Switch between apps seamlessly without having to unlock them every single time.

Why choose AppLock?

• Prevent others from seeing your private photos and videos.
• Protect your shopping and financial apps from unauthorized use.
• Keep your data safe even if you lend your phone to someone else.

Accessibility Service API & Overlay Disclosure

AppLock: Fingerprint & PIN utilizes the Accessibility Service API and the "Display Over Other Apps" (Overlay) permission to ensure your security and privacy:

Accessibility Service: This permission is required exclusively to detect when a protected application is launched. This allows AppLock to identify the app opening and immediately trigger the lock screen.

Overlay Permission: This permission allows the lock screen to be displayed on top of the application being protected. This ensures the app's content remains hidden until the correct password or pattern is entered.

Important: We do not collect, store, or share any personal data, passwords, or usage information through these permissions. Their use is strictly limited to the locking functions requested by the user.
