AppLock Offline is a private app lock for Android that protects selected apps with a 4- or 6-digit PIN or your device’s biometrics.

Lock apps you want to keep private while keeping your protection simple, local and focused. No ads, no AppLock account, no cloud sync and no tracking.

APP LOCK WITH PIN OR BIOMETRICS

• Lock selected apps with a 4- or 6-digit PIN.
• Unlock faster with Android biometrics when available.
• Use fingerprint or face authentication where supported by your device.
• Your PIN always remains available as a fallback.
• Change your PIN whenever you need to.

PROTECT THE APPS YOU CHOOSE

Choose which apps should be protected and AppLock Offline will show its secure lock screen when they are opened.

• Protect one external app in the Free version.
• AppLock protects itself without using your Free app slot.
• AppLock Pro removes the app limit and allows unlimited protected apps.
• Stored app selections can be restored when Pro becomes active again.

FLEXIBLE RELOCK RULES

Choose when protected apps should require authentication again:

• Immediately after leaving the app.
• After 30 seconds.
• When the screen turns off.

PRIVACY-FIRST APP PROTECTION

AppLock Offline is designed to keep app protection local to your device.

• No ads.
• No AppLock account.
• No cloud sync.
• No analytics SDKs.
• No advertising trackers.
• No detailed app-opening history stored.
• Protected-app selections remain on your device.
• Biometric data stays managed by Android and your device hardware.

Android Usage Access is processed locally only to determine which app is currently open so AppLock Offline can protect the apps you selected.

Optional Faster protection uses Android Accessibility only to observe app window changes so selected apps can be detected sooner. It does not read screen text, inspect Accessibility nodes, click, type, perform gestures, or capture screenshots. The option is off until you enable it, and standard Usage Access protection remains available.

EXTRA PROTECTION

• Optional suggestions for newly installed apps.
• Optional best-effort protection for uninstall screens.
• Protection automatically resumes after supported device restarts and app updates when you previously left protection enabled.
• A visible notification shows when protection monitoring is active.
• Built-in Protection Test helps verify that your PIN and protection are working.
• Repair Protection helps restore required Android permissions when needed.

SIMPLE BY DESIGN

AppLock Offline focuses on one job: protecting your apps.

No cleaner. No browser. No photo vault. No unnecessary extras.

Lock your apps. Nothing else.
