App Lock & Privacy Secure Apps

F1Mate Apps

About this app

App Lock & Privacy keeps your private apps private. Lock chats, photos, email, banking, or any other app with your phone's screen lock, a separate App PIN, an App password, or your fingerprint. When someone opens a locked app, they see a lock screen instead of your content.

100% free, forever. No ads, no in-app purchases, no premium version: every feature is free for everyone.

★ LOCK ANY APP
• See all your installed apps in one list, with locked apps shown at the top
• Tap the lock icon to lock or unlock an app
• Find apps fast with search and the A–Z side scroller
• Every lock or unlock change is confirmed with your PIN, password or fingerprint

★ UNLOCK YOUR WAY
• Phone screen lock: use the PIN, pattern, password or fingerprint you already use on your phone
• App PIN: a separate 4–8 digit PIN just for locked apps
• App password: a separate password just for locked apps
• Fingerprint: unlock with a touch when using an App PIN or password
• Forgot your App PIN? Verify with your phone's screen lock and set a new one

★ SMART AUTO-LOCK
• Choose when an app locks again after you leave it: immediately, after 2, 5, or 10 minutes
• Locking your phone or turning off the screen locks every app straight away
• Too many wrong attempts pause unlocking for 30 seconds

★ PROTECT APP LOCK ITSELF
• Ask for unlock every time App Lock is opened, so no one else can change your locks
• Optional uninstall protection stops others from removing App Lock to get around your locks

★ ALWAYS FREE, NO ADS
• Completely free, with no hidden costs and no subscriptions
• No ads, ever: nothing pops up or gets in your way
• All features are unlocked for everyone

★ LIGHT AND PRIVATE
• Runs quietly in the background and uses very little memory and battery
• Starts automatically after your phone restarts
• Dark theme, also used on the lock screen
• No account and no tracking
• Your PIN and password are stored only on your phone, as a secure one-way hash. Nothing leaves your device.

★ PERMISSIONS WE ASK FOR, AND WHY
• Usage access: to know which app you open, so locked apps can be protected
• Display over other apps: to show the lock screen on top of a locked app
• Run in background (battery optimisation): so Android doesn't stop the lock from working
• Notifications: shows a small, silent status notification while protection is on
• Device admin (optional): only used for uninstall protection. App Lock uses no other device admin powers, and you can turn it off at any time in Settings.

App Lock & Privacy does not read your messages, photos, or anything inside your apps. It only checks which app is on screen.
