About this app

AppLocker is an app lock for Android. Lock chats, photos or banking behind a PIN or pattern. Free plan: up to 3 apps. Pro adds fingerprint unlock and Intruder Selfies.

Free plan
• Lock up to 3 apps with a PIN or a pattern
• Automatic re-lock: an app locks again shortly after you leave it, and always when the screen turns off
• AppLocker locks itself too, so nobody else can change your settings
• Uninstall Protection: stops others from uninstalling AppLocker
• Ask to lock new apps: get a prompt whenever you install an app
• After several wrong PINs in a row, PIN entry pauses for a short time
• The free plan shows ads

AppLocker Pro
AppLocker Pro is a monthly subscription. Eligible new subscribers start with a free trial, and you can cancel anytime in Google Play. Pro includes:
• Unlimited app locks
• No ads
• Fingerprint unlock
• Intruder Selfies and Break-in Alerts: a front-camera photo and a record of every failed unlock attempt
• Break-in evidence+: see the code an intruder tried and export photo evidence
• Kids Mode: one tap locks every app except the ones you allow, handy before you hand your phone to a child
• Lock system screens: Settings, Play Store and the app installer ask for your PIN
• Hide notification content: previews from locked apps stay hidden until you unlock
• Scrambled keypad: the digits shuffle on every lock screen, so nobody learns your PIN by watching
• Per-app re-lock timing: immediately, after 30 seconds or when the screen turns off
• Quick Settings pause: pause protection from Quick Settings with your PIN; it switches back on when the screen turns off
• Screen-time stats: see how often each app was opened today

Permissions, explained
• Usage Access: lets AppLocker see which app is opening so it can lock it. Pro's screen-time stats also use it to count today's app opens
• Display over other apps: shows the lock screen on top of a locked app
• AppLocker does not use Accessibility services
• Battery: during setup AppLocker asks to run without battery restrictions, because some phones stop background apps and that would switch your locks off
• Only when you turn the feature on: camera (Intruder Selfies), notification access (Hide notification content) and device admin (Uninstall Protection only)

Languages and requirements
• Available in 9 languages: English, Arabic, German, Spanish, French, Hindi, Portuguese, Russian and Chinese
• Requires Android 7.0 or later
