App lock with fingerprint, PIN & voice lock. Hide photos & videos in a vault.
App Lock - Media Hider is an app lock and a private photo vault in one. Lock apps with your fingerprint, a PIN, a pattern or your own voice, and hide photos and videos where nobody else can see them. No account, no sign-up: your lock and your hidden files stay on your phone.
🔒 LOCK APPS IN ONE TAP
• Flip a switch next to any app and it asks for your lock before it opens: chats, social media, gallery, email, banking apps, Settings and more.
• PIN lock with a 4 to 6 digit password, or a pattern lock on a 3×3, 4×4 or 5×5 grid.
• Fingerprint lock, plus face unlock on phones that support it, through Android's own biometric prompt.
• A "Lock it?" prompt after every new install, so no new app stays open by mistake.
• Random keypad shuffles the digits on every lock screen, so nobody learns your PIN by watching.
• Forgot your PIN or pattern? Reset it with your own recovery question.
🎙️ VOICE LOCK: SPEAK TO UNLOCK
• Pick a secret phrase and unlock your locked apps just by saying it.
• Your PIN or pattern always works as a backup.
⏱️ RE-LOCK YOUR WAY
• Lock again immediately, after the screen turns off, or 1 or 5 minutes after you leave an app.
🖼️ HIDE PHOTOS & VIDEOS IN A VAULT
• Hide photos, videos, audio files and documents. They disappear from Gallery, Files and every other app and stay safe in your vault.
• View pictures and play videos right inside the photo vault.
• Unhide a file to put it back in your phone's storage, or delete it for good.
• Hidden files are kept in the app's private storage on your phone and are never uploaded.
📸 INTRUDER SELFIE
• Catch who tried to open your apps: after a set number of wrong attempts, the app quietly takes a front-camera photo.
• See every intruder photo with the time it was taken. The photos stay on your phone.
🎭 DISGUISE AND FAKE CRASH
• Fake crash cover: a locked app shows a fake "keeps stopping" message instead of the lock screen. Press and hold "Close app" to reveal the lock.
• Change the app icon to look like a Calculator, Calendar, Clock, Camera, Notes or Gallery icon.
• Hide in recents keeps the app's preview out of the Recents screen and blocks screenshots.
🎨 LOCK SCREEN THEMES
• Choose a wallpaper for your lock screen from nature, cars and more, and preview it before you apply it.
• Light, dark or system theme for the app.
🛡️ UNINSTALL PROTECTION
• Optional: turn it on and nobody can uninstall App Lock without your lock. Turn it off from the app any time.
✅ WORKS QUIETLY IN THE BACKGROUND
• A light protection service keeps your apps locked and starts again after a reboot.
• A simple checklist helps you allow the permissions App Lock needs.
• 10 languages: English (US and UK), Hindi, Bengali, Spanish, French, Arabic, Russian, Indonesian and Chinese (Simplified).
🔐 PRIVACY FIRST
• Your PIN and pattern are stored as salted hashes. Your voice phrase and recovery answer are protected by the Android Keystore. None of them leave your phone.
• Fingerprint and face unlock use Android's biometric prompt; the app never sees your biometric data.
• Voice lock turns what you say into text with your phone's speech recognition service; no recordings are kept.
• The app shows ads and collects anonymous usage and crash statistics to improve. You can change your ad privacy choices in Settings.
• Uninstalling the app deletes your hidden files, so unhide anything you want to keep first.
PERMISSIONS
Usage access: to know which app is open. Display over other apps: to show the lock screen. All files access: to hide and unhide your files. Camera and microphone: only for intruder selfie and voice lock, and only after you turn them on.
One applock for your apps, one vault for your photos and videos.
