About this app
🔒 LOCK APP — the simple, modern app lock for Android.
Keep WhatsApp, Instagram, Gallery, banking apps, and chats private. Lock any app with a PIN, pattern, or fingerprint — and hide your sensitive photos in an encrypted vault that's invisible to your gallery.
Built clean, modern, and 100% on-device. No accounts. No ads. Nothing leaves your phone.
✦ LOCK ANY APP
• PIN (4 or 6 digit), 3×3 pattern, or fingerprint
• Random keypad — defeat shoulder-surfing
• Hide pattern draw path — strangers can't copy your gesture
• Auto-lock newly installed apps (optional)
✦ SAFE VAULT (AES-256)
• Move photos and videos into an encrypted private vault
• Hidden from gallery and file manager
• One-tap import from your photo library
✦ INTRUDER SELFIE
• After 3 wrong attempts (configurable), front camera quietly snaps the person's photo with GPS and timestamp
• Review every intruder in the in-app log
✦ DISGUISE ICON
• Hide LOCK APP behind Calculator, Compass, Weather, Clock, or Notes
• Peeping eyes never know it's an app lock
✦ AUTO-LOCK BY SCHEDULE
• Lock Instagram during work hours, unlock evenings
• Multiple schedules, any days, any time window
✦ QR-CODE PIN BACKUP
• Forgot your PIN? Recover with a QR code, security question, or email — your call
✦ PRIVACY DASHBOARD
• See unlocks, blocked attempts, intruder captures
• Weekly stats so you know your phone's safe
✦ MATERIAL YOU + MODERN POLISH
• Dynamic color matches your wallpaper (Android 12+)
• 6 hand-tuned themes • Dark mode
✦ 100% ON-DEVICE
• Zero cloud, zero servers, zero tracking, no ads
PERMISSIONS WE NEED
• Usage Access — to know which app you opened so we can lock it
• Display over other apps — to show the lock screen on top
• Camera — only for intruder selfies (optional)
• Location — only to tag intruder selfies (optional)
• Notifications — to keep the lock service running
Made for people who want privacy without bloat.
