LOCK APP - Fingerprint & Vault

🔒 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

✦ SAFE VAULT (AES-256)

• Move photos and videos into an encrypted private vault

• After 3 wrong attempts (configurable), front camera quietly snaps the person's photo with GPS and timestamp
