Lockify Features

Core Protection Features

The foundation of Lockify's security system.

App Lock Protection

Select any installed app to protect. Lockify intercepts app launches and shows a secure lock screen before granting access. Works reliably across app switches, recents, and device restarts.

PIN Support

Set a numeric PIN of 4 or more digits. The PIN entry screen is smooth, responsive, and designed for quick, accurate input on all screen sizes.

Pattern Lock

Draw a custom pattern to unlock your apps. The pattern lock is intuitive, supports minimum 4-dot patterns, and provides haptic feedback for a satisfying experience.

Biometric Authentication

Use your fingerprint or face recognition to unlock apps instantly. Biometric auth is optional and falls back to PIN/pattern if unavailable or disabled.

Anti-Uninstall Protection

Prevent unauthorized removal of Lockify using Android's Device Administrator permission. Combined with Accessibility Service monitoring, it blocks attempts to disable protection.

Forgot Password Recovery

Forgot your Lockify password? Verify your identity using your phone's own device lock (PIN, pattern, password, or biometric) and securely reset your Lockify credentials — no data loss.

Security & Reliability

Lockify is built to stay secure even in edge cases.

Reboot Persistence

Protection automatically restores after device restart. Lockify starts on boot and resumes guarding your apps without any manual action.

Unlock Time Duration

Configure how long an app stays unlocked after authentication. Options range from immediate re-lock to several minutes, giving you flexibility without sacrificing security.

Trigger Exclusions

Exclude specific apps from triggering the lock screen. Useful for apps that frequently switch context, like launchers or system utilities.

Auto Unlock on Screen Off

Optionally re-lock apps when the screen turns off, ensuring protection is always active when you put your phone down.

Secure Credential Storage

Credentials are stored securely using Android's SharedPreferences. No plain-text storage, no cloud sync, no external access.

No Data Collection

Lockify collects zero personal data. No analytics, no crash reporting to external servers, no account required. Your privacy is absolute.

Advanced Privacy & Security

New in v1.1.0 — deeper protection, more control. (Upcoming)

Hidden Vault

Encrypt photos, videos, and files with AES-256-GCM using a hardware-backed key from the Android KeyStore. Files are streamed, so even large media stays fast and private.

Scheduled Locking

Automatically lock selected apps by time of day and day of week — perfect for study, work, or bedtime routines.

Intruder Detection

Silently capture a front-camera photo after repeated failed unlocks. Photos are encrypted and stored on your device only — never uploaded anywhere.

Location & Wi-Fi Rules

Relax locking automatically on trusted Wi-Fi networks or inside trusted places, and tighten it everywhere else.

Notification Privacy

Hide sensitive notification content from locked apps, replacing previews with a generic message on the lock screen and shade.

Usage Statistics

See which apps you use most over the last 7 days with clean, on-device charts — no tracking, no cloud.

Profiles & Child Mode

Switch between lock profiles — Work, Personal, Kids — each with its own PIN. Child mode locks everything except a whitelist.

Encrypted Backup & Restore

Export a password-protected backup of your lock configuration (PBKDF2 + AES-256) and restore it on any device.

Brute-Force Protection

An escalating cooldown after repeated wrong attempts (3 → 30s, 5 → 2m, 10 → 10m) stops guess-and-retry attacks.

Scrambled Keypad

Randomise the PIN keypad layout to defeat shoulder-surfing, with a wrong-PIN shake and configurable PIN length.

Quick Tile, Widget & Shake-to-Lock

Re-lock everything instantly from a Quick Settings tile, a home-screen widget, or a quick shake of your phone.

Performance & Smoothness

Designed to feel premium on every device.

Zero-Lag Lock Screen

The lock screen overlay appears instantly when a protected app is opened — no delay, no stutter, no missed triggers.

Lightweight Background Service

Lockify's background service is optimized for minimal CPU and memory usage. It won't slow down your device or drain your battery.

Smooth UI on All Screens

Fully responsive design that adapts to phones, tablets, portrait and landscape orientations — always clean and usable.
