A production-quality, high-performance, and privacy-first Android utility designed to lock the device screen instantly with a single tap. It functions as a lightweight software replacement for the physical power button, keeping resource utilization virtually zero.

🚀 Core Features Zero-UI Execution: If either locking method is configured, launching the app locks the screen instantly with no UI, animations, loading screens, or layouts. The application finishes itself within milliseconds. Dual Lock Engine: Biometric-Friendly Lock (Accessibility): Locks the screen while keeping Fingerprint & Face Unlock active. (Recommended) Standard Admin Lock (Device Administrator): Standard platform locking. (Forces PIN/Password on the next unlock due to Android OS security policies). Launcher Shortcut (Long-press): Static shortcut ("Lock Screen") visible when long-pressing the app icon. Can be dragged onto the home screen for layout-less instant locking. 1x1 Home Screen Widget: A premium, slate-dark gradient circular widget with high contrast and balanced spacing, triggering the lock on tap. Quick Settings Tile: A "Lock Screen" tile that fits directly into the notification tray shortcuts, built with API 34+ compatible intent collapsing. Extremely Lightweight: Built using vanilla Android APIs and Kotlin with minimal dependencies. The compiled release APK size is under 50KB. Offline & Private: Absolutely no network permissions requested. Zero database initializations, background trackers, analytics, telemetry, or advertisements.
