DT2S Tap to Sleep widget

ACCESSIBILITY SERVICE API DISCLOSURE
This app uses the Accessibility Service API solely to enable the double-tap screen lock/sleep feature. The Accessibility Service is required to perform the system-level lock command. It does not collect, monitor, store, or share any personal data, screen content, keystrokes, or background interactions.

DT2S (Double Tap to Sleep) Widget is the ultimate utility solution to lock and put your device to sleep with a simple double-tap! Secure your physical power button from wear-and-tear by using fully transparent, customizable home screen widgets and a quick-settings tile.

🌟 Key Features

• Instant Double-Tap Lock: Place a widget on your home screen and double-tap it to instantly lock your phone.
• Fully Transparent Mode: Blend widgets seamlessly into your home screen background or custom wallpaper for a clean, minimalist layout.
• Premium Customizations: Style your widgets with adjustable background colors, opacity, size (12dp to 48dp), and a curated collection of modern vector icon shapes.
• Quick Settings Tile: Lock your screen directly from the system notification panel by pulling down and tapping your custom DT2S tile.
• Double-Tap Timeout Control: Customize the gesture recognition interval between 200ms and 800ms to match your double-tap speed.
• Haptic Vibration Feedback: Choose between "Soft", "Medium", and "Hard" vibration patterns for tactile feedback on locking.
• Optional Pre-Lock Ripples: Add subtle, satisfying visual ripples starting from the widget bounds before the lock triggers.

🛡️ Secure Locking Mechanisms

Choose between two highly secure lock integration options:

1. Accessibility Service (Recommended): Uses Android's modern Accessibility Framework to lock your screen safely. This method preserves your fingerprint, face unlock, and smart-lock functionality so you can unlock your device effortlessly.
2. Device Administrator (Legacy Fallback): Integrates standard system administration policy locks. Best suited for legacy devices where fingerprint credentials are not required or accessibility options are restricted.

🔋 Battery Optimized & Privacy First

• Zero Battery Drain: DT2S does not run heavy background loops or tracking services. It executes lock operations instantly and only when you tap a widget.
• No Internet Requests Needed: The widget runs completely locally. No data leaves your device, ensuring maximum privacy.
• Minimal Permissions: We believe in asking only for the permissions required to lock the screen and notify you.
