Accessibility Service API Disclosure: Zen Launcher utilizes the Android Accessibility Service API mainly to provide the "Screen Off" functionality. This allows you to lock your device screen using gestures (such as a double-tap) or the proximity sensor.

Purpose: The service is used exclusively to perform the system lock action (GLOBAL_ACTION_LOCK_SCREEN). This is a convenience feature intended to reduce usage of the physical power button.
Data Privacy: Zen Launcher does not collect, monitor, store, or transmit any personal or sensitive user data through the Accessibility Service API.
User Control: Usage of this service is completely optional. It can be enabled or disabled at any time in your device's Accessibility Settings. If disabled, the screen lock gestures will not function, but all other app features will remain available.
