★ MANDATORY POLICY & PERMISSIONS DISCLOSURE

To provide these advanced features, SystemFlow requires specific system permissions:

1. ACCESSIBILITY SERVICE API:

SystemFlow utilizes the Accessibility Services API (via SystemFlowAccessibilityService) strictly to register touch and swipe gestures over the camera ring and screen edges to execute navigation actions (Back, Home, and Notification panel shortcuts) on the user's behalf.

* Privacy Guarantee: The Accessibility Service operates entirely offline and locally. It does not monitor, collect, record, or transmit any typed keystrokes, screen content, or personal credentials.

2. OVERLAY DRAWING (SYSTEM_ALERT_WINDOW):

Used to draw the indicator rings around physical camera cutouts and render the local password unlock overlay windows.

3. USAGE ACCESS (PACKAGE_USAGE_STATS):

Required to identify when locked applications are opened in the foreground, allowing the PIN overlay to launch immediately.
