🔒 ACCESSIBILITY SERVICE API USAGE & DISCLOSURE

Screen Privacy Guard uses the Android AccessibilityService API solely for its optional "Auto-Enable by App" automation feature.

• Purpose: When you enable the "Auto-Enable by App" feature and select specific applications (such as banking or messaging apps), Screen Privacy Guard uses the AccessibilityService API to detect window state changes (active foreground app package names).
• How It Works: When an app you selected is brought to the foreground, Screen Privacy Guard automatically turns ON your privacy screen overlay. When you switch away or close that app, the privacy overlay is automatically turned OFF.
• Zero Data Collection: The AccessibilityService API is used exclusively to identify active foreground app package names to trigger the overlay. We DO NOT access, read, monitor, collect, store, or transmit any user inputs, keystrokes, passwords, text messages, sensitive screen contents, or personal information.
• User Control & Consent: The Accessibility Service is completely optional, requires your explicit in-app consent before activation, and can be enabled or disabled at any time in the app settings.

🔒 PERMISSIONS USED:
• Display over other apps (SYSTEM_ALERT_WINDOW): Required to display the privacy overlay filter over your screen.
• Accessibility Service (BIND_ACCESSIBILITY_SERVICE): Optional; used solely to automatically activate the filter when user-selected apps are launched.
• Foreground Service: Required to maintain consistent filter overlay protection while using other apps.

Your privacy belongs to you. Keep your sensitive data safe from shoulder surfers with Screen Privacy Guard!
