ACCESSIBILITYSERVICE API USAGE DISCLOSURE

--------------------------------------------------

Volume Lock uses the AccessibilityService API strictly to provide parental control and settings

protection features:

1. What is it used for?:

The Accessibility Service is used solely to detect when protected app screens (such as system

settings or camera) are opened while the lock service is running. This allows the app to redirect

to the security PIN screen to prevent unauthorized tampering or uninstallation of volume controls.

2. Privacy and Data Collection:

• The AccessibilityService API is NOT used to collect, store, or share any personal, private,

or sensitive user data.

• It DOES NOT read, record, or track screen content, keystrokes, voice calls, or personal

files.

• The service runs with minimal scoped permissions (canRetrieveWindowContent = false).
