### Privacy & Safety
At SafeTouch, your privacy is our top priority. Our app is designed to work entirely locally on your device:
* **No Data Collection**: We do not collect, store, or transmit any of your personal data, screen content, or touch inputs to external servers.
* **Local Processing**: The Accessibility Service (used for ad skipping) and the Overlay Service (used for screen blocking) process all events locally and are never recorded or shared.
* **Permissions**: We only request permissions absolutely necessary for the app to function (Overlay, Accessibility) and do not misuse them.
