Accessibility Service Usage

This app uses the Accessibility Service API to enable the App Lock and Focus Mode (Pomodoro) features.

For App Lock, the Accessibility Service helps detect when a selected app is opened so the app can display a lock screen or PIN prompt to protect user privacy.

For Focus Mode (Pomodoro), the Accessibility Service is used to temporarily block selected distracting apps during a focus session, helping users stay productive until the session ends.

The Accessibility Service is used only for these purposes.

We do not collect, store, monitor, or share any personal or sensitive user data.
No data is transmitted outside the device, and all processing happens locally on the user’s device.

Accessibility permission is optional and is required only if the user enables App Lock or Focus Mode features.
