ScreenWin

How it works
- Children earn screen time by correctly answering multiple-choice questions (MCQs) tailored to their grade level, from first grade (CP) to twelfth grade (Terminale).

- When the allotted time is up, monitored apps (games, videos, social media) are automatically blocked.

- Parents can adjust the time earned (from 1 to 5 minutes per correct answer).

Series bonuses, progressive penalties, and reward rounds make it a fun and balanced experience.

Use of the Android Accessibility Service
ScreenWin uses the Android Accessibility Service solely to detect which application is open in the foreground, in order to display the blocking screen when the allowed screen time is exceeded.

- No screen content, keystrokes, passwords, or personal information are read, recorded, or transmitted.

- The service only reads the package name of the active application (e.g., "com.roblox.client").

- All information remains on the device and is never sent to a server or shared with any third party.

- The user can disable the service at any time from the Android settings (Settings > Accessibility > ScreenWin), and the application will continue to function partially, without the application blocking feature. - This feature is essential to the core of the product (parental screen time control), which is why we use the Accessibility API, the only Android API that reliably detects which application is open on recent versions of Android.
