Privacy Policy & Student Data Protection
Last updated: August 2026
1. Local-First Learning Architecture
Master10 is built on a privacy-respecting, local-first architecture. Your practice sessions, quiz attempts, timer preferences, and mistake diary logs are stored directly on your personal device via local storage. We do not track student browsing habits or sell student data.
2. Google Authentication (Optional)
Students may optionally sign in using Google Firebase Authentication to sync test analytics across multiple devices. We only access standard profile information (email and display name) for identity verification.
3. Zero Intrusive Advertising
Master10 does not display third-party pop-up advertisements or behavioral ad-tracking scripts, ensuring a distraction-free learning environment for minors.
