When you create an account, we collect your email address and chosen username. When you play games, we store your scores. That's it — no location, no browsing history, no cookies beyond what Firebase requires.
Your full name, grade/class, and school are entirely optional. If you provide them, they are stored in your profile and are only visible to you — we (the site owner/operator) cannot see that information.
Your email is used for login and password resets. Your username and scores are shown on the leaderboard. We do not sell, share, or rent your data to anyone.
All data is stored securely in Firebase (Google Cloud), which follows industry-standard security practices. Firebase's privacy policy applies to the underlying infrastructure.
MATHSIMIZED welcomes learners of all ages. If a parent or guardian wants their child's data deleted, contact us and we will remove it promptly.
You can request deletion of your account and all associated data at any time by emailing mathsimized@gmail.com.
