Privacy Policy
Last updated: June 11, 2026
What we collect
When you create a MathMentor account we collect your email address and the display name you choose. For each student profile you add, we store the name, course selection, and optional interests you provide, plus the practice answers submitted so we can track progress and adapt question difficulty.
Payments
Payments are processed by Stripe. We never see or store your card number. We keep only a reference to your Stripe customer record and your subscription status.
How we use your data
Your data is used solely to run the service: signing you in, tracking student progress, selecting the next practice question, and managing your subscription. We do not sell your data or share it with advertisers.
Children's information
Student profiles are created and managed entirely by the parent account holder. Student profiles do not have their own logins, email addresses, or contact information — only a first name (or nickname), a course, and practice history.
Where your data lives
Account and practice data is stored with Supabase (Postgres) and the application runs on Google Cloud. Access is protected by row-level security so each parent can only read their own family's data.
Deleting your data
Email kevinfjoy@gmail.com from your account email and we will delete your account, student profiles, and practice history.
