Modilix ("we", "us") provides online course practice, lessons, and tools for students and educators. This policy explains what information we collect, why, and what choices you have. It applies to the Modilix website and app.

Information we collect

• Account info: email address and password (handled by our authentication provider, Supabase — we never see your raw password), or your Google account info (name, email, profile photo) if you sign in with Google.
• Profile & school info: your role (student/educator), display name, avatar, and school/class association if you join or create a school.
• Learning activity: course progress, quiz/test answers and scores, XP, streaks, notes, and discussion posts you create.
• AI tutor conversations: messages you send to the in-lesson AI tutor are sent to our AI provider (Google Gemini) to generate a response, and a usage count is stored so we can enforce fair-use limits.
• Payment info: if you subscribe to Premium, payment is processed by Stripe. We do not store your card details — Stripe shares with us only what's needed to manage your subscription (plan, status, billing dates).
• Device & technical data: a randomly generated device identifier stored in your browser, and your IP address at signup, used only to prevent spam accounts and abuse of free trials — not to track you across the web.

How we use it

• To provide the service: save your progress, show your courses, run the AI tutor, and process subscriptions.
• To keep the platform trustworthy: detect and limit spam signups, fraudulent free-trial claims, and abusive posting.
• To communicate with you about your account, such as billing or security notices.
• We do not sell your personal information, and we do not use your learning data for advertising.

Students & minors

Modilix is built for high school students, many of whom are minors. Educators create or manage school/class associations, and we collect only the information needed to run the course (progress, scores, and account basics) — not more than a typical school platform would need. Parents or guardians with questions about a student's data can contact us using the details below.

Data sharing

We share data only with the service providers that help us run Modilix — Supabase (database & authentication), Google/Firebase (sign-in), Google Gemini (AI tutor responses), and Stripe (payments) — each bound by their own privacy and security obligations. We don't share your data with advertisers or data brokers.

Your choices

• You can review and update your profile info from Settings at any time.
• You can delete your account from Settings, which removes your profile and associated learning data.
• You can ask us to access, correct, or delete your personal data by contacting us.

Data retention & security

We keep your data for as long as your account is active, or as needed to provide the service and meet legal obligations. Data is stored with our infrastructure provider (Supabase) using encryption in transit and access controls limiting who can see it.

Changes to this policy

If we make material changes, we'll update the date at the top of this page and, where appropriate, notify you in the app.
