Privacy policy

What we collect

• Account email, display name, exam date, target grade and timezone.
• Practice data: questions served, selected answers, written responses, marks, rubric evidence, mastery, review schedule and topic coverage.
• Subscription status and transaction identifiers. We do not receive your full card details; Apple or Stripe processes payment.
• Basic technical logs needed to operate and secure the service.

Why we use it

• To serve practice, mark answers and calculate mastery and review.
• To provide your account, progress, subscription and support.
• To keep the service secure and diagnose failures.
• To meet legal and accounting obligations.

Who processes it

We use Supabase for authentication, database and storage; Apple for App Store subscriptions; Stripe for web subscriptions where enabled; and a private hosting provider for the backend. These providers process data on our instructions. We do not sell personal data, show advertising, or track you across other apps.

Retention and deletion

Account and practice data are kept while your account is active. You can delete your account in Settings, which removes your profile, attempts, mastery, coverage, subscription entitlement and related data. Billing records may be retained where required by law.

Your choices

You can update your profile in Settings, delete your account, or contact us to request access, correction or deletion. If you believe we have handled your data incorrectly, contact us first so we can resolve it.

Children

StudioA is intended for A-Level students. It is not directed at children under 13, and we do not knowingly collect their data.

Security

Data is transmitted over HTTPS and access is controlled with row-level security. No online service can guarantee absolute security; please use a strong, unique password.

Changes

If this policy changes materially, we will update the effective date and, where appropriate, notify you in the app.
