This policy explains what personal data we process and why. Your privacy matters to us.

1. Data we process

When you sign in with Google or GitHub we process your name, email address and profile picture. We also store training data — sessions, attempts, submitted queries and results.

We automatically process technical data (e.g. browser type) and data from analytics and advertising cookies, if you have consented.

2. Purpose and legal basis

We process data to provide the service (performance of a contract), to track your progress and to improve the platform. Analytics and advertising cookies are processed only based on your consent.

3. Recipients and processors

We use the following providers: Google and GitHub (sign-in), Neon (database), Vercel (hosting), Google Analytics and Google AdSense (analytics and ads, with consent only).

4. Your rights

You have the right to access, rectify, erase, restrict, port and object to the processing of your data. You can delete your account and related data at any time in settings or by contacting the operator.

5. Retention

We retain data while your account is active. After account deletion, related data is removed unless we are required to retain it for legal reasons.
