We collect the information you provide when you register (such as your name and email address), and the learning data generated as you use the platform: lesson views, exercise attempts, review ratings, notes, bookmarks, study plans, and streaks.
Your data is used to run the service: to schedule spaced-repetition reviews, show your progress, and personalize what you see next. We do not sell your personal data.
Learning data is stored in our database and associated with your account. Session tokens are stored in your browser's local storage so you stay signed in.
We use browser local storage to keep you signed in and to remember your display preferences. We do not use third-party advertising trackers.
We do not share your personal data with third parties except as required to operate the service or comply with the law. Aggregate, non-identifying statistics may be used to improve the courses.
You can export your data, deactivate your account, or permanently delete your account from the Settings page. Deleting your account removes your personal data from our systems, subject to routine backups.
We use standard measures to protect your data. No system is perfectly secure, so please use a strong, unique password.
The service is not directed at children below the age required to consent to data processing in their jurisdiction.
We may update this policy. Material changes will be reflected by updating the date above.
Privacy questions can be raised through the Help page.
