2. What data we process

When you register we process your email address and the account and progress data required to use the learning platform. When you visit the site, technically necessary data (e.g. IP address, browser type) is processed.

3. Cookies and consent

Necessary cookies are required to operate the platform (e.g. sign-in). Optional cookies for analytics are only set after consent. You can withdraw your consent at any time with effect for the future by deleting the cookies in your browser.

4. Third-party services

We use Yandex (Metrica and advertising) and Google Analytics (Firebase) for reach measurement and advertising. On the German version only analytics is used, and only after your consent — no advertising cookies are set there.

5. Your rights

You have the right to access, rectification, erasure, restriction of processing, data portability and to withdraw a given consent. You may also lodge a complaint with a data protection authority. Please contact feedback@sql-academy.org.
