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.

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 Yandex advertising as well as Mixpanel for reach measurement. On the German version only Yandex.Metrica and Mixpanel are used, and only after your consent — no advertising cookies are set there.

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.
