Duden Learnattack: sovereignty score and 8 European alternatives

Duden Learnattack is an online learning platform for school students from grade 4 up to the Abitur. It offers video explanations, step-by-step guides, practice exercises with immediate feedback and classroom tests with model solutions, covering subjects such as mathematics, German, English, French, biology, chemistry and physics. It also offers an AI tutor, Kim, which subscribers can reach via WhatsApp. The service runs in the browser on any device and is sold as paid memberships.

The service is offered by Duden Learnattack GmbH, which has its registered seat in Berlin and is entered in the Berlin commercial register. The website does not describe ownership, and a supply-chain notice refers to the Cornelsen group without stating whether it holds a stake. Hosting locations are not named, and the pages consulted contain no GDPR or DSGVO statement, only a general reference to security and privacy. As a German provider it is subject to EU data protection law, but a European organisation should request the hosting location and a data processing agreement before use, particularly for pupils' data.
