Privacy

Who is responsible

Tobos FlexCo, as named in the imprint. Questions about your data: hey@tobos.ai.

What we process, and why

We process only what we need to run this site. There are no accounts, cookies, analytics or tracking, and nothing is loaded from other companies.

Visiting a page. To send you a page, our server has to process your IP address and the address you request. Its error logs, which can contain your IP address, are deleted after 7 days.

Answering a question in a chapter. Your answer and how sure you were are saved in your browser, so the question stays answered when you come back. They are not sent to us or anyone else.

Writing an exercise. Your answers are saved in your browser, where we can't see them. To seal your file, the editor sends your text and your edits to our server, which checks them and signs the result; it stores none of it. To limit requests, it keeps your IP address in memory for one minute. The file you download holds your answers, the reminders the editor showed you, and the seal. If you hand it in on TUWEL, TU Wien processes it under its own privacy policy.

The legal basis is our legitimate interest in running this site and its exercise editor securely and without abuse (Art. 6(1)(f) GDPR).

Hosting

Hetzner Online GmbH, Germany, hosts the site for us on a server in Helsinki, Finland. Your data stays in the EU.

Your rights

You can ask for access to your data, its correction or deletion, a restriction of its processing, or a copy of it, and you can object to its processing (Art. 15–21 GDPR): write to hey@tobos.ai. You can also complain to the Austrian Data Protection Authority (Datenschutzbehörde, dsb.gv.at).
