Sentiam is run by the founding team as natural persons. There is no company behind this site.
An account is optional. Without one, your progress stays on this device.
With an account we store your email, campaign progress (including the courses you added), cluster progress, and an attempt log (exercise, locus, right or wrong, help, time). That is the service the account provides.
You can optionally send a note through Feedback in the header. We store that text and the chosen kind (general, bug, or feature), not joined to your account. An address appears there only if you type it into the box.
We do not use a student-facing AI model, a newsletter, or identifiable usage analytics. We store anonymous visit counts (event, course, page, day, no account) so we can see which parts are used.
The database is in the EU or in Switzerland. In this deployment the host is Supabase (Frankfurt region) as a processor.
You can reset progress, export the data as JSON, or delete the account. Questions: jweide@student.ethz.ch
