Privacy & legal notice

The end-of-session quizzes of the course taught at the Université Catholique de Lille (sitraka.lu/teaching/data-analytics/) require signing in with a Google account; Google handles that sign-in under its own privacy policy. Signing in creates an account on this site with your name, e-mail address and profile picture as Google sends them. For each quiz we keep your answers, your score and the start and end times. Purpose: the course participation grade, and nothing else; only that grade, as part of your course mark, goes to the university. Only the instructor can see your answers and scores; Supabase hosts them in the European Union as a processor. While you take a quiz, your answers in progress are also kept in your browser, so that a reload does not lose them. Everything is deleted by 31 March 2027 at the latest, once grades are final, including the sign-in account if you use no other feature of the site. Without a Google account, or if you prefer not to use one, you take the same quiz on paper, with the same weight. The controller and the legal basis are being confirmed with the university's data protection officer. To access your data or have it deleted sooner: sitrakaforler@gmail.com. Openings of the course decks are also counted, per day and per deck, with a plain counter: no account, no IP address, no cookie.

On the course slides (sitraka.lu/teaching/) you can write a note under each slide. Without an account, these notes stay in your browser's storage and are sent nowhere. If you choose to sign in with a Google account, they are also saved on that account so you can find them on your other devices: we then keep your name, e-mail address and profile picture as Google sends them, and for each note the course, the slide number, the text and the time of the last change. Only you can read them; the instructor cannot. Supabase hosts them in the European Union as a processor. Legal basis: your consent, given by signing in, which you can withdraw at any time by deleting your notes from the slides and signing out. Notes are deleted by 31 March following the end of the course at the latest, together with the sign-in account if you use no other feature of the site. The session code is still required to open the slides, with or without an account. To access your data or have it deleted sooner: sitrakaforler@gmail.com.

The public slides of the lecture "EU strategy for data, in production" (sitraka.lu/teaching/eu-data-strategy/) can be read freely. To download the PDF, you sign in with a Google account and answer a short questionnaire: your background (student, lawyer, engineer, manager, public sector, other), a usefulness score from 1 to 5, and optionally the most useful part, what to improve, and whether you agree to be contacted. We keep these answers, the language of the deck, the time, your account identifier and, only if you agree to be contacted, your e-mail address. Purpose: improving the lecture and, with your agreement, contacting you about it. Only the lecturer reads the answers; Supabase hosts them in the European Union as a processor. Legal basis: your consent, which you can withdraw at any time. Answers are deleted by 31 October 2027 at the latest. To access, correct or have them deleted sooner: sitrakaforler@gmail.com.

The groups and subjects questionnaire (sitraka.lu/teaching/machine-learning/groupes/) asks for your first name, last name, the group you would like to form, a score from 1 to 3 per subject, and optionally your e-mail address and a comment. It is sent with the code of the introduction session, without an account. Purpose: forming the project teams of three and choosing the examples of the course. Only the instructor reads the answers; Supabase hosts them in the European Union as a processor. Nothing is passed to the school beyond the team composition. Answers are deleted by 31 March 2027 at the latest. To access, correct or have them deleted sooner: sitrakaforler@gmail.com.
