Cookie policy

Last updated: 2026-09-07

A cookie is a small file stored on your device when you visit. Some are essential for the site to work; the rest are only placed with your prior agreement.

What we use today

As of today this site places no consent-based trackers. Our audience measurement (Vercel Web Analytics) is aggregate, sets no cookie and uses no persistent identifier, which places it within the CNIL exemption for audience measurement. That is why no banner is shown.

Tracker categories

Strictly necessary cookies — authentication session (Supabase), language preference, and storing your cookie choices. These need no consent because the site cannot work without them.
Audience measurement — understanding which pages are visited so we can improve the site. Our current tool is anonymous and cookieless.
Advertising and social media — measuring how our campaigns perform. Only placed after your explicit consent.

Your choice, and how to change it

Refusing must be as easy as accepting: the panel offers both options at the same level, in a single click. Your choice is kept for 6 months, in line with CNIL guidance, after which we ask again.

You can also configure your browser to block or delete cookies. Note that blocking strictly necessary cookies may stop parts of the site from working.
