We do not use any analytics cookies, advertising cookies, embedded social media or any other third-party trackers. Fonts are hosted on our own servers: your browser does not contact any external service to display the website.

Why there is no consent banner
A tracker used solely to store an interface customisation choice made by the user is strictly necessary for the service the user requests. It is exempt from consent under Article 82 of the French Data Protection Act (loi Informatique et Libertés) and the CNIL guidelines (deliberation No. 2020-091 of 17 September 2020). As no other tracker is used, no banner is required.
If we ever add a tool that requires consent (analytics, embedded video, social media, etc.), a banner would let you accept or refuse it just as easily, before anything is stored.
Clear this preference
You can delete this item at any time in your browser settings (under “site data” or “local storage”). The website will then be displayed in the dark version again.
