Cookies policy

This website does not use cookies: no first-party or third-party cookies, no analytics and no advertising. It does not load fonts, maps or videos from external services that could set them, which is why we do not ask for consent.

The only exception: the Datadis authorisation pages, reachable only through a personal link, use a technical session cookie that is strictly necessary for the form to work and is deleted when you close your browser.

Should we ever add a non-essential cookie, we will update this policy and ask for your consent first.
