1. What a cookie is here
A cookie is a small file placed on your device by a site you visit. We also use equivalent technologies, local storage in particular, and this policy covers them under the same name.
2. What we use
Three categories, and only three:
- Strictly necessary : signing you in, keeping your session, protecting forms against cross-site request forgery, and remembering your language. The site does not work without them, and they are not subject to consent.
- Preference : remembering interface choices you have made, such as a filter or a collapsed panel. They never leave your browser.
- Measurement : understanding which pages are consulted, in aggregate. These are set only if you accept them, and refusing them changes nothing about what the site does for you.
3. Session and refresh tokens
Signing in places a refresh token in a cookie that JavaScript cannot read. The short-lived access token that accompanies each request is held in memory only and disappears when you close the tab. That split is deliberate: a script injected into the page cannot read either the refresh cookie or a token stored on disk, because neither exists in a readable form.
4. Changing your choice
You can withdraw or change your consent at any time from the cookie settings link in the footer. You can also delete cookies or block them entirely in your browser settings; blocking the strictly necessary ones will prevent you from signing in.
