This site saves only two preferences in your browser, and only when you choose them. No audience-measurement tools, no advertising, no third-party services loaded (fonts, videos, maps). No other cookies.
The langue cookie
- When: only if you click “Français”, “English” or “Español” in the language selector. Never on a simple visit.
- Content: the language you chose,
fr,enores. Nothing else. - Duration: 12 months at most (some browsers delete it sooner).
- Purpose: to take you back to the language you chose when you return to the home page.
- Who uses it: our server, on the home page only, to send you to the right version. It is not passed on to any third party.
The “kendu-mouvement-pause” preference
- When: only if you click the button that pauses motion (or restarts it).
- Content:
1(motion paused) or0(motion on). Nothing else. - Duration: until you delete it (some browsers delete it sooner).
- Storage: in your browser’s local storage. This value is never sent to our server.
- Purpose: to remember your choice of a display without animation, from one page to the next.
Deleting them
You can delete these two preferences at any time in your browser settings (the section for cookies and site data). The site works the same way without them: the home page then opens in English if your browser is set first to English, in Spanish if it is set to Spanish, Catalan, Basque or Galician, otherwise in French; other pages open in the language of their address; and motion resumes, unless your device asks to reduce animations.
For the rest of your data, see the privacy policy.
