What is a cookie?
A cookie is a small file stored in your browser; local storage works in a similar way. They let a website remember a choice or measure its traffic, for example.
Necessary (always on)
- your cookie choice, kept in your browser’s local storage for 6 months;
- where your visit came from (source, campaign, utm parameters, fbclid, gclid, landing page), kept in session storage — cleared when the tab is closed — so it can be attached to your request if you fill in a form. It is not sent anywhere else;
- a record of a form submission for 30 minutes in session storage, to prevent duplicates.
Analytics and advertising
No analytics or advertising tool is currently active on this website: no such cookie is set.
How your choice works
Before you choose, no analytics or advertising tool is loaded. You can accept everything, reject what is not necessary, or choose category by category.
You can change your choice at any time with the “Manage cookies” link at the bottom of each page. If you withdraw consent, the tools concerned stop and their cookies are deleted. You can also clear cookies in your browser settings.
