Third-party cookies are those that are installed by a site or a web server other than that of this site, but used on the site itself. This site uses third-party cookies, the use of which is subject to the user’s consent.

Technical cookies are essential for the proper functioning of the sites and can be session (temporary) or persistent (with a duration defined according to the needs of use of the site). The duration of session cookies is strictly limited to the browsing period of the site (once the browser is closed these cookies are deleted). Persistent cookies, on the other hand, have a longer duration than session cookies (with expiration of up to 30 days) and are used to recognize, for this limited period, the user’s computer. Their deactivation compromises the study of how visitors interact with the site. The public part of the website remains however usable.
