3. Frequently Asked Questions

3.1. What are cookies?

Cookies are small files containing information that may in particular relate to a website's visitor, his or her visit and the context of his or her visit, which the server hosting the visited site deposits on the device used by the visitor at the time of the visit so that they can be used from that moment and for as long as they are kept.
When the site visited uses services operated by third-party sites or establishes partnerships with third-party sites, the latter are also likely to deposit and use cookies.
Cookies may constitute personal data, the processing of which is subject to the applicable legislation.

3.2. What are cookies used for?

Cookies are used to make it possible to visit and use a website and, beyond that, to achieve the purposes defined by the owner of the visited site or the owners of third-party sites operating services on the visited site or with which the visited site has established a partnership.
The purpose of cookies and the fact that they come from the site visited or from a third-party site allow them to be categorised:

  • Necessary versus optional cookies
  • First-party cookies versus third-party cookies

3.3. Is it mandatory to accept cookies?

In absolute terms, it is never mandatory to accept cookies. Visitors to a site can configure their browsers to refuse all cookies.
In practice, refusing all cookies often prevents users from visiting a website or using all its features. This is also true for this site.
When a website requires the acceptance of cookies, the best practice (i.e. the only one that complies with the legislation in force), consists of clearly and comprehensively informing visitors and activating by default only those cookies that are strictly necessary for visiting the site. Through the use of its basic features, the website shall also allow visitors, if they wish and without any obligation, to activate other cookies or categories of cookies.

3.4. How long are cookies stored?

The storage period for cookies is stipulated in their definition. It may correspond to the period of the visit to the site or continue beyond this according to the limit defined by the cookie’s designer.
It also allows cookies to be categorised:

  • Session cookies versus persistent cookies
