What are cookies?

Cookies are text files that are placed and stored on the hard drive of your terminal (computer, Smartphone, tablet or any other device that can be used to browse the internet) by a website server.

Some of these cookies are required to access some site functionalities. Others are used to analyze the web traffic, record statistics and site visit figures (number of visitors to each page, geographical origin of the devices used to visit the site, etc.) and statistics concerning the consultation and use of various elements present on the site (sections and content browsed, duration of visit, etc.). They can also be used to provide additional services such as the sharing of content on a website via social networking sites, improving the website in order to tailor it to visitor needs. A cookie in no way gives us access to the user’s computer or any information about the user other than the data the user expressly agrees to share with us.

You are not obliged to accept the use of cookies and can choose to refuse them by changing your internet browser settings, as explained below.
