When you visit this website, information may be recorded in “cookie” files stored in the browser of your terminal (computer, tablet or cell phone). This page explains what a cookie is, what it is used for and how you can accept or reject those that are not essential to the operation and management of the site.
— What is a cookie?
A cookie is a small text file containing small amounts of information (notably an identifier in the form of a number, (a session for example), a choice of language, a code designed to protect your browsing, the name of the server that deposited it and possibly an expiry date) and likely to be temporarily recorded, subject to your choices for cookies not necessary for the operation of the site, on the hard disk of your terminal when you consult a web site using your browser software. Cookies are managed by your web browser, and users can read them by right-clicking on the web page and “Inspect code”.
A cookie can be either a session cookie or a permanent (or persistent) cookie.
A session cookie persists only during the browsing session, and is deleted when the browser is closed. A permanent cookie is set for a specific period of time. This type of cookie remains on the terminal until it expires, or until it is deleted from the computer via the browser settings or extensions.
The cookie does not identify you personally, but only your terminal’s browser. Some cookies require your prior consent before being installed on your terminal.

How do I manage cookies?
Cookies whose sole purpose is not to enable or facilitate communication by electronic means or which are not strictly necessary for the provision of an online communication service at the express request of the user require the prior consent of the Internet user.
Tracers whose purpose is limited to measuring the anonymous audience of the site or application, in order to meet various needs necessary for the operation and day-to-day administration of a website are not subject to consent.
There are several complementary ways of managing cookies :
- Accept or refuse unnecessary or non-functional cookies using the Axeptio certified consent tool. A “Cookie management” widget button allows you to accept or refuse cookies requiring consent, in particular those from third-party companies. The widget provides information on the purposes of these cookies and a link to their privacy protection policy via a “?”.
- Exercise your choices with third-party companies by consulting their privacy protection policy. You will find there the purposes of use, in particular advertising, the browsing information that they may collect thanks to the application buttons available on the site consulted, and you will be able to configure your user accounts to accept or refuse the tracers deposited by these companies.
- Control cookies using your browser settings. Most of these tracers can be deactivated by setting your browser so that it only accepts tracers from the sites visited (refuse “third-party sites”, tick the Do not track me box on most browsers) in the preferences of your browser software. In “Private Browsing” mode, cookies will only disappear when you close your browser window.
