Cookies and their use


What’s a cookie?

  • A cookie is a small text file that is placed on your device (e.g. a computer, tablet, smartphone, connected TV, games consoles with an online connection) when you visit a website or view an ad.
  • It contains several items of data: the name of the server that sent it, a unique ID number and sometimes an expiry date. Cookies have different purposes. They save your language settings on a website, collect information on your browsing history and send you customised services.
  • Only the sender of a cookie can read, save or edit the information inside it.


Our cookies

Our website uses different types of cookie. Their roles are described below, subject to your choice (refer to the chapter: Accepting or declining cookies).

They let you:

  • use the main website functions and ensure the security of your connection (for example, access to your account);
  • access the reserved, personal areas of our website, such as your account, using identifiers or data that you may have provided previously;
  • implement security measures, for example, when you are asked to reconnect to specific content or services after a certain period of time.

Functional / functionality cookies

These cookies are not essential for browsing our website but let you optimise operation by giving you access to specific functions. They enable us to:

  • adapt website presentation to the display preferences of your device (language used, display resolution, operating system, etc.) when you visit our website.

Analytical / audience measurement cookies

These cookies provide us with information on the performance and use of our website. They let us compile statistics, traffic and data on the use of the various components of our website (pages and content visited, click streams). This enables us to improve the relevance and ergonomics of our services (for example, the pages most frequently viewed or looked for via our search engine, etc.).

We use Google Analytics tags for these various surveys.
