1. What is a cookie ?

A “cookie” is a sequence of information, generally small in size and identified by a name, which can be transmitted to your browser by a website on which you connect. Your web browser will keep it for a certain period of time, and send it back to the web server each time you reconnect to it. Cookies have multiple uses: they can be used to memorize your customer identifier with a merchant site, the current content of your shopping cart, an identifier allowing you to trace your navigation for statistical or advertising purposes, etc. Apart from cookies, there are other similar tracking technologies, such as tags, pixels or local storage. For convenience, the term "cookies'' covers all tracking technologies.

4. Right of opposition (Opt-out) to the use of the audience measurement and analysis solution (Piano Analytics)

Our website uses Piano Analytics audience measurement cookies to measure the audience for our services and content (statistics may be, for example: the number of visits, pages viewed, time spent on the site, connection region, type of device and browser used, etc.).

In accordance with article 82 of the Data Protection Act, supplemented by CNIL deliberation n°2020-091 of September 17, 2020, these trackers may, under certain conditions, fall into the category of trackers strictly necessary for the operation of our services and benefit from a waiver of consent.

By consenting to the deposit and reading of Piano Analytics audience measurement cookies, you allow us to measure the audience for the content present on the website and to improve its operation based on your browsing and profile data.

By not consenting to the deposit of Piano Analytics audience measurement cookies, our less precise audience measurement is limited to the criteria defined by the CNIL to be strictly necessary for the proper functioning of our services and therefore exempt from consent; thus, the data used only allows the production of anonymous visit statistics.

However, you can refuse all tracking by activating the option below. Please note that by clicking on the following button, we will no longer be able to optimally measure and improve our sites.

I refuse any follow-up via the Piano Analytics solution
