What is a cookie or other trackers?

You are informed that, when browsing our websites, cookies can be placed on your web browser to enable, in particular, optimal browsing. Cookies are data stored on your terminal equipment. Our websites use cookies to send information to your browser, enabling the browser to pass data back to the original website (for instance, a session ID, language preference or a date). Other types of trackers, such as Web beacons, can also be used. These beacons make calls to servers to display a pixel and enable us to share data with third parties for the purposes described below.

Cookies and other trackers do not allow, under any circumstances, any automatic access to any other file on your computer. No unauthorised third party can access the data stored in the cookie. We may, however, use technologies supplied by third parties that result in the placement and use of trackers for purposes of their own.

Some third-party services may use invisible pixels when sending external newsletters to subscribers. Loading invisible pixels enables them to measure certain behaviours such as the opening of the email or clicking on a link for audience measurement purposes.

When loading a share button bar on our websites, some third-party services may collect non-personal data, using cookies and invisible pixels. They may thus use information about your visits to our websites to offer you ads on other websites about goods and services of possible interest to you.

What choices do you have in terms of cookie management?


You have the choice of setting your browser to accept all cookies, block all cookies, or to inform you whenever a cookie is created, its period of validity and its content, and to refuse the registration of the cookie on your terminal, or else to delete cookies periodically. You can configure your Internet browser settings to disable cookies. However, bear in mind that if you block all cookies you may not be able to use some of the features of the website.

JCDecaux draws your attention to the fact that if you decline the placement or use of a cookie, a refusal cookie will be installed on your terminal equipment. If you delete this refusal cookie, it will not be possible to identify you as having refused the use of cookies. Similarly, when you consent to the use of cookies, a consent cookie is installed. Consent or refusal cookies must stay on your terminal equipment. These types of cookies expire after 13 months.
