Use of cookies

The user is informed that the site may use cookies, tracers and/or connection tokens. These may be installed on your device subject to the choices and options you have expressed or may express at any time in accordance with this cookie use and management policy.

Why this cookie use and management policy?

In the interests of information and transparency, this cookie policy is intended to allow the user to find out more about the origin and purpose of the browsing information processed when visiting the sites, and about their rights.

What are cookies?

Cookies are data used by a server to send state information to a user's browser, and by that browser to send state information back to the originating server. State information may be, for example, a session identifier, a language, an expiry date, a response domain, etc. Cookies make it possible to retain state information, for the period of validity of the cookie concerned, when a browser accesses the various pages of a website or when that browser later returns to that website. Only the issuer of a cookie can read or modify the information it contains. There are different types of cookies: - session cookies, which disappear as soon as you leave the site concerned; - persistent cookies, which remain on your device until they expire, or until you withdraw your consent to these cookies being placed on our website, or until you delete them using your browser's features.

Why do we use cookies?

Some of these cookies are used solely to enable or facilitate electronic communication. Others are strictly necessary to provide an online communication service at your express request. Others still are used to improve browsing by analysing how users navigate. The main purposes of the cookies used are: - to enable the website to function properly - to count visitors and identify how they use the sites; - to count and distinguish visits; - to adapt the display to your preferences and to the characteristics of your device; - to identify the site or search engine from which you arrived on our sites; - to manage and track your cookie choices; - to manage user sessions and your browser's features; - to produce statistics and analyses of traffic, use and navigation, and audience measurements of the sites and their various sections, in particular with a view to improving them.

Information about the website

The publisher informs you that you may withdraw your consent to all or some of our cookies at any time. To do so, simply refuse the use of all cookies (except cookies necessary for the proper functioning of the site) or select only the cookies you wish to keep. During your visit, the publisher also informs you that you can refuse the placing of cookies by configuring your web browser. Several means of doing so are set out below. The user can configure their browser to accept or refuse cookies on a case-by-case basis before they are installed. In addition, the user can also regularly delete cookies from their device via their browser. Cookie management and user choices are configured differently in each browser. This is described in the help menu of the browser used, which explains how to change your cookie preferences. For example:


- for Internet Explorer™: http://windows.microsoft.com/fr-FR/windowsvista/Block-or-allow-cookies ;

- for Safari™: http://www.apple.com/legal/privacy/fr-ww/cookies/;

- for Chrome™: http://support.google.com/chrome/bin/answer.py?hl=fr&hlrm=en&answer=95 647

- for Firefox™: https://www.firefox.com/fr/privacy/websites/cookie-settings/

- for Opera™: http://help.opera.com/Windows/10.20/fr/cookies.html

In any event, the user can consult their browser's help section to find out how their browser allows them to choose which cookies are accepted or refused. It follows from the above that the storage of a cookie on your device essentially depends on your wishes, which you can express and change at any time, free of charge, through the choices offered by your browser software. If your browser is configured to accept cookies on your device, cookies embedded in the pages and content you have viewed may be stored temporarily in a dedicated area of your device. They can be read there only by their issuer. Conversely, you can configure your browser to refuse cookies. In this respect, please note that if you configure your browser to refuse cookies, certain features, pages or sections of the sites may not be accessible, for which the publisher cannot be held liable. We also draw the user's attention to the fact that, when the user objects to the installation or use of a cookie, a refusal cookie may be installed on their terminal equipment. If this refusal cookie is deleted, it will no longer be possible to identify the user as having refused the use of cookies. Remember to configure all the browsers on your various devices (tablets, smartphones, computers, etc.).
