Cookie management
When you visit a website published by a CNRS entity, information may be recorded in “cookie” files placed in the browser of your terminal (computer, tablet or mobile 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 are cookies?
A cookie is a small text file containing small amounts of information (in particular an identifier in the form of a number, (a session for example, a choice of language, a code to protect your browsing, the name of the server that deposited it and possibly an expiry date) and likely to be stored temporarily, 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 website 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 using the browser settings or extensions.
The cookie does not identify you personally, only your terminal’s browser. Some cookies require your prior consent before being installed on your terminal.

Third party cookies :
Some sites are likely to include computer applications from third parties who may deposit “social” and advertising cookies, targeting and tracking cookies.
In particular the following services:
- Consent or refusal to deposit cookies using the Axeptio tool, published by the French company Agilitation, which has been selected by the CNRS to manage cookies.
- Viewing content via hosts such as YouTube, Dailymotion, etc. for videos.
- For sharing information on social networks, which allow you to share content on the site with other people or to let these other people know about your consultation or your opinion regarding content on our site.
The cookies placed by these third parties may remember the pages and websites you have visited and may collect personal data such as your IP address and share it with third parties. These cookies enable advertising agencies to present you with targeted and personalised advertising. They have a variable lifespan, ranging from session time or a few dozen minutes to several years.
The CNRS site you are visiting has no control over the process used by content hosts and social networks to collect information relating to your browsing, and associated with the personal data they hold.
You can manage the placement of these cookies. To view certain content offered by the CNRS, you must first accept cookies from these third parties.
How do I manage the cookies placed on this CNRS site?
Cookies whose sole purpose is not to enable or facilitate electronic communication 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.
To manage the cookies deposited by a CNRS site, you have several complementary options:
- Accept or refuse non-necessary or non-functional cookies with the Axeptio certified consent tool, which is offered or is being installed on most CNRS sites. On the sites concerned, 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 the purposes for which they are used, in particular advertising, and the browsing information they may collect using the application buttons available on the site consulted, and you can therefore configure your user accounts to accept or refuse the cookies placed by these companies.
- Control cookies using your browser settings. Most of these cookies can be deactivated by setting your browser so that it only accepts cookies from the sites you visit (refuse “third-party sites”, tick the Do not track me box on most browsers) in your browser preferences. In “Private Browsing” mode, cookies will only disappear when you close your browser window.
How do I configure my browsers?
To manage cookies as closely as possible to your wishes, we invite you to configure your browser according to the purpose of the cookies:
- The browser can be set to warn you before a cookie is installed.
- The browser can also be set to refuse all types of cookies or only third-party cookies.
- Any cookies already installed on the computer can be deleted.
- Each browser must be set up separately to refuse cookies.
