What is a cookie?

Cookies (and trackers) or identical technologies are files used to record information about your browsing on our website and mobile application (together, the “Website”). By accessing our Website, cookies may be installed on your browser or device for multiple purposes.

What types of cookies do we use, and how do we use them?

24 Sèvres uses both essential cookies (necessary to have a functional website and provide you with the associated services) and specific cookies (used for specific purposes).

Essential cookies are strictly necessary to provide the services available on our Website. They range from cookies to store your choices (for example, your privacy and language preferences) to cookies for secure website use and access (such as the authentication mechanism).

Essential cookies are intended to facilitate your user experience. Their use is strictly limited to 24 Sèvres.

Specific cookies are used for other purposes, such as allowing 24 Sèvres to understand how the Website is used or enabling you to share information on social networks. These cookies are not required to use our Website but provide additional services that may suit your needs.

The same cookies and technologies allow us to:

  • establish statistics and measure the volume of traffic and the use of the various Website components (such as visited sections and contents and clickstream), enabling 24 Sèvres to improve the utility and ergonomics of its services;
  • adapt the presentation of our Website to your device’s display preferences (language, resolution, operating system, etc.) when you visit the Website according to your device’s hardware and software for viewing or reading;
  • to the extent that you provided us with data, in particular your electronic contact details, when you registered, ordered, or accessed any of our services, link your data with browsing information to send you, for example, marketing emails or display specifically personalised advertisements that may be of interest to you on your device in advertising spaces we issue;
  • to the extent that you provided us with your data (wishlist, shopping preferences, participation in promotional events, etc.), including your electronic contact details, when you registered or accessed 24 Sèvres services, link such data with browsing information relating to your device to send you, for example, 24 Sèvres electronic solicitations materials and provide advertisements based on your interests via our network of selected advertisers;
  • store information about a form you completed on the Website (account registration or access) or products, services, or information you selected on the Website (subscribed service, shopping basket contents, etc.);
  • give you access to reserved, personal areas of the Website, such as your account, using identifiers or data that you may have previously entrusted to us;
  • implement security measures, for example, when you are required to log in again if you have not accessed certain contents or a service after a period of inactivity;
  • combat Internet fraud (preventing payment method fraud, identity theft, etc.). As such, 24 Sèvres or its service providers acting on its behalf may place trackers, subject to your rights, to collect information about the device used to place an order (in particular, the operating system, the location of the machine, whether a proxy is used, etc.). These “fingerprinting” trackers associated with your order data are used to validate your order, payment method, and delivery method.

How do I customise my choice of cookies?

When using our Website for the first time, you will be able to use our consent management interface to select which cookies you will accept.

Essential cookies are accepted by default, while specific cookies are disabled and must be selected by you before they are installed on your browser.

Our consent management interface allows you to accept or refuse all cookies or select specific cookies.

You can change your cookie preferences at any time by clicking the “Cookies” tab at the bottom of our Website.

How long do cookies last?

There are two types of cookies: session and persistent.

Session cookies are temporarily created in your browser’s subfolder when you visit a website. When you leave the site, the session cookie is deleted.

Persistent cookies remain in your browser’s subfolder and are enabled again when you visit the website that created that specific cookie. A persistent cookie remains in the browser’s subfolder for the duration defined in the cookie file.

Generally, a cookie’s maximum validity period is 13 months.

To ensure that you are comfortable with your selection of cookies, we may ask you to renew your consent to certain cookies.
