Almost all websites use cookies. A cookie is a small file that saves Internet settings and is downloaded from the browser when first accessing the website. The next time the user returns to the site using the same device, the browser checks for the presence of a related cookie (i.e. containing the name of the site) and uses the data within the cookie to be sent back to the site. This allows sites to recognize the browser and, in some circumstances, to vary the content shown depending on the case.

Some cookies are very useful to facilitate navigation when a user visits a website previously consulted. If you use the same device and the same browser, cookies can for example remember your preferences, and make the content displayed more relevant to your interests and needs.

There are 4 main types of cookies generally used on websites:

Strictly necessary cookies: these cookies are essential in order to allow you to browse a website and use its features, such as accessing secure areas of the website. Without these cookies, some services (such as selecting a product to buy it) could not be provided.

Functional cookies: these cookies allow a website to remember the choices you have made previously (such as user name, preferred language or geographical area in which you are) and to provide advanced or personalized features. For example, they can be used to remember information about your account and personal preferences, or to provide the services you have requested such as evaluating an opinion or sharing content via social media. The information collected by these cookies can be made anonymous, preventing the tracking of your activity on the web.

Performance cookies: these cookies collect information on how users use a website, for example which pages they view most often and whether they display error messages. These cookies do not collect information that allows you to identify users. All information collected by these cookies is aggregated and users therefore remain anonymous. The information is used only to improve the functioning of a website.

Cookies for targeted advertising: these cookies are used to display advertising messages that are more relevant and more in line with your interests. They are also used to limit the number of times an ad is viewed and help measure the effectiveness of an advertising campaign. These cookies remind you that you have visited a website and this information is shared with other companies such as publishers and advertisers.
