A cookie is a small file of letters and numbers downloaded on to your computer when you access certain websites. Like virtual door keys, cookies unlock a computer’s memory and allow a website to recognise users when they return to a site by opening doors to different content or services. Like a key, a cookie itself does not contain information, but when it is read by a browser it can help a website improve the service delivered.
Cookie files are automatically lodged into the cookie file – the memory of your browser – and each one typically contains:
A value – usually a randomly generated unique number
The website server which sent the cookie uses this number to recognise you when you return to a site or browse from page to page. Only the server that sent a cookie can read, and therefore use, that cookie.
Who is likely to place cookies on your device, and for what purpose?

Third parties: service providers, partners, advertisers, advertising sales houses
Third parties are likely to place cookies on your device.

Indeed, the mere fact that your account with a social network is activated on your device (open session) when you browse the Site, can allow that network to monitor your navigation of the Site.
Cookies are likely to be placed on your device through advertising spaces on the Site.
These cookies may be set at the level of the advertising content displayed in our advertising spaces either by the advertisers themselves, or by their ad serving providers (third party ad servers) such as communications consultancies, audience measuring firms and targeted advertising providers: the cookies are associated with the advertising content.

– to compile statistics;
– to collect navigation data on devices browsing the Site and, for instance, limit the number of times an advertisement is displayed and/or enable advertisements to appear in a precise order;
– to recognise your device if and when you subsequently browse any third party website or service on which these advertisers third party ad servers also issue cookies and, if applicable, adapt these third party websites and services, or the advertisements they show, to any navigation data from your device that may be known to them; and
– to determine whether a particular advertising campaign has produced the desired results by keeping track of how many people clicked on the advertising content or visited the advertiser’s website after seeing the advertisement on the Site.
Cookies may also be placed in our advertising spaces by the company in charge of managing our advertising spaces: the advertising sales house. These cookies enable the advertising sales house:
– to do the counting necessary to calculate the amounts to be paid to the various advertising stakeholders and to compile statistics;

– to customise the advertising content displayed on your device through our advertising spaces to your browsing patterns and geographic location;
– to customise the advertising content displayed on your device through our advertising spaces to your browsing patterns on third party websites.
