Cookies can be classified according to how long they are stored:

• Session cookies: These expire when the user closes the browser.
• Persistent cookies: These expire when the purpose for which they were used is fulfilled (for example, to keep the user identified across the services) or when they are manually deleted.

Depending on who owns the cookies, they can be classified as follows:

• First-party cookies: These are sent to the user’s terminal from a device or domain managed by the website owner from which the service requested by the user is provided.
• Third-party cookies: These are sent to the user’s terminal from a device or domain that is not managed by the website owner but by another entity that processes the data obtained through the cookies.

In addition, cookies can be classified according to their purpose:

• Performance cookies: This type of cookie stores the user’s preferences for the tools found on the site so that they do not have to configure the service each time they visit. This type includes volume settings for video or audio players, for example.
  Video streaming speeds compatible with your browser.
• Geo-location cookies: These cookies are used to find out which country you are in when a service is requested. This Cookie is completely anonymous, and is only used to help tailor content to your location.
• Registration cookies: Registration cookies are generated once users have registered, or subsequently logged in, and are used to identify them in the services for the following purposes:
  • To keep the user identified so that, if he closes a service or website, browser, or computer and later tries to access the service or website again, he will still be identified, thus facilitating his browsing, without him having to identify himself again.
  • This feature is nullified if the user selects the “Log out” function, thereby deleting this cookie. The next time the user enters the service he will have to log in to be identified.
  • To verify whether the user is authorised to access certain services; for example, to participate in a contest.

• Analytical cookies: Each time a User visits a service, a tool from an external provider generates an analytic cookie on the user’s computer. This cookie is only generated upon the visit, functioning, in future visits, to help Web Services to anonymously identify the visitor. The main objectives to be achieved are:
  • To allow for the anonymous identification of users through “Cookies” (identifying browsers and devices, not people) and, hence, the approximate calculation of the number of visitors, and these trends over time.
  • To anonymously identify the most visited content and, therefore, that most attractive to users.
  • To determine whether the user accessing is a new or returning visitor.
  • Important: Unless the user decides to sign for a service of the website, the “Cookie” will never be associated with any personal data that can identify him. These Cookies will only be used for statistical purposes to help optimise users’ experience on the site.
• Behaviour-based advertising cookies: These types of “Cookies” make it possible to expand the information of the ads displayed to each anonymous user in the Web Services. Among other things, the duration or frequency of the displaying of advertisements, interaction with them, and browsing patterns and/or user behaviour are stored, among others, as they help to form a profile for advertising purposes. In this way, they make it possible to offer advertising that is tailored to the user’s interests.
• Third-party advertising cookies: In addition to the advertising managed by the Website through its Services, the Website offers its advertisers the option to place advertisements through third parties (“AdServers”). In this way, these third parties can store cookies sent by the web services from the users’ browsers and access the data stored in them.
