Cookies are files that can be downloaded to your computer through web pages. They are tools that play an essential role in the provision of numerous information society services. Among others, they allow a website to store and retrieve information about the browsing habits of a user or their equipment and, depending on the information obtained, can be used to recognize the user and improve the service offered. Types of cookies Depending on who is the entity that manages the domain from which cookies are sent and treats the data obtained, two types can be distinguished:

• Own cookies: those that are sent to the user’s terminal equipment from a computer or domain managed by the editor itself and from which the service requested by the user is provided.
• Third-party cookies: those that are sent to the user’s terminal equipment from a computer or domain that is not managed by the editor, but by another entity that processes the data obtained through cookies. In the event that the cookies are installed from a computer or domain managed by the editor itself but the information collected through these is managed by a third party, they cannot be considered as own cookies.

There is also a second classification according to the length of time that they remain stored in the client’s browser:

• Session cookies: designed to collect and store data while the user accesses a web page. They are usually used to store information that only needs to be kept for the provision of the service requested by the user on a single occasion (e.g. a list of products purchased).
• Persistent cookies: the data remains stored in the terminal and can be accessed and processed for a period defined by the party responsible for the cookie, which can range from a few minutes to several years. Finally, there is another classification with five types of cookies according to the purpose for which the data obtained are processed:
• Technical Cookies: those that allow the user to navigate through a web page, platform or application and the use of the different options or services that exist in it as, for example, control traffic and data communication, identify the session, access parts of restricted access, remember the elements that make up an order, make the buying process of an order, make the application for registration or participation in an event, use security features while browsing, store content for broadcast video or sound or share content through social networks.
• Personalization cookies: allow the user to access the service with some general characteristics predefined according to a series of criteria in the user’s terminal, such as the language, the type of browser through which the user accesses the service, the regional configuration from where the user accesses the service, etc.
• Analysis cookies: they allow the person responsible for them to monitor and analyze the behavior of the users of the websites to which they are linked. The information collected through this type of cookies is used to measure the activity of the websites, application or platform and for the elaboration of browsing profiles of the users of such sites, applications and platforms, in order to introduce improvements based on the analysis of the data on the use made by the users of the service.
• Advertising cookies: allow the management, in the most effective way possible, of advertising spaces.
• Behavioral advertising cookies: store information on user behavior obtained through the continuous observation of their browsing habits, allowing the development of a specific profile to display advertising based on this.
• Cookies from external social networks: they are used so that visitors can interact with the content of different social platforms (facebook, youtube, twitter, linkedIn, etc..) and that are generated only for users of these social networks. The conditions of use of these cookies and the information collected are regulated by the privacy policy of the corresponding social platform.
