What are cookies?
Cookies are files that can be downloaded to your computer by websites.
They are tools that play an essential role in the provision of many information society services. Among other things, 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, they can be used to recognise the user and improve the service offered.
Types of cookies
Depending on the entity that manages the domain from which the cookies are sent and processes the data obtained, two types of cookies can be distinguished:
• Own cookies o 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 o 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 the cookies.
In the event that the cookies are installed from a computer or domain managed by the editor itself but the information collected through them 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 they remain stored in the client’s browser, which may be:
• Session cookies o Designed to collect and store data while the user accesses a website. § They are usually used to store information that is only interesting to keep for the provision of the service requested by the user on a single occasion (e.g. a list of products purchased).
• Persistent cookies o 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 six types of cookies depending on the purpose for which the data obtained are processed:
• Technical cookies o Those that allow the user to navigate through a website, platform or application and the use of the different options or services that exist in it such as, for example, controlling traffic and data communication, identifying the session, accessing restricted access parts, remembering the elements that make up an order, carrying out the purchasing process of an order, making the application for registration or participation in an event, using security elements during navigation, storing content for the broadcasting of videos or sound or sharing content through social networks.
• Personalisation cookies o They allow the user to access the service with some characteristics of a general nature predefined according to a series of criteria in the user’s terminal such as for example would be the language, the type of browser through which you access the service, the regional configuration from where you access the service, etc.
• Analysis cookies o These allow the party responsible for them to monitor and analyse the behaviour 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 elaborationof browsing profiles of the users of these sites, applications and platforms, in order to introduce improvements based on the analysis of the usage data of the users of the service.
• Advertising cookies o They allow the management, in the most efficient way possible, of advertising spaces.
• Behavioural advertising cookies o They store information on the behaviour of users obtained through the continuous observation of their browsing habits, which allows the development of a specific profile to display advertising based on the same.
• External social network cookies o These are used so that visitors can interact with the content of different social platforms (facebook, youtube, twitter, linkedIn, etc…) and are generated only for users of these social networks
