What are cookies?
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 computer and, depending on the information obtained, can be used to recognize the user and improve the service offered.
Types of cookies
Depending on the entity that manages the domain from which cookies are sent and processes 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 publisher 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 publisher, but by another entity that processes the data obtained through cookies.
In the event that cookies are installed from a computer or domain managed by the publisher 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: designed to collect and store data while the user accesses a website. They are usually used to store information that is only of interest to keep for the provision of the service requested by the user on a single occasion (e.g. a list of purchased products).
- Persistent cookies: the data are still stored in the terminal and can be accessed and processed for a period defined by the person 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 is processed:
- Technical Cookies: those that allow the user to navigate through a web page, platform or application and to use the different options or services that exist therein, 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 purchase process of an order, applying for registration or participation in an event, using security elements during navigation, storing content for the dissemination of videos or sound or sharing 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, for example, the language, the type of browser through which the service is accessed, the regional configuration from which the service is accessed, and so on.
- Analysis Cookies: allow the person responsible for these, tracking and analyzing the behavior of users of websites to which they are linked. The information collected through this type of cookie is used to measure the activity of websites, applications or platforms and to create navigation profiles of users of these sites, applications and platforms, with the aim of introducing improvements based on the analysis of the data used by users of the service.
- Advertising Cookies: allow the most efficient management of advertising spaces.
- Behavioral advertising cookies: they store information on the behavior of users obtained through the continuous observation of their browsing habits, which allows the development of a specific profile to display advertising based on this.
