A cookie is a file that is downloaded to your computer when you access certain web pages. Cookies allow a website to, among other things, store and retrieve information about the browsing habits of a user or their computer and, depending on the information they contain and the way they use their computer, may be used to recognize the user.



1. Types of cookies according to the entity that manages them.

Depending on the entity that manages the computer or domain from which the cookies are sent and treats the data obtained, we can distinguish:

  • Own Cookies: These are cookies that are sent to the user’s terminal equipment from a computer or domain managed by the publisher itself and from which the service requested by the user is provided.
  • Third party cookies: These are 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.

2. Types of cookies according to the length of time they remain activated.

Depending on the length of time they remain activated in the terminal equipment we can distinguish:

  • Session Cookies: A type of cookie designed to collect and store data while the user is accessing a web page. They are usually used to store information that is only of interest for the provision of the service requested by the user on a single occasion (e.g. a list of products purchased, shopping cart….).
  • Persistent Cookies: They are a type of cookie in which the data is still stored in the terminal and can be accessed and processed for a period defined by the person responsible for the cookie, ranging from a few minutes to several years (e.g. they are used to maintain the password over successive sessions and thus facilitate the purchase and registration services).

3. Types of cookies according to their purpose.

Depending on the purpose for which the data obtained through cookies is processed, we can distinguish between:

  • Technical Cookies: These are those that allow the user to navigate through a web page, platform or application and use the different options or services that exist on 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, making the purchase process of an order, making the request 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: These are those that 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 used to access the service, the regional configuration from which the service is accessed, etc.
  • Analysis Cookies: Cookies that allow the person responsible for them to track 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 to create navigation profiles of the users of these websites, applications and platforms, in order to make improvements based on the analysis of the data used by the users of the service.
  • Advertising Cookies: These are those that allow the management, in the most efficient way possible, of the advertising spaces that, where appropriate, the publisher has included in a web page, application or platform from which the requested service is provided based on criteria such as the edited content or the frequency with which the ads are displayed.
  • Behavioural advertising cookies: These are those that allow the most efficient management of the advertising spaces that, where appropriate, the publisher has included in a website, application or platform from which the requested service is provided. These cookies store information on the behaviour of users obtained through the continuous observation of their browsing habits, which allows them to develop a specific profile to display advertising based on it.
