Cookies policy


A cookie is a small text file that is stored in your browser when you visit almost any web page. Its usefulness is that the web is able to remember your visit when I return to surf that page.

he purpose of the cookie is to adapt the web content to your profile and needs. Without cookies the services offered by any page would be significantly reduced.


Cookies do not usually store sensitive information about you, such as credit cards or bank details, photographs, your ID or personal information, etc. The data they save is of a technical nature, personal preferences, content personalization, etc. The web server does not associate you as a person but your web browser. In fact, if you usually surf Internet Explorer and try surfing on the same website with Firefox or Chrome you will see that the website does not realize that you are the same person because cookies are associated with the browser, not the person.


Below, we present a classification of the cookies commonly used according to different types depending on their person in charge, the time they remain and the purpose of their use:

  1. Types of cookies according to the entity that manages them:
    1. Own cookies: First-party cookies (also known as “HTTP cookies”) are small data packets that your web browser generates and exchanges with a dedicated web server. In return, only this server has access to its own cookie due to being the “first party.” This makes surfing the internet more enjoyable, because the website recognises you and automatically applies your desired settings and fills in your log-in data.
    2. Third-party cookies: Third-party cookies are installed by third-parties with the aim of collecting certain information from web users to carry out research into, for example, behaviour, demographics or spending habits. They are commonly used by advertisers who want to ensure that products and services are marketed towards the right target audience.
  2. Types of cookies according to the period of time they remain activated:
    1. Session cookies: Session cookies, also known as 'temporary cookies', help websites recognise users and the information provided when they navigate through a website. Session cookies only retain information about a user's activities for as long as they are on the website. Once the web browser is closed, the cookies are deleted. These are commonly used on shopping websites or e-commerce websites.
    2. Permanent cookies:Permanent cookies, also known as 'persistent cookies', remain in operation even after the web browser has closed. For example they can remember login details and passwords so web users don't need to re-enter them every time they use a site. The law states that permanent cookies must be deleted after 12 months.
  3. Types of cookies according to their purpose:
    1. Necessary cookies: These are the cookies that make a web page usable by activating basic functions such as navigation on the page and access to secure areas of the web page. The website cannot function properly without these cookies.
    2. Technical cookies: They are cookies that allow the user to navigate through a web page, platform or application and use the different options or services that exist there, such as, for example, control traffic and data communication, identify the session, remember the elements that make up an order, make the purchase process of an order, make the request for registration or participation in an event, use security elements during navigation, store content for the dissemination of videos or sound or share content through social networks.
    3. Personalization cookies: These are the cookies that allow the user to access the service with some predefined characteristics based on 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 location from where the service is accessed, etc.
    4. Analysis cookies: These are the cookies that allow the Editor to monitor and analyze the behavior of the users of the websites to which the cookies are linked. The information collected through this type of cookies is used in the measurement of the activity of the websites, application or platform and for the elaboration of user navigation profiles, in order to introduce improvements based on the analysis of the data of User use.
    5. Advertising cookies: These are the cookies that allow the management of the advertising spaces that the editor has included in a web page, application or platform from which it provides the requested service, based on criteria such as the edited content or the frequency in which the ads are displayed.
    6. Behavioral advertising cookies: These are the cookies that allow the management, in the most efficient way possible, of the advertising spaces that, where appropriate, the editor has included in a site, application or platform from which it provides the requested service. These cookies store information on the behavior of users obtained through the continuous observation of their browsing habits.
