This information does not reveal your identity or any personal data, nor does it access the content stored on your computer, but it does allow our system to identify you as a specific user who has visited the website before, viewed certain pages, etc. and also allows us to save your personal preferences and technical information such as the visits made or specific pages you visit.

In compliance with Directive 2009/136/EC, implemented in our legislation by the second paragraph of Article 22 of the Law on Information Society Services, following the guidelines of the Spanish Data Protection Agency, we proceed to inform you in detail of the use made of our website.

With regard to third-party cookies, i.e. those that are not part of our website, we cannot be held responsible for the content and veracity of the privacy policies that they include, so the information we offer you is always with reference to the source.

Below, cookies are classified according to a series of categories. However, it should be noted that the same cookie may be included in more than one category.


– Own cookiesThese are 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 cookiesThese are sent to the user's terminal equipment from equipment or a domain that is not managed by the publisher, but by another entity that processes the data.

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 these 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.

These cookies store information on the behaviour of users obtained through the continuous observation of their browsing habits, which allows a specific profile to be developed in order to display advertising based on the same.
