Summary: This website uses necessary technical cookies and, with prior consent, analytics cookies from Google Analytics 4 (GA4) and advertising cookies from Google Ads. When visiting the site for the first time, a banner is displayed to accept or reject these cookies. If you reject, Google operates in cookieless mode (cookieless) without storing or reading data from your device. You may change your preference at any time by clearing the site data from your browser.
What are cookies?
Cookies are small text files that websites store on the user's device (computer, mobile phone, tablet) when they visit them. These files allow the site to remember information about the visit, such as preferred language or other settings, with the aim of facilitating the browsing experience and making the site work more efficiently.
There are different types of cookies according to their purpose, origin, and duration:
- By purpose: technical/necessary, preferences, analytics or statistics, and marketing or advertising.
- By origin: first-party (issued by the website itself) or third-party (issued by external domains).
- By duration: session (deleted when the browser is closed) or persistent (remain for a defined period).
Applicable regulatory framework
This Cookies Policy is drafted in compliance with the following regulations:
- Art. 22.2 of Law 34/2002 (LSSI-CE), on Information Society Services and Electronic Commerce, which requires the user's informed consent for the use of cookies that are not strictly necessary.
- Directive 2009/136/EC ("e-Privacy Directive"), which amends Directive 2002/58/EC on privacy in electronic communications.
- Regulation EU 2016/679 (GDPR), regarding the processing of personal data derived from the use of cookies.
- Guide on the use of cookies from the Spanish Data Protection Agency (AEPD), updated 2023 edition.
Strictly necessary technical cookies are exempt from the consent requirement in accordance with recital 25 of the e-Privacy Directive and the AEPD's interpretation. The remaining cookies require the user's prior, free, specific, informed, and unequivocal consent.
