Cookie policy
Which cookies and similar technologies this site uses, who sets them, how long they last and how to change your choice.
Last updated: 14 October 2026
This is a translation of the Spanish cookie policy. In case of discrepancy, the Spanish version prevails.
1. What cookies are
They are small files a website stores in your browser to remember information between visits. Here we also include similar technologies, such as the browser’s local storage.
2. Cookies this site uses
Necessary ones always work because without them the site cannot work or protect itself. Analytics ones are only stored if you accept them in the banner.

3. Google Analytics without cookies
If you do not accept analytics cookies, Google Analytics stores nothing in your browser and does not recognise you from one visit to the next (the random number sent with the signals changes every time a page loads), but it receives technical signals for each page view and for some interactions, such as opening a question or moving through the form (the page, the action, the browser type and the time; the IP address reaches it through the connection itself) to estimate overall visits. This is Google’s consent mode (Consent Mode).
4. Google map
The contact page does not load Google Maps until you click the map button. When you click it, Google may set its own cookies, which it explains in its policy (policies.google.com/technologies/cookies).
5. Marketing cookies
The site does not use advertising cookies today. The preferences panel includes this category in case any are added; if it were ever used, we would update this policy and ask for your permission again.
6. How to change or withdraw your consent
Click the ‘Cookies’ button in the bottom-left corner of the screen to open the preferences panel and change your choice whenever you like: rejecting is as easy as accepting.
If you withdraw your consent, analytics cookies already stored stop being used, but they stay in your browser until they expire or you delete them.
You can also delete cookies in your browser settings.
7. More information
How we handle your personal data is explained in the privacy policy.
