What is stored in your browser and what you can switch off
This website does not install any third-party cookies until you accept them. If you do not accept, the website works just the same: the only thing lost is knowing which pages are useful.

This is a translation for convenience. If it differs from the Spanish version, the Spanish version prevails.
What a cookie is
A cookie is a small file that a site stores in your browser to remember something from one visit to the next. There are similar technologies, such as local storage, that do the same thing without being cookies; this policy treats them in the same way, because they affect you in the same way.
The ones we use without asking your permission
They are technical and preference cookies: without them the site would not work, or would work less well. Article 22.2 of Ley 34/2002 allows them to be used without consent, and they say nothing about you.
| Name | Type | Purpose | Duration |
|---|---|---|---|
gs-tema |
Local storage, first-party | Remembering whether you chose light or dark mode, so that the page does not flicker when it loads | Until you clear your browser data |
gs-idioma |
Local storage, first-party | Remembering the language you chose in the selector, so that the website opens in that language next time | Until you clear your browser data |
The ones we only use if you accept
They are analytics cookies and belong to a third party, Google. They are not loaded when you arrive: the Google Analytics code is not even downloaded until you click “Accept” in the notice. If you do not, or if you reject it, none is installed.
| Name | Provider | Purpose | Duration |
|---|---|---|---|

Google Ireland Limited | Telling one visit apart from another to count how many different people come to the site | 2 years |
_ga_D96VY2W6Z9 |
Google Ireland Limited | Keeping the state of the analytics session | 2 years |
Analytics data may be processed outside the European Economic Area. The terms of those transfers are set out in the privacy policy.
What you will not find here
- There are no advertising or social media cookies.
- There are no third-party tracking pixels.
- We do not sell or share with anyone what you do on this website.
- Fonts and icons are served from our own server, not from an external content delivery network, so loading the page does not tell anyone about your visit.
How to change your mind
You can withdraw your consent or give it again whenever you like from the cookie settings link in the footer of any page. Once you withdraw it, the analytics cookies stop being used.
You can also delete or block them from your browser. Each browser calls it something different, but it is always in the privacy settings: Chrome, Firefox, Safari and Edge let you see a site’s cookies and delete them.
Changes
If we add or remove cookies, we update this page and its date, and we ask you again when the change affects the ones that need your permission.
