Cookie policy
This is a courtesy translation. In the event of any discrepancy, the Spanish version prevails.
What a cookie is
A cookie is a small file that a website stores in your browser. It is used to remember information between pages — the language you chose, for instance — or to measure how the site is used.
Which cookies we use
This site uses four cookies. Two are necessary for it to work and are always set; the other two are analytics cookies and are only set if you accept them. We use no advertising or profiling cookies, and we pass no data to advertising networks.
| Cookie | Set by | Purpose | Duration |
|---|---|---|---|
pll_language | This site | Remembers the language you chose so it is not asked again on every page. | 1 year |
ddua_consentimiento | This site | Stores whether you accepted or rejected analytics cookies, so the notice is not shown again. | 1 year |
_ga | Distinguishes visitors from one another so the number of distinct people can be counted. | 2 years | |
_ga_JNPJS6BDWX | Keeps the Google Analytics 4 session state. | 2 years |
Necessary cookies
pll_language and ddua_consentimiento are strictly necessary: without the
first, the site would not know which language to show; without the second, you would be asked about
cookies on every page. As they are essential to providing the service you requested, they do not
require consent under article 22.2 of the Spanish information society services act.
Analytics cookies
We use Google Analytics 4 to learn which pages are useful and which are not. It runs with Google consent mode and IP anonymisation: until you accept, no cookie is set and no identifiable data is sent. These cookies are controlled by Google Ireland Limited; see their privacy policy.
Accepting, rejecting or changing your mind
On your first visit you will see a notice with two buttons of the same size: accept and reject. You can change your decision at any time from the «Cookie preferences» link in the footer. Rejecting does not limit your use of the site: everything works the same.
You can also delete or block cookies from your browser settings (Chrome, Firefox, Safari, Edge).
Updates
If we add any tool that sets cookies, this page will be updated and your consent will be requested again. Last updated: September 2026.
