Cookie policy
What gets stored in your browser, and why.
In short
This site runs without third-party cookies, tracking pixels or advertising. Nothing is loaded from someone else's server, no fonts, no scripts, no maps, unless you deliberately press a button that requires it.
Strictly necessary cookies
These are always set, because the site cannot work without them. They do not require consent under Article 22.2 of Spanish Law 34/2002 (LSSI-CE).
| Name | Purpose | Duration |
|---|---|---|
| `ecs_session` | Keeps your session while a form is being submitted and protects against CSRF | Until you close the browser |
| `ecs_lang` | Remembers the language you chose | 12 months |
| `ecs_consent` | Stores your answer to this notice so you are not asked again | 6 months |
Measurement cookies
The site uses two kinds of cookies.
Technical cookies (necessary). They remember your language and protect the forms. They are essential for the site to work and need no consent.
Google Analytics (analytics, optional). Only if you accept it in the cookie banner do we use Google Analytics 4 to measure, in aggregate and anonymously, how the site is used. It sets Google cookies (for example “_ga” and “_ga_…”) lasting up to 2 years. The provider is Google Ireland Limited and data may be processed on Google servers outside the European Economic Area, including the United States. Nothing is loaded or set until you accept, and you can change your mind at any time by reopening the cookie banner from the footer.
Changing your mind
You can change your preferences at any time from the "Cookie preferences" link in the footer. You can also clear cookies from your browser settings; the site will then ask for your language again.
