1. What cookies are

Cookies are small files stored on your device when you visit a website. Among other things, they remember your preferences or keep a session open.

2. Cookies we use

This site uses a deliberately minimal set of cookies and similar storage. The following are technical (exempt from consent under Spanish LSSI art. 22.2 as strictly necessary):

  • Session cookie (tcst_session) and CSRF token (XSRF-TOKEN): keep your contact form session and protect forms against forgery. Duration: session / 2 hours.
  • Authentication cookie (admin panel only): keeps authorised staff signed in. Duration: session.
  • Consent preference (tc-cookie-consent, browser local storage): remembers your decision about this notice. Duration: until you clear it.

3. Analytics cookies (Google Analytics 4)

With your consent we use Google Analytics 4 (measurement ID G-ZGNTTG1KLW), a service of Google Ireland Ltd., to understand how the site is used. Its script and its cookies are loaded ONLY after you click "Accept" in the cookie banner. If you reject them or make no choice, nothing from Google is loaded and no analytics cookie is set.

The data is collected in aggregate: pages viewed, time on page, approximate location (city level), device and browser type and the source of the visit. Google Analytics 4 does not log or store IP addresses. We do not use the data for advertising and we do not combine it with the data you give us in a form.

Cookies used: _ga and _ga_[id] (they distinguish visitors; they expire 2 years after the last visit). Your consent choice is stored in your browser (local storage, tc-cookie-consent) until you clear it.

You can withdraw your consent at any time by clearing this site's data in your browser: the banner will appear again and you can reject analytics cookies. You can also install Google's opt-out browser add-on (tools.google.com/dlpage/gaoptout).

4. Managing cookies

You can change your decision at any time by clearing your browser data for this site (the banner will reappear). You can also configure your browser to block or delete cookies; see the help pages for Chrome, Firefox, Safari or Edge. Blocking technical cookies may break essential parts of the site, such as sending the contact form.
