Cookie policy

Cookies are small text files a website stores on your device when you visit it. They allow information about your visit to be remembered, such as your language or a signed-in session. Browser local storage (localStorage) does a similar job — saving something on your device to remember it on your next visit — so we treat it under the same rules.

We use Vercel Analytics to know how many visits the site gets and which pages get read the most. It is active for everyone, with no permission asked, for a specific and verifiable reason: it uses no cookies and stores or reads nothing on your device. There is therefore no storage that would require your consent under article 22(2) of the LSSI-CE.

Vercel Inc., which already processes technical data as a processor for hosting this site (see the Privacy policy, section 5), processes these visits in an aggregated, statistical way: it does not tie them to your identity or track you across other websites.

Article 22(2) of Spanish Law 34/2002 (LSSI-CE) requires consent to store information on a user's device, except where that information is strictly necessary to provide a service expressly requested by the user. Remembering the language you chose in the header selector is exactly that: a service you asked for by using the selector. The cookie is first-party, identifies nobody, is shared with nobody and cannot be used to profile anyone. It is therefore exempt from consent, and asking for it would be inappropriate.

Today this website has NO Google tool connected: no Google Analytics, no Google Ads, no other service that depends on Google Tag Manager. There is no Google identifier anywhere in the code and no Google cookie in your browser.

If it is ever connected, it will not switch on all at once. Before anything from Google loads, a notice will appear with two equally visible options, "Accept" and "Reject", with neither hidden nor made more prominent than the other. Nothing from Google loads until you press "Accept"; if you press "Reject", or if you simply keep browsing without choosing, nothing loads — continuing to browse without choosing does not count as accepting.

Your choice is saved in your own browser (localStorage, not a cookie), together with the date and the version of this notice you decided under, so that what you accepted or rejected, and when, can be demonstrated. That record never leaves your browser: it is not sent to any server of ours. It is valid for 12 months; after that, or if what is being asked changes materially, you will be asked again. That record of your own choice is, in turn, itself exempt from consent under the same article 22(2): it is strictly necessary to be able to respect the decision you yourself made.

Technically, this is implemented with Google's "Consent Mode v2": the default state — before you decide anything — is denied for the four signals Google Tag Manager checks (ad_storage, ad_user_data, ad_personalization and analytics_storage), and they only turn to granted if you accept.

A permanent link in this page's footer, "Cookie preferences", will let you review or change your decision at any time, as often as you like. That link, like the rest of what is described in this section, only appears once Google Tag Manager is actually connected.

You can delete or block the language cookie from your browser settings. If you do, the site will keep working normally: it will simply stop remembering your language and will serve you Spanish, which is the default.

• Edge: Settings → Cookies and site permissions.

For the Google part, if it is ever activated: use the "Cookie preferences" link in the footer, described in section 4.

If any of the above were to change — in particular, if Google Tag Manager is connected — we would update this page and the last-updated date in the header.
