What a cookie is
A small file a website stores in your browser so it can recognise it on later visits. Two different things are used here: your browser's own storage so the site works, and Google Analytics cookies to measure usage. Only the second kind needs your permission.
Necessary storage
The light or dark theme, the language you picked, the boxes you tick in the document lists and your decision about this policy are kept in your browser's local storage. They never leave your device and are not shared with anyone. They are strictly necessary to provide the service you asked for, so they are exempt from consent under article 22.2 of the Spanish LSSI.
Analytics cookies
Google Analytics 4 tells us how many people look up each procedure, which language they arrive in and which guides they leave. That is what lets us decide what to update first. Nothing is installed until you press “Accept”, and if you reject, the script is never loaded and no data is sent.
- _ga — Tells visitors apart. Set by Google Analytics. (2 years)
- _ga_<ID> — Keeps the state of the measurement session. Set by Google Analytics. (2 years)
Who processes the data
Analytics is run by Google Ireland Limited, and the data may be processed in the United States by Google LLC under the EU-US Data Privacy Framework and standard contractual clauses. See Google's privacy policy for how they use it. Google's privacy policy

You can also delete or block cookies from your browser settings. If you block them entirely, the site still works exactly the same.
