This is a translation for information only. In case of any discrepancy, the Spanish version prevails.

1. What cookies are

A cookie is a small file that a website stores in your browser. It is used to remember information about your visit: preferences, session or usage statistics.

2. What cookies we use today

This site sets no cookies of its own. The only ones that may ever be set are those of the analytics tool described below, and only if you accept it. Until you do, none are set.

Your answer is stored in your own browser, not in a cookie, and you are asked again after 12 months.

3. Analytics: Microsoft Clarity and Google Analytics 4

We use Microsoft Clarity and Google Analytics 4. They record in pseudonymised form how the site is used — clicks, scrolling, movement between pages and where each visit comes from — so we can spot what does not work and fix it.

The Clarity script is not even downloaded until you accept it: if you say no, your browser never connects to Microsoft. Nor do we authorise advertising storage, because we do not advertise. If you do not accept, the site works just the same.

These are the cookies Clarity may set, according to Microsoft’s documentation:

Cookie	Type	Purpose
_clck	first-party	Clarity user ID
_clsk	first-party	Links page views into one session
CLID	third-party	First time Clarity saw this user
ANONCHK	third-party	Microsoft technical flag
MR	third-party	Whether to refresh MUID
MUID	third-party	Identifies browsers across Microsoft sites
SM	third-party	Synchronises MUID across Microsoft domains
_ga	first-party	Tells visitors apart
_ga_<ID>	first-party	Keeps the session state

4. How to accept, refuse or change your mind

On your first visit you will see a notice to accept or refuse it, with both options one click away. You can change your choice at any time below.

You can also manage or delete cookies from your browser settings. Note that blocking all cookies may affect how other sites work.
