Cookie policy
Last updated: 1 November 2026
This site uses analytics cookies to understand how visitors use it, so I can improve it. They are only set if you accept them. If you reject them, or don't choose, the site works exactly the same and no analytics tool is loaded.

Without consent, the site only stores your choice (cookie-consent) in your browser's local
storage, so that it doesn't ask you again. This is necessary for the consent to work and is never sent anywhere.
What is collected
Google Analytics records which pages are visited, how visitors arrived, and general information about the device, browser and approximate location (country or city). Microsoft Clarity records how the page is used (clicks, scrolling and mouse movement) to produce heatmaps and session replays; text typed into the page is masked. I use this information only in aggregate, to see how the site is used. I don't use it for advertising or to identify anyone.
Legal basis and retention
The legal basis is your consent (Article 6(1)(a) of the GDPR and Article 22(2) of the Spanish LSSI). You can withdraw it at any time with the button above or the “Cookie settings” link at the bottom of the home page; the analytics cookies are then deleted. Google Analytics keeps the data for up to 14 months and Microsoft Clarity for up to 13 months.
Who receives the data
Google LLC and Microsoft Corporation process the data as providers of these tools. Both may transfer it to the United States, and both are certified under the EU-US Data Privacy Framework. See their policies: Google and Microsoft.
Your rights
You can ask to access, correct or delete your data, object to its processing, or ask to restrict it, by writing to psnunez@bib.uc3m.es. If you think your data has not been handled properly, you can complain to the Spanish Data Protection Agency (aepd.es).
