Cookie policy

Cookies are small files a website stores in your browser. We only use the ones the site needs to work: no analytics, no advertising, no social media.

That is why we don’t show a consent banner: technical cookies and cookies that store a preference you choose are exempt (article 22.2 of Spanish Law 34/2002).

02Browser local storage

The site also stores in your browser (localStorage) the articles you mark with “Save for later” and your progress through guide steps. That data never leaves your device and is not sent to our server.

03Third-party cookies

We don’t use any. Links to other sites (sources, repositories) are governed by their own policies.

04How to delete or block them

You can delete or block cookies in your browser settings. If you block NEXT_LOCALE the site still works but won’t remember your language. More in the privacy policy.
