Cookie policy

A cookie is a small file a website stores in your browser to remember something. Local storage (localStorage) does the same in another way. The law treats them alike: Article 22(2) of Spain's LSSI-CE requires sites to inform you and ask for your consent before using them, unless they're strictly necessary for the service you request.

The AEPD's Guide on the use of cookies (in Spanish), in the version updated in May 2024, applies those rules to any device that stores and retrieves data, not just classic cookies. That's why the table also lists what this site could store in local storage.

I use no advertising cookies, no social media pixels and no third-party plugins. Links to YouTube, Instagram or Discord are plain links: they load nothing from those platforms until you click. Fonts, video thumbnails and images are served from my own server.

Google Analytics is switched off and its code isn't loaded on any page. That's why you see no cookie banner and no “Cookie preferences” link in the footer: there's no cookie that needs your consent.

If I ever decide to measure visits, I'll do three things first: update this policy and the privacy policy with the cookie table and retention periods; show you a banner with Accept and Reject buttons of the same size and on the same level, as the AEPD guide requires; and set no analytics cookie until you accept. Continuing to browse won't count as acceptance, and you'll be able to change your mind at any time from the footer.

Your choice would be stored in your browser's local storage under the name ca-consent. It's a preference you choose and it serves only that purpose, so, under the AEPD guide's criteria for user-chosen preferences, it's exempt from consent.

Videos are embedded using YouTube's privacy-enhanced mode (youtube-nocookie.com). Before you press play you only see a thumbnail hosted on my server: neither the player nor any YouTube code is loaded.

When you press play, I load the player because you asked for it. From then on YouTube may use cookies or local storage in your browser under its own responsibility and according to Google's privacy policy. Google explains in its help on embedded videos that, in this mode, the view isn't used to personalize your YouTube experience or the ads you see outside this site.

The links to OKX, Ledger and Trezor are labeled “Advertising” and carry the rel="sponsored" attribute. Clicking one sets nothing from this site: it takes you to that company's website. Once there, the company may use cookies or an identifier included in the link itself to know you came from my site and pay me the commission, on top of the cookies it uses for its own purposes.

Those cookies belong to the company, not to me, and are governed by its cookie and privacy policy. It's the company that must inform you and, where required, ask for your consent on its website. If you don't want your visit linked to my referral, type its address straight into your browser: the price is the same. Why I use affiliate links and how I label them is explained in the legal notice.

You can also block or delete cookies from the browser itself, for example YouTube's or those of the websites you reach through a link. If you block everything, some websites will stop working properly; this one will keep working, because it doesn't need cookies to show you its content.

Retention periods, international transfers and how to exercise your rights are in the privacy policy; the owner's details are in the legal notice. If anything the site uses changes, I'll update this table first and, if needed, ask for your consent.
