Privacy and cookies

Last updated: 15 October 2026

In short

• No cookies, and nothing is written to your browser's storage, so there is nothing to accept.
• We count visits anonymously: no IP address is stored, and nothing lets us recognise you from one day to the next or follow you to other sites.
• If you email us, we use your message only to answer it.

Who is responsible

The controller of your personal data is Julio Barrera, the owner of this site (see the Legal notice). For anything about your data, write to [email protected].

What we process and why

Visit statistics

To learn which pages are read and how readers find them, we count visits with our own analytics service. It records the page visited, the site that sent you, your browser, device and language, and your approximate location, derived from your IP address. Your IP address isn't stored, and nothing lets us recognise you from one day to the next.

• Legal basis: our legitimate interest in knowing how the site is used (GDPR, art. 6.1.f).
• Retention: the statistics are kept while they are useful; backups, 60 days.
• Recipients: none. The data stays on the owner's servers in the European Union.

Hosting and security

The site is delivered by Cloudflare, which, like any web server, processes your IP address and request details to deliver the pages and to protect the site from attacks and abuse.

• Legal basis: our legitimate interest in delivering a secure site (GDPR, art. 6.1.f).
• Retention: short-lived security and traffic logs, kept by Cloudflare for the period its service sets.
• Processor: Cloudflare, Inc. (United States), under a data processing agreement. Transfers to the US are covered by the EU-US Data Privacy Framework, in which Cloudflare participates.

When you write to us

If you email [email protected], we receive your address, your name if you include it, and your message. We use them only to answer you and, when you report an error, to correct it.

• Legal basis: answering the request you send us (GDPR, art. 6.1.f).
• Retention: as long as needed to deal with your message and any follow-up correction; ask us to delete it at any time.
• Providers involved: Cloudflare forwards the email to the owner's inbox at Google (Gmail). Both companies are in the United States and participate in the EU-US Data Privacy Framework.

We never sell your data.

Cookies and browser storage

This site sets no cookies, and neither the site nor the analytics script writes anything to your browser's local or session storage. There is no advertising and no social media embed that could set them. That's why there is no cookie banner: there is nothing to consent to.

If that ever changes (for example, with advertising), this page will be updated first and we'll ask for your consent before setting anything that isn't strictly necessary.

Your rights

You can ask to access, correct or delete your personal data, to restrict or object to its processing, and to receive it in a portable format. Write to [email protected]; we'll answer within one month.

Keep in mind that the visit statistics are anonymous: since we don't store anything that identifies you, we usually can't find your visits in them.

If you think your data hasn't been handled properly, you can complain to the Spanish data protection authority, the Agencia Española de Protección de Datos (aepd.es).

Changes

If this policy changes, we'll update this page and its date.
