Privacy policy

Data controller

The controller of the personal data collected on this site is Glauc Fornés Gil (Barcelona, Spain). You can exercise any right or make any enquiry through the Site’s contact form.

What data we process and why

Contact form: name, email address and message. Purpose: answering your enquiry. The message is delivered to the owner by email and is not stored in any database of the Site.

Newsletter (“Notes by email”): email address and preferred language. Purpose: sending you newly published notes. Legal basis: your consent when subscribing, which you can withdraw at any time by replying to any email or via the contact form.

No other personal data is processed: the calculation tools run in your browser and neither send nor store anything you enter.

Legal basis and retention

The legal basis for all processing is the data subject’s consent (art. 6.1.a GDPR). Newsletter data is kept for as long as the subscription lasts; contact-form data for the time needed to handle the enquiry.

Recipients and transfers

Data is neither shared with third parties nor transferred outside the European Union. The Site is hosted on Hetzner Online GmbH servers located in the European Union (Finland), under the standard hosting data-processor relationship.

Cookieless analytics

The Site uses Umami, an open-source analytics system self-hosted by the owner on the same server. It uses no cookies, collects no personal data or identifiers, performs no cross-site tracking, and all metrics are aggregate and anonymous. That is why no consent banner is required.

Cookies and local storage

The Site uses no cookies. It only uses the browser’s local storage (localStorage) to remember your light/dark theme preference — a value that never leaves your device and is exempt from consent.

Your rights

You may at any time exercise your rights of access, rectification, erasure, objection, restriction of processing and portability through the contact form. You also have the right to lodge a complaint with the Spanish Data Protection Agency (aepd.es) or your local supervisory authority.
