Cookie policy

1. What are cookies?

Cookies are small text files that websites send to your device when you visit them and that are stored in your browser. They make it possible to remember information about your visit, facilitate navigation and, in some cases, measure use of the site.

2. Cookies used on this site

This website is designed with a privacy-by-default approach. We currently do not use any analytics, advertising or tracking cookies from third parties.

The only cookies or local storage we use are:

• certens-theme — first-party localStorage. Stores your light/dark theme preference. Purely technical. No consent required.
• Cloudflare Turnstile cookies — loaded only when you interact with the contact form, with the sole purpose of protecting the form against automated use (anti-bot). Their use is technical, strictly necessary for the form to work and, under article 22.2 of the Spanish LSSI-CE and the Spanish DPA's criteria, does not require prior consent.

3. How to manage cookies

You can configure your browser to accept, reject or delete cookies. Instructions depend on the browser you use:

• Google Chrome
• Mozilla Firefox
• Safari
• Microsoft Edge

4. Changes to the policy

We reserve the right to modify this policy to adapt it to legislative changes or technical improvements. Any modification will be published on this same page indicating the update date.
