What data we process

The site has no user accounts or forms. Values you enter in the calculators are processed in your browser and are not sent to any server.

Visit statistics. We use Cloudflare Web Analytics to count visits in aggregate (page views, country, device type, performance). According to Cloudflare, it uses no cookies or local storage and does not build user profiles. The legal basis is our legitimate interest in understanding site usage to improve it (Art. 6(1)(f) GDPR).

Our hosting provider, Cloudflare, Inc., processes technical data (such as IP address and user agent) to deliver pages and protect them against abuse, based on the legitimate interest of providing a secure service (Art. 6(1)(f) GDPR). Cloudflare may process data outside the European Economic Area under the safeguards in its data processing agreement.

Advertising. If you accept in the consent message, Google Ireland Ltd. and its advertising partners process cookie or device identifiers, IP address and browsing data to serve and measure ads and, where applicable, personalise them. The legal basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time with the “Manage cookies” button. Google may transfer data outside the EEA under the safeguards in its terms. See Google’s privacy policy and our cookie policy.

If you email us, we use your address and message only to reply, and keep them only as long as needed for that purpose.

Your rights

You can exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to [email protected]. You may also lodge a complaint with the Spanish Data Protection Agency (aepd.es).

Changes

If the site adds analytics or advertising, this policy will be updated and your consent will be requested where the law requires it.
