Privacy and cookie policy

Last updated: October 18, 2026.

In short: GrillMath has no accounts, no forms, no analytics and no advertising, and it doesn't set any cookies. The calculators run in your browser and what you type into them is not sent to us.

2. What data we process

  • Connection data. When you visit the site, our web server automatically logs your IP address, browser, the page requested and the date and time. We use these logs only to run the site, keep it secure and fix errors, and they are deleted periodically. Legal basis: our legitimate interest in operating a secure website (art. 6(1)(f) GDPR).
  • Emails. If you write to us, we use your email address and message only to reply to you. Legal basis: your request and our legitimate interest in answering it.

We don't sell or share personal data with anyone, except where required by law. Our hosting provider processes it on our behalf only to provide its service.

3. Cookies and browser storage

This site doesn't use cookies, analytics or advertising trackers, and it doesn't load scripts or fonts from third parties.

If you switch between light and dark mode, your choice is saved in your own browser's local storage (grillmath-theme) so the site remembers it. It is never sent to our server, and you can delete it from your browser settings at any time.

If we ever add advertising, analytics or affiliate links that use cookies, we will update this policy first and ask for your consent where the law requires it.

4. Your rights

Under the EU and UK General Data Protection Regulation you can ask us 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 info@realwigo.com.

You can also lodge a complaint with a data protection authority: in Spain, the AEPD; in the United Kingdom, the ICO.

5. Children

The site is meant for a general audience and doesn't knowingly collect data from children.
