This page explains how we use personal data when you visit metalaxis.net, sign up to hear from us, or use our free tools.
Who we are
We are metalaxis s.r.o., Nové sady 988/2, 60200 Brno, Czech Republic. To ask about this policy or your data, email [email protected].
Newsletter and free guide
If you sign up for our newsletter or free guide, we collect your email address and first name. We use Brevo (Sendinblue SAS, in the EU) to manage the list and send the emails.
We only add you after you confirm your email (double opt-in). The legal basis is your consent. You can withdraw that consent at any time: every email includes an unsubscribe link, or you can email us.
We keep your email address and first name until you unsubscribe.
Website analytics
We use Google Analytics 4, through the MonsterInsights plugin, to understand how this website is used — for example, which pages are visited and whether a file is downloaded.
Free tools
Our free tools are on a separate site, tools.metalaxis.net. You can run the self-checks without creating an account.
Some tools offer an optional AI explanation of your results. If you choose it, only the self-check answers and the activity details needed for that explanation are sent to Groq (Groq, Inc., USA), which processes them to generate the explanation. This step is optional; you can use the tools without it.
Some tools also let you optionally send us a review request. If you do, only what you type into the request — for example your email address and your question — is stored in a Google Sheet (Google). Nothing else is collected for that request.
Your rights
Under the GDPR, you can ask us to access, correct or erase your personal data, or object to our use of it. Email [email protected] and we will respond.
You also have the right to complain to the Czech data protection authority, the Úřad pro ochranu osobních údajů (ÚOOÚ): uoou.gov.cz.
