3. Information we collect

3.1 Hosting and security (Cloudflare)

The Site is hosted and delivered by Cloudflare, Inc. When you visit, Cloudflare processes technical data such as your IP address, browser type, the page requested, and the time of the request. This is needed to deliver the Site, protect it from abuse, and keep it working. Cloudflare may also obfuscate email addresses on our pages to protect them from spam bots.

Legal basis (EU/UK): our legitimate interest in operating a secure website (GDPR Art. 6(1)(f)).

3.2 Privacy-friendly statistics (Plausible)

We count visits with a self-hosted instance of Plausible Analytics. Plausible does not use cookies and does not store your IP address or any identifier that follows you across sites. We only see totals such as page views, referring sites, country, and device type.

Legal basis (EU/UK): legitimate interest in understanding how the Site is used (GDPR Art. 6(1)(f)).

3.3 Settings saved on your device

We save your preferences (such as your test results, round history, labels and an unfinished setup comparison) in your browser's local storage so they are remembered next time. This data stays on your device. You can delete it by clearing your browser's site data.

3.4 When you contact us

If you email us, we receive your email address and message. We use them only to reply and delete them when they are no longer needed, usually within 12 months.

Legal basis (EU/UK): legitimate interest in answering your request (GDPR Art. 6(1)(f)).

4. Cookies

The Site does not set cookies.

5. Who we share data with

We share data only with the service providers named above, and only as needed for the purposes described. We do not sell your personal information. Some of these providers are located in the United States. Where data is transferred outside the EU/UK, the providers rely on safeguards such as the EU-U.S. Data Privacy Framework or Standard Contractual Clauses.

6. Your choices and rights

  • EU, EEA, UK, and Swiss residents: you have the right to access, correct, delete, or restrict the use of your personal data, to object to processing based on legitimate interest, to data portability, and to withdraw consent at any time. You can also complain to your local data protection authority.

7. How long we keep data

  • Server and security logs at Cloudflare: kept by Cloudflare for a limited period under its own policies.
  • Plausible statistics: aggregated totals only, kept while the Site exists.
  • Emails: usually up to 12 months after the conversation ends.

8. Children

The Site is intended for a general audience and is not directed at children under 13 (or under 16 in the EU). We do not knowingly collect personal information from children. If you believe a child has sent us personal information, contact us and we will delete it.
