Privacy

What we collect

We do not use cookies for analytics, advertising, or visitor tracking. We do not operate a newsletter, user accounts, or any service that requires you to submit personal information.

The administrative section of this site uses a short-lived session cookie to authenticate editors. This cookie is not accessible to third parties and is discarded when the session ends.

Cloudflare

This site is served through Cloudflare's network. Cloudflare may log standard web request data, including IP addresses, request paths, and user-agent strings, as part of its infrastructure service. This data is subject to Cloudflare's privacy policy.

Cloudflare Turnstile is used on the administrative section to verify that requests come from humans rather than automated bots. Turnstile is a privacy-preserving challenge that does not require solving a visual puzzle and does not use behavioral fingerprinting for advertising.

If you contact us by email, we retain your message and email address only for the purpose of responding to your inquiry. We do not share this information with third parties or add you to any mailing list without explicit consent.
