Privacy

Operator contact details are in the imprint.

Website checks

The tool sends your entered public host to the checking server. It discards paths, query parameters and fragments, resolves the host and makes a bounded request to its public root. The destination receives the checking server’s connection data. Do not enter a password, private link or confidential URL.

The checking code does not persist your input or result, download the page body or request microphone, camera or location access. Temporary limits in server memory protect availability. Hosting providers may process requests and technical security logs under their own policies.

Advertising and analytics

No advertising integration, central visitor tracker or cross-site function collector is active in this release. A non-sensitive completion event is available in page memory for later integration; it is not sent to a central service.

Hosting and your rights

Contact the operator using the imprint for personal-data information, correction, deletion or restriction requests, consent withdrawal or an objection where applicable. You can contact a data-protection authority.

Worker request boundaries

The backend obtains A and AAAA records through Cloudflare DNS and connects only to a validated public numeric IP, retaining the original hostname for HTTP and TLS. Every redirect is revalidated. No browser cookies, credentials or referrer are forwarded. TLS socket failures and unsupported destinations remain inconclusive; no insecure or unpinned fetch fallback is made. Peer certificate issuer and expiry are unavailable in this transport. The app retains only short-lived capacity counters in an isolate, not a persistent URL history. Counter scope is one isolate and is not a global rate limiter.

Hosting and optional advertising

This website is delivered through Cloudflare Pages, operated by Cloudflare, Inc., USA. Page requests necessarily disclose technical connection data such as IP address, requested URL, time and browser information to the host for delivery, security and diagnosis. Our legal basis is Art. 6(1)(f) GDPR, our interest in providing a secure, functioning free tool. Cloudflare may process hosting data internationally; see its privacy policy for processing, retention and international transfers.

No external advertising or analytics loader is included in this release. Advertising remains unavailable until this exact new host has an approved placement and the integration and disclosures are updated. There is no active advertising integration or recorded revenue implied by this package. The complete tool is available without advertising. Operator contact is in the imprint.
