Privacy Policy

Last updated: 29 October 2026

This tool runs entirely in your browser. The domains you enter or crawl are never sent to or stored on our servers — there is no account system and no database of your searches.

To verify domains, your browser contacts public third-party services directly: domain registries via the RDAP protocol (through the IANA bootstrap), Google Public DNS (dns.google), the Internet Archive (web.archive.org / archive.org), and — only when you use Crawl mode — a public CORS proxy (api.allorigins.win) to fetch the page you asked to crawl. Those services receive the domain names being checked, as is necessary for any domain lookup tool, and their own privacy policies apply to those requests.

This site may display advertising in the future (such as Google AdSense), which uses cookies to serve ads based on prior visits. You can opt out of personalised advertising at google.com/settings/ads.
