Privacy
Last updated 2026-09-25. Short version: there are no accounts, no passwords, no cookies set by this site, and no tracking of you across other sites.
What is collected
- The URL you ask about. It is the input, so it is necessarily processed, and it is written into the proof record, which is public and permanent at its own address.
- Operational logs. Each proof writes one line naming the host asked about, the verdict and timings. The log line never contains an IP address.
- Rate limiting state, keyed on a form of the connecting address, so one caller cannot aim the service at one site repeatedly. It is short lived and is not used for anything else.
What is not collected
No account, no email, no password, no payment details, and no advertising or cross site tracking. This site sets no cookies of its own.
Who else sees the URL you ask about
Proving a domain necessarily tells the public resolvers and registries involved which domain was asked about: Cloudflare DNS, Google's resolver, and rdap.org. The report names its sources. Cloudflare serves this site and sees requests as its network operator.
Proof records are public and permanent
A record lives at an unguessable address and is not listed anywhere, but anyone holding the link can read it. Do not prove a URL you would not want quoted.
