Are you the maker? Respond to this finding

Free. There is no paid or faster path, and nothing about a rating is for sale. Prove you control your company's domain with one DNS record; a person then reads your statement beside our finding and decides whether to publish it.

An email is encrypted at rest and opened only to answer you; it is erased 30 days after we resolve this (or 180 days if still open), and you can erase it sooner. Unproven filings are deleted after 14 days.

Think something here is wrong?

Evidence and research improve when people push back. Tell us what to re-check — a misattributed domain, an outdated classification, a claim about your own app — and a human will review it. Responses can take up to 30 days.

If you leave an email it is encrypted at rest and opened only to answer you — never shared, never used for anything else. It is erased 30 days after we resolve this (or 180 days if it is still open) without you asking, and you can erase it sooner at any time; either way your correction stays, anonymously. Leave it blank and your request is fully anonymous from the start (we store no IP address either way).
