Corrections
A price, refund window or quote no longer matches the vendor's page? Send the tool's domain through the submit page — it queues the domain for a fresh read of the source pages, which is exactly what a correction needs.
Suggesting a tool
Same route: the submit page. Every suggestion goes through the same reading pipeline as any other domain — submitting is not a way to buy placement.
Privacy requests and everything else
The site stores almost nothing about you (see the privacy policy) — analytics can be blocked freely and submissions carry no identity. A published contact email is coming; until then, the channels above are the ones that exist, and we would rather say so than print an address nobody answers.
