Not a promise. A mechanism.
Most domain search tools quietly check availability through the registrar you'd eventually buy from. That's convenient for them and risky for you: the same company has both the data and an incentive to act on it before you do.
Snooplr never asks a registrar at all. Every TLD has its own authoritative registry — the actual source of truth for whether a domain is taken — and each one exposes a standard lookup protocol called RDAP. We query that directly, using IANA's official bootstrap file to find the right registry server for whatever TLD you're checking, instead of relying on a single third-party convenience redirector. If the authoritative server doesn't answer, we fall back to a public RDAP gateway as a last resort — and if neither gives a clear answer, we say so. We never guess "available" just because a check failed.
Every lookup goes directly to the authoritative registry server — not through a registrar. There's no search history on our end, and registrars only find out when you actually register.
The last piece is what we don't keep. Our search log records that a search happened and when — never which domain. There's no column for it in the database. We can't sell what we don't have, and we can't lose it in a breach either.
None of this requires you to trust a privacy policy. The mechanism is the policy.
