Records are indexed
Known breach disclosures, verified public archives, and trusted exposure feeds are normalized into a searchable index. Raw records are not displayed through the email checker.

How it works
A useful answer, without exposing the record.
The registry is designed around one question: can we help you understand possible exposure without making sensitive breach data more accessible?
An email is matched
Your search is normalized and compared against indexed identifiers. A result describes the source category and affected data types—not the underlying private information.
MatchingRisk becomes action
Each data type maps to specific guidance: changing reused passwords, securing recovery channels, enabling MFA, and watching for targeted follow-up attempts.
ResponseWhat a match means
Exposure is a signal, not proof of account access.
A match means an identifier associated with the email address appeared in a source indexed by the registry. It does not automatically mean the account is currently compromised.
The date attached to a source can also differ from the date the underlying incident occurred. Treat the result as a reason to review the account, not as a complete incident timeline.
Registry principles
Minimal disclosureShow enough to support action, never the exposed record itself.
Clear provenanceSeparate verified sources from unconfirmed exposure signals.
Practical guidanceTurn every finding into proportionate next steps.
