Data sources & privacy
The public breach list is fetched from haveibeenpwned.com (Have I Been Pwned) once a day by this site's data service, so your browser never contacts that service and it never sees your IP address. No input of yours is sent anywhere, nothing is stored, and descriptions are reduced to plain text before display.
To check whether your own email appears in a breach, use haveibeenpwned.com directly. This page never asks for an email address.
