This page details how the privacy of personal data is handled within HIBP and what information is collected when you use the service. </p> Breach data stored in HIBP <p> When a data breach is loaded into HIBP, the email addresses are stored in the online system. In some cases, phone numbers may be loaded in separately where they exist in an isolated data store not attached to any other personally identifiable information (i.e. not next to corresponding email addresses). No other data of any kind (names, phone numbers, etc) are stored on data load. HIBP also stores a list of data classes that were impacted in each breach.
