Keystone customers say breach exposed data wallet maker promised to delete

The dispute matters because it turns a breach into a credibility test for Keystone's stated data-retention policy, not just a one-off security failure. Hardware wallet firms are trusted precisely because users assume minimal data trails; if the 180-day deletion promise is contested, that trust erodes across the category. The open question is whether Keystone can substantiate its retention claims, and whether other wallet makers face similar scrutiny over how long they actually keep customer information.
