Discovery 2026-10-08: DCR yes, CIMD yes, S256, public clients allowed. Superhuman is a mail client over the person's Gmail or Outlook account, so mail and calendar data reach Kipster through Superhuman's cloud; kept because it is the person's own Superhuman account rather than an aggregator, and flagged as a third-party data flow.",
