Data Protection

Tamper-evident audit log. A chained record of every transcription.

Every transcription is recorded in a chained audit trail. Entries are linked with SHA-256 checksums, which makes edits to past entries detectable. Export the full log as JSON for compliance reviews.

  • SHA-256 hash chain, each entry is linked to the previous one, making edits to past entries detectable
  • Design assertion, each entry carries the app's no-outbound design assertion for the transcription path
  • Compliance export, one-click JSON export for compliance reviews
  • 100% on-device processing, no audio or transcript data ever leaves your machine
  • Chain verification, built-in integrity check validates the linkage of the recorded entries
  • Encrypted backup & restore, create encrypted backups of your transcription database and restore on any device, keeping patient data safe and portable
