ozen is built so meeting audio never leaves your Mac: no bot joins the call, and transcription and speaker recognition run locally. You’re still recording people, so a few things are on you.
Recording others
- ozen records and transcribes other people. Tell participants, and follow your local recording laws. Some places require everyone’s consent.
- In Always mode the mic records everything said near the Mac, not only meetings. Use Meetings mode or places to limit it.
Voiceprints are biometric data
- Keep the voices registry repository private.
- Enroll only people who agreed. Remove someone with
delete_person(see MCP server) and from the registry. - Ignored voices never go to the registry.
What leaves your Mac
| What | Where | When |
|---|---|---|
| Names and voiceprints | Your voices registry git remote | After tagging, and when pulling updates |
| Map tiles for the area shown | OpenStreetMap | Only while the Places map is open |
| Model downloads | Hugging Face and similar | First use of each model |
| Transcripts you hand to an agent | That agent’s AI provider | When you use Ask AI, Open, or MCP |
Your location, recordings, transcripts, fixes and screenshots otherwise stay on the Mac. Remember that the last row means cloud agents like Claude Code send what they read to their provider.
places.json holds where you live and work. Don’t copy it into shared folders.
