What leaves your Mac
Two providers. Two narrow jobs.
Deepgram receives audio. Anthropic receives transcript text. Those are the only companies asked to make sense of the conversation; the transcript passes through a Cloudflare-hosted relay that does not retain it.
01 · audio
Deepgram
Transcribes the recording and separates the two speakers. Audio travels directly from the app to Deepgram using a short-lived token.
- BetterTalk infrastructure never receives the audio
- Every request opts out of model improvement
- Live and final transcription only

Anthropic
Analyzes speaker-labelled transcript turns to produce structured observations. No BetterTalk account, couple, device, email, billing, invitation, or session identifier is included.
- Transcript text is not anonymous by itself
- Standard commercial API retention is up to 30 days
- No Files, batch processing, prompt caching, or Workbench
Read Anthropic's commercial retention policy ↗The honest limits
Private does not mean anonymous or magical.
Removing account identifiers does not make spoken words anonymous. A conversation may name people, places, employers, diagnoses, or other identifying details.
BetterTalk makes an operational promise, not a cryptographic impossibility claim: no product or support path retrieves conversations, no BetterTalk storage retains audio or transcripts, and the control plane rejects content-bearing metadata.
Like any networked app, BetterTalk depends on your Mac, your network, and its service providers staying secure. No digital service can promise perfect security.
