Privacy Policy

Last updated: March 2026

Our Principle

FiftyX is designed around a simple idea: keep less, not encrypt more. Audio is ephemeral. Only text survives. Everything runs on your Mac.

What We Collect

Audio (temporary)

FiftyX records system audio and microphone input while running. Audio files are stored locally on your Mac and automatically deleted at the end of each day (midnight by default, configurable). Audio is never uploaded to any server.

Transcripts and Summaries (persistent)

Speech is transcribed on-device using WhisperKit. Transcripts, meeting summaries, action items, and voice profiles are stored locally in your Mac's application data. These persist indefinitely so you can search your conversation history.

Voice Profiles (persistent)

Speaker embeddings (numerical voice fingerprints) are stored locally to identify speakers across meetings. These are mathematical vectors, not audio recordings. You can delete any voice profile at any time.

Account Information

If you sign in with Google, we store your email address and authentication tokens via Supabase for account management and subscription tracking. No audio or transcript data is sent to Supabase.

What We Never Do

  • Upload audio to any server
  • Store audio beyond the current day
  • Share transcripts, summaries, or voice data with third parties
  • Use your data for training AI models
  • Sell any user data

LLM Summarization

When you use Claude, OpenAI, or another LLM for meeting summaries, only transcript text is sent to the provider using your own API key. Audio is never sent. You can also use a fully local model via MLX, in which case nothing ever leaves your Mac. FiftyX does not proxy your API requests — your client communicates directly with the LLM provider.

macOS Permissions

FiftyX requests the following macOS permissions:

  • Microphone — to capture your voice and in-person participants
  • Screen & System Audio Recording — to capture audio from Zoom, Teams, and other apps via ScreenCaptureKit
  • Calendar — to detect scheduled meetings and match voices to attendees
  • Network — for authentication and LLM API calls (only when using cloud providers)

Your Controls

  • Pause recording instantly with Cmd+Shift+P
  • Delete the last 5 minutes retroactively
  • Exclude specific apps from recording (Signal, WhatsApp, etc.)
  • Restrict recording to work hours only
  • View the transparency dashboard to see exactly what's stored
  • Delete all data at any time from Settings
