Privacy Policy
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.
Beta-stage disclosure
FiftyX is in public beta. The product works end-to-end, but you should expect bugs and rough edges. We collect a small amount of anonymous diagnostic data (described below) so we can fix issues we can't reproduce ourselves. If you'd rather not participate, please don't install the beta — there's no in-app opt-out yet.
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, Gemini, or Grok for meeting summaries, only transcript text is sent to the provider using your own API key. Audio is never sent. FiftyX does not proxy your API requests — your client communicates directly with the LLM provider, so the only entity that sees your transcript is the provider you chose.
Diagnostic telemetry · Sentry
FiftyX includes Sentry for crash and error reporting. We do this so we can fix bugs we can't reproduce on our own machines. The Sentry integration is configured to be privacy-safe by construction:
- An anonymous installation UUID is generated locally on first launch and stored in your Mac's UserDefaults. It is not tied to your name, email, account, or device identifier — it only lets us correlate "this user hit bug X three times" without knowing who you are.
- Stack traces, error messages, and breadcrumbs (categorized events like "recording started") are sent.
- No transcript text, audio, voice embeddings, file contents, calendar event details, contact names, email addresses, API keys, or URLs are sent. A scrubbing layer drops anything matching those patterns before it leaves your Mac.
- Network breadcrumbs and user-interaction tracing are disabled.
This will become a user-facing toggle before FiftyX leaves beta.
Auto-updates · Sparkle
FiftyX uses the open-source Sparkle framework to deliver updates. On launch and periodically, FiftyX fetches a public update manifest at https://50x.ing/appcast.xml over HTTPS. The fetch contains a standard User-Agent and your current FiftyX version; it does not include any account, hardware, or content data. New versions are cryptographically signed and verified before installation.
macOS permissions
FiftyX requests the following macOS permissions:
- Microphone — to capture your voice and in-person participants
- System Audio Recording Only — to capture audio from Zoom, Teams, browsers, and other apps via the Core Audio Process Tap (audio-only; no screen capture)
- 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 at any time from the FiftyX menu bar item
- Delete the last five 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
