The privacy label says it all.

Data Not Collected Apple App Privacy

That is Apple’s privacy nutrition label. Developers self-certify their label, and Lucy’s declaration is “Data Not Collected” — because the app has no analytics, no servers, and no way to collect anything.

  • Audio stays on your device
  • Transcripts stay on your device
  • No analytics. No crash reporters. No tracking.
  • No account required — ever.
  • Turn on Airplane Mode — Lucy still works. Transcription runs entirely on-device. There is nowhere for your data to go.

Record. Transcribe. Review.

The whole pipeline runs on your device, offline.

  1. 1
    Record

    Tap Record. A live draft appears as you speak. Lock your screen or switch apps — recording keeps going.

  2. 2
    Transcribe

    Tap Stop. Whisper runs an accurate offline pass. Speaker attribution identifies up to 4 voices automatically.

  3. 3
    Review & export

    Tap-to-edit any word. Export to plain text, Markdown, or PDF with speaker labels and timestamps.

What ships in v1.0

AI-generated summaries, action items, and structured notes are coming in a future update. v1.0 ships transcription, diarization, and export.

Built for professionals who can’t use the cloud.

Mental health practitioners

Document sessions privately. Therapist mode improves transcription of clinical vocabulary. Because Lucy processes everything on-device and we never receive your audio, no BAA is required for Lucy — confirm your practice’s own compliance obligations.

Lock a session and the transcript and audio are encrypted at rest, tied to Face ID or Touch ID. No recovery path — only you can unlock it.

Therapist mode — free vocabulary mode, no extra purchase.

Legal professionals

Record depositions, client meetings, and case discussions. Legal mode improves transcription of legal vocabulary.

Lock a session and the transcript and audio are encrypted at rest, tied to Face ID or Touch ID. No recovery path — only you can unlock it.

Legal mode — free vocabulary mode, no extra purchase.

Anyone who can’t use the cloud

M&A calls, board discussions, sensitive interviews, HR meetings. If the recording can’t leave the room, Lucy is the right tool.

Honest about what works best.

Best results with:

  • Quiet or low-background-noise environment
  • 2–4 speakers with distinct voices
  • One language per recording
  • Phone within 3 feet of speakers

Transcripts may require correction for heavy accents, technical vocabulary, and overlapping speech. Use the inline editor to refine before exporting.

Pay once. No subscription. Ever.
