Developer-readable data: legal receipt only. No account, no sign-up. HarkNote processes recordings, transcripts, speaker labels, optional Self voice matching, summaries, and Q&A on your iPhone. The only developer-readable app record sent to CTK Advisors LLC is the minimal legal acceptance receipt described below.
Recording, transcription (WhisperKit via Core ML / Apple Neural Engine), speaker identification, and optional Self voice matching run entirely on your iPhone.
Summaries and Q&A also run on-device: Apple's Foundation Models (Apple Intelligence) where supported, otherwise a built-in deterministic text heuristic. No audio or transcript text is sent off-device for processing.
No user content uploads to us. HarkNote may download on-device model assets so transcription and speaker detection can run locally. These requests do not include your audio, transcripts, notes, questions, summaries, calendar content, voice profiles, or speaker embeddings.
App database data, including optional voice profiles and speaker embeddings, may sync via Apple's private CloudKit service when iCloud is available for HarkNote. Audio files use your iCloud Drive container only if you select iCloud storage. We never receive or can read your iCloud data.
When you accept Privacy & Terms, HarkNote sends CTK Advisors LLC a minimal legal acceptance receipt containing document versions, timestamp, app/build, receipt ID, and document hashes. It does not include recording content or personal account information. This is the only developer-readable app record sent to us.
No analytics. No telemetry. No crash uploads. No advertising IDs. No trackers.
Required only to record audio you start. Never accessed otherwise.
Optional, read-only. Links a recording to a meeting. HarkNote never creates, edits, or deletes events.
Both are optional and can be declined or revoked in iOS Settings at any time.
Delete any session in-app — it removes the audio, transcript, and metadata from HarkNote. Uninstalling removes local data from that device. In-app recordings are standard .caf audio files. We keep no server-side copies of your recording content.
Recording-consent laws vary by jurisdiction and you are solely responsible for complying with them — obtaining consent and giving notice where required. See the Privacy Policy for the full notice.
