Attune privacy policy

Last updated 15 October 2026. Applies to Attune for Mac and Attune for iPhone.

The short version

Attune has no servers and collects nothing about you. Your recordings, transcripts, notes and voice library are stored on your own devices. Data only leaves your devices when you use a cloud service you chose yourself — and never for confidential meetings.

What Attune stores, and where

• On your Mac (in ~/Library/Application Support/Attune/): recordings, transcripts, minutes and other outputs, voice notes, the meeting library, your settings, and the voice library (voiceprints).
• On your iPhone: recordings until your Mac has received them, and the summaries your Mac sends back.
• In your iCloud (iPhone app only): recordings travel from your iPhone to your Mac through your own iCloud Drive, in a private app folder. The Mac removes the audio from iCloud once it has it. Cranky Walrus has no access to your iCloud.

What leaves your devices

Only what the services you select need, sent directly from your Mac to that service:

• Transcription with OpenAI (if you choose it): the meeting audio is sent to OpenAI. With Whisper or Apple's engine, transcription happens on your Mac and no audio is sent.
• AI features (minutes, topics, Ask AI, voice note summaries and drafts): the transcript or note text is sent to the AI provider you selected (Anthropic, OpenAI, or your Claude or ChatGPT subscription). With the built-in model, this happens on your Mac.
• Confidential meetings: nothing is sent anywhere.

Voiceprints (biometric data) are never sent to any service. How those providers handle data is described in their own privacy policies.

What Cranky Walrus collects

Nothing. Attune contains no analytics, no tracking and no crash reporting, and it does not contact any Cranky Walrus server. Token usage shown in Attune is counted on your Mac and stays there.

Recording other people

You are responsible for telling participants that you record, and for following the law and your organisation's policies where you and they are.

Deleting your data

Delete meetings and notes in Attune (they go to the macOS Bin), reset voice profiles in Speakers, or remove the folder above to delete everything. Deleting the iPhone app removes its local data.
