Privacy Policy: Brain Dump

Last updated: October 1, 2026

Lunar Computing, Inc. ("we," "us," or "our") develops the Brain Dump iOS app. This Privacy Policy explains how Brain Dump handles information when you use the app.

Brain Dump records and transcribes on your device. Voice notes never leave your iPhone. If you are signed in to iCloud, transcripts sync through your own private iCloud, which we cannot see.

1. Data stored in the app

Brain Dump is designed around local, on-device storage. Depending on which features you use, the app may store:

  • Voice notes (audio recordings), which stay on this iPhone and are never synced or uploaded
  • Transcripts, tags, park-for-tomorrow flags and timestamps
  • App preferences and Brain Dump Pro status

This data is used to provide app functionality and is not sold, used for advertising, or shared with data brokers.

2. Optional permissions

  • Microphone: Records your dumps. Used only while the record screen is open.
  • Speech recognition: Transcribes your dumps on-device with Apple Speech. Audio is not sent to Apple or to us. If on-device transcription is not available for your language, the voice note is still saved without a transcript.

You can revoke iOS permissions at any time in Settings. Some app features may stop working after a required permission is revoked.

3. iCloud and on-device processing

Transcripts, tags and park-for-tomorrow flags sync through your private iCloud container when iCloud is on. Audio files stay on the device.

Apple controls iCloud account authentication and CloudKit infrastructure. We do not receive your Apple ID password, payment information, or private iCloud account credentials.

4. Purchases

Brain Dump Pro is an auto-renewing subscription processed by Apple and checked with RevenueCat using an anonymous ID. We never receive your Apple ID or payment details.

5. Third-party services

Depending on the features you use, Brain Dump may interact with:

  • Apple Speech framework (on-device transcription)
  • Apple AVFoundation (recording and playback)
  • Apple CloudKit (your private iCloud)
  • Apple in-app purchase
  • RevenueCat (subscription status, anonymous ID)

Third-party services process data according to their own privacy policies. We only use them for app functionality, entitlement verification, system permissions, or user-requested actions.

6. Health, wellbeing, and reference content

Brain Dump is not a medical device and does not provide medical, psychological, legal, financial, or other professional advice. Any journalling, reference, or study content is provided for personal use and self-reflection only. It should not be used to diagnose, treat, prevent, or make decisions about a health condition.

7. Your choices

  • Delete local app data from inside the app where available.
  • Delete the app from your device to remove local app data stored in the app sandbox.
  • Manage iCloud data from iOS Settings if you enabled iCloud sync.
  • Cancel or manage subscriptions in iOS Settings under your Apple ID subscriptions.
  • Revoke optional permissions, such as Microphone, Speech, or Notifications, in iOS Settings.
