Nothing is collected.
Here is why that is a fact.

The short version

• Halo has no network code. It cannot send data anywhere.
• There is no account, no sign-up and no login.
• There is no analytics, no crash reporting and no advertising.
• Your audio, transcripts, summaries and mind maps never leave your iPhone.
• We could not identify you if we wanted to. We hold nothing about you.

Why this is verifiable, not just stated

Most apps promise privacy in a document like this one. In Halo it is enforced mechanically: an automated check runs on every build and fails it if any networking symbol appears anywhere in the app. The app ships with zero third-party SDKs of any kind, so there is no analytics library, no advertising library and no crash reporter that could collect anything on its own. The Settings screen inside the app states the same thing and shows a network call count of zero.

What stays on your iPhone

Recordings, transcripts, summaries, action items and mind maps are written to Halo's own storage on the device. Both that storage and the recordings folder are excluded from iCloud and from device backups, so this material does not travel to another machine even when you back your iPhone up. If you delete the app, it goes with it. Export anything you want to keep before switching phones.

Transcription and summaries

Speech recognition and note generation both run on your iPhone, using Apple's on-device speech and Apple Intelligence models. Nothing is uploaded for processing. When one of those engines is unavailable, Halo says so by name and does less; it never silently sends your audio somewhere else instead.

Two things that go through Apple

iOS downloads the on-device speech model once, from Apple, the first time a language is used. Purchases run through the App Store. Both are Apple's own systems and neither is initiated by code inside Halo.

Permissions

Halo asks for one permission: the microphone, and only so it can record when you ask it to. It does not ask for contacts, calendar, location, photos or Bluetooth, and it does not require any of them to work. If you choose to send action items to Reminders, iOS asks for that separately, and only then.

Purchases

Halo is a one-time purchase with no subscription. Payment is handled entirely by Apple through the App Store. We never see your payment details. Apple tells the app only whether a purchase exists on your Apple Account.

Children

Halo collects no personal information from anyone, of any age.

Changes

If this policy ever changes, the date at the top changes with it. Any change that would involve collecting data would require adding network code to an app whose build fails when network code is present, so it would be a different product rather than an update to this one.
