Onyx: Local AI Notes · Updated 2026-11-07
The short version: Onyx collects no data. The AI that formats and files your notes runs on your device. Your notes live on your devices, and in your own iCloud if you turn on sync. Onyx has no servers, no accounts, no ads and no tracking.
Data we collect
None. Agentic Quarks never receives your notes, recordings, photos, folders, searches or how you use the app. Onyx has no servers of its own, no third-party SDKs, no analytics and no advertising identifiers. In App Store terms: Data Not Collected. You can check this yourself in Settings > Privacy & Security > App Privacy Report.
On-device AI
Formatting, filing, editing with Ask Onyx and search use Apple Intelligence's on-device model on your iPhone or iPad. Onyx does not use ChatGPT or any other cloud AI service, and your notes are never sent to one.
Voice, camera and photos
Voice notes are transcribed with on-device speech recognition; audio is never uploaded. Scans and photos you add are read with on-device text recognition and stay in your notes. Onyx only uses the microphone, camera and photos when you choose to.
iCloud sync (optional)
If you turn on iCloud sync, your notes are stored in your own private iCloud database so they appear on your other devices. That data is held by Apple under your Apple Account and Apple's privacy policy; we cannot see it. With Apple's Advanced Data Protection turned on, it is end-to-end encrypted.
Sharing and Siri
Notes only leave the app when you share or export them yourself. Siri and Shortcuts actions run through Apple's on-device App Intents.
Purchases and feedback
Onyx Pro is a one-time purchase handled by Apple; we receive no payment details. If you choose Send Feedback, your mail app opens a message with the app version, build and system version filled in, and nothing is sent unless you send it.
Children and changes
The app collects nothing from anyone, children included. If a future version ever changes any of this, this page will say so before that version ships.
