Onnal (bundle identifier com.ootssu.onnal) is published by Shin Jungsoon. This page describes what data the app does — and does not — collect.

Summary

Onnal does not collect any personal data. Everything you write stays on your device and, optionally, in your own private iCloud account. No data is ever sent to the developer or any third party.

What stays on your device

Your daily one-line diary entries, mood emojis, and weekly recaps, stored locally with Apple's SwiftData framework.
Your reminder time, language, and other preferences, stored in iOS UserDefaults.
Any text you type in the editor (used only in-app for that entry; never sent to any server controlled by us).

iCloud sync (your private database)

Onnal uses Apple's CloudKit to mirror your entries between your own Apple devices via your private iCloud database (iCloud.com.ootssu.onnal). This means:

Data is encrypted in transit and at rest by Apple.
Only you can access it — neither the developer nor any other user can read it.
If you sign out of iCloud or disable iCloud for Onnal in iOS Settings, sync stops and the app continues to work locally.
Deleting the app or signing out removes the local copy; you can also delete the iCloud copy from iOS Settings → Apple ID → iCloud → Manage Storage.

On-device AI (Apple Foundation Models)

On supported devices (iOS 26+), Onnal uses Apple's on-device Foundation Models framework to generate the weekly recap from your local entries. This processing happens entirely on your device. Your entries are never uploaded to Apple, OpenAI, Anthropic, or any other AI provider. On earlier iOS versions, the weekly recap falls back to a simple on-device summary that uses no AI at all.

What we do NOT collect

Your name, email, phone number, address.
Your contacts, photos, calendar, microphone, location, health data.
Any analytics, telemetry, or product usage events.
Crash reports beyond what Apple already provides via App Store Connect (anonymous, system-wide).
Advertising identifiers (IDFA). Onnal does not show ads.

Third-party services and SDKs

None. Onnal contains no third-party analytics, advertising, tracking, attribution, or telemetry SDKs. The only external services the app interacts with are Apple's own — CloudKit (for your private sync) and Foundation Models (on-device). Use of those services is governed by Apple's Privacy Policy.

Cross-promotion

Onnal may display a static card linking to other apps by the same developer. These links go to the App Store; the app does not fetch tracking-enabled metadata for them, and tapping them is fully optional.

Data export and deletion

Export: You can export all your entries as JSON at any time from Settings → Export.
Delete locally: Uninstall the app to remove all on-device data.
Delete from iCloud: iOS Settings → Apple ID → iCloud → Manage Storage → Onnal → Delete Data.

Children

The app contains no objectionable content and does not collect data from children or anyone else.

Data retention

All on-device data persists until you delete the app or clear its data. iCloud data persists until you delete it from iCloud. There is no server-side store operated by the developer to delete from.
