Yuuri (余日) does not collect, upload, or share any user data. All events you create are stored locally on your device only, and we have no access to them.
- All countdown events (title, date, icon, color, reminder time) are stored only on your device using Apple's SwiftData framework for local persistence.
- Your data is never synced to any server or cloud service, including our own.
- Uninstalling the app permanently deletes all your data.
- If you enable a reminder for an event, the app will deliver a local notification at your chosen time.
- Notifications are generated entirely on-device and are never routed through any server.
- You can disable notifications anytime in Settings → Notifications → Yuuri.

This app does not integrate any third-party SDKs, including advertising, analytics, or crash-reporting SDKs.
This app is not directed at children under 13 and does not collect any personal information, so there are no children's privacy concerns.
