Privacy Policy

iPhone app “Lucky Days” (一粒万倍日)
Effective date: October 15, 2026
Last updated: October 17, 2026

1. Information We Collect

The operator does not collect any personal information through this app. The app has no account registration, and it does not send your settings or usage to the operator’s servers or anywhere else outside your device.

2. Information Stored on Your Device

Your notification settings (on or off, and the day and time of the reminder) are stored only on the device you are using, and the operator does not receive them. Deleting the app also deletes these settings.

3. Notifications and Widgets

Notifications are scheduled and shown on your device. The widget content is also calculated on your device from the date. Neither uses an external server. You can change notification permission at any time in the iPhone Settings app.

4. External Services

This app does not include analytics, advertising or any other external services.

5. Sharing with Third Parties

Because the operator does not collect personal information, it does not share any with third parties.

6. Contact

If you contact us by email, your email address and the content of your message are used only to reply to and handle your inquiry, and are deleted when no longer needed.

7. Changes to This Policy

We may change this policy when needed, for example when the app’s features change. The updated policy applies from the time it is posted on this page.

8. Operator

Operator: Miki Matsumoto
