FAQ

Where is my data stored?

Everything is stored on your device only — no external transmission or collection. No account is required.

I'm not getting expiry notifications.

Check that notifications are allowed for the app in your device Settings, and that "Expiry notifications" is on in the app's settings. Even with notifications off, you can check expiry via the badges on each screen.

Can I keep my purchase after switching devices?

Yes — use "Restore Purchase" in the app with the same Apple ID.

How accurate are the required amounts?

They are general guidance based on Japanese public preparedness materials. The app does not determine whether to evacuate or provide medical advice. For final decisions, check your local government's official information.
