Please send bug reports and questions by email.
It helps if you include your iPhone model, iOS version, the App's version, and what happened. The App is made by an independent developer, so replies may take some time.
Where is my data stored?
Only on your iPhone. It is never sent to the Developer or to any outside server.
How do I move my data to a new iPhone?
On your old iPhone, use "Export" in Settings to save a JSON file. Then use "Import" in Settings on your new iPhone.
What happens to my data if I delete the App?
It is removed from your device. Always make a backup with Export before deleting the App.
I bought "Remove Ads" but still see ads.
Tap "Restore Purchase" in Settings. You need to be signed in to the App Store with the Apple Account you used for the purchase.
I would like a refund.
Payments are handled by Apple, so please request a refund from Apple.
Cover art cannot be found.
Try "Find Art" again with a different spelling of the title or artist. Turning on "Fuzzy Search" in Settings makes it easier to find matches. If nothing is found, you can choose a picture with "Choose Image".
How do I change the language?
The App appears in Japanese or English, following your iPhone's language setting.
