FAQ

Check these first

In the existing FAQ below, “Stardust” is the legacy term; the current app uses “Stars.”

Stardust · Payments

What is Stardust used for?

Stardust is an in-app point for optional features. You can use it for 1, 3, and 5-card readings and to unlock premium card packs, and every change — top-up, spend, refund — appears in your usage history.

How do refunds work?

Top-ups and refunds follow App Store and Google Play policies. Stardust already spent is generally non-refundable. For billing questions, send your customer UID and receipt screen for a faster check.

I paid but didn't receive Stardust.

Payments are reconciled between store records and our server ledger. If it still isn't reflected, relaunch the app to sync; if the issue remains, contact us with your customer UID and receipt.

Card Packs · Readings

A card pack won't download.

Check your network and retry in the app. Unlock and download status are shown in the app. If it keeps failing, contact us with the card-pack name.

  • The Vintage Cat tarot is free to download.
  • The Ink-wash Cat tarot unlocks with Stardust.
How do I view a reading result?

Enter a question and select cards to receive a reading shaped by orientation and card count. View it in light, dark, or a clean classic style, and revisit saved readings alongside your diary.

The current app has 8 result sheet styles; the styles listed in the existing answer above are examples and only a subset.

Account · Data

Where are my diaries stored?

Diaries and saved readings are kept on your device by default. You can export what you need as Markdown. We cannot view or recover local records that are not stored on our servers.

I want to delete my account.

You can delete it directly via Settings › Login info/Account › Delete account. If you can't use the app, you may request deletion on the web.

I can't sign in.

Try again with the provider you used — Google, Apple, or Kakao. Signing in with a different provider may be treated as a separate account. If it persists, tell us which provider you used and we'll help.
