Frequently asked questions

I bought a topic pack but it is still locked

Open Topics and choose Restore purchases (Android), or restart the app. Purchases are tied to the store account that bought them. If it still fails, email us with the order ID (never payment details).

How do I delete my account and data?

See the account deletion guide. You can also request deletion by email if you cannot access the app.

Where do ads appear?

The app shows an interstitial ad after a few draws. Buying a pack removes ads. See the privacy policy for how advertising data is handled.

I want to change the language

Go to Settings → Language and pick Follow device, Vietnamese, or English.
