Bingoku is made by one person. Email is the way to reach me.

Please say which phone you use and what version of the app you have (Settings, at the bottom). If something went wrong with a purchase, include the order number from your Google Play receipt.

Questions people ask

My sparks or progress are gone after changing phone.

Sparks, unlocked books and purchases are backed up to your account, but only if you were signed in with Google. Install Bingoku on the new phone and sign in with the same Google account from Settings. A guest account is tied to one install and can't be moved.

I bought something and it hasn't arrived.

Open the shop and tap Restore purchases, or Settings and Already paid? Restore it. Purchases are handled by Google Play, so check the receipt in your email or in Play Store under Payments and subscriptions. If it still hasn't arrived, email me with the order number and I will sort it out.

How do I remove the adverts?

There is a one-time purchase for that in the shop and in Settings. It also turns off the video option for hints on practice cards, since there is no video left to watch.

When does the next card appear?

Every day at midnight UTC, the same moment for everyone. The countdown on the home screen shows how long is left.

Can I delete my account and my data?

Yes. See how to delete your account and data.

I found a card that looks wrong.

Please tell me. Send the card number and date from the top of the card, and what you saw.
