Paying $9.99 (USD) once unlocks all topics and full 20-question rounds for the account you used to pay, for as long as the app is offered. There is no subscription, and you will not be charged again. New accounts get a short free trial first.
Payments are processed by Stripe under Stripe’s terms and privacy policy. We never see your card number.
If something isn’t right, email happymoodon@pm.me within 48 hours of purchase with the email you paid with, and we will help or refund you.
Keep your password private. One purchase covers one account; family members can share it on the same device. If you delete your account, the unlock is removed and can’t be restored.
Please don’t try to break, copy or resell the app or get around the paywall.
The quizzes are for fun and learning. We try to keep answers accurate but can’t promise every one is perfect, and the app is provided “as is”.
We may update these terms; the date above will change when we do.
