Open Dot, go to the You tab, and tap Restore purchases. Make sure you're signed in with the same Apple Account you used to subscribe.

Open the Settings app on your iPhone, tap your name at the top, tap Subscriptions, choose Learn Mahjong with Dot, and tap Cancel Subscription. You keep Dot Pro until the end of the current billing period.

Refunds are handled by Apple. Visit reportaproblem.apple.com, sign in, find the purchase, and choose Request a refund.

No. Dot teaches with original practice patterns written for learning how to read a card. They are not hands from any official card, and Dot is not affiliated with the National Mah Jongg League. Table customs vary, so confirm house rules with your group.
