Decked Drafter
Q: I just reinstalled my app. Do I need to repurchase all my existing sets?A: You absolutely do not need to repurchase your sets. The sets are "non-replenishable" in-app purchases, to use Apple's lingo. Apple keeps a transaction history of all your purchases, which means that you will not be charged again if you repurchase them from the in-app store. Alternatively, you can select the Restore Purchases function on the Settings page to restore all your purchases from Apple's servers.
