i use win8, iphone and ipad.
You claim that we can't get refund if we buy it on apple store.
But if i buy it from google appy store and install them on iphone and ipad and won't be satisfied, Can I get refund?
A Premium purchase upgrades your account on every device on all platforms so you can pay through our website using a credit card or PayPal for the fastest refund option, you can also use Google PlayStore which also allows us to send you your money back.
Only Apple's store makes it impossible for developers to process refunds.
