What is the best way to store information about the game coins purchased by the user?

Question

Android

The user can buy a package of game coins through the billing market. I wanted to add them to the current balance stored in SharedPreferences and report their full use to the market, the user can buy again. But if he reinstalls the application, then the information about unused coins will be covered and they will not be restored. Will it be ok? Will there be any complaints?
