The "Share" functionality takes a screen shot and has to save it somewhere. That is the reason for that permission request. If you revoke that permission, the game will still work but you'll have to take the screen shots yourself if ever you want to share your score.

The totals are picked from the numbers that are given to you to use. There is no possibility of a total that cannot be reached by the numbers provided. But I'll check to see if I have some sort of bug in the code.

edit: I've added a notice to the store listing so there's no confusion.
