Why do I need to grant the In-app Purchases permission to CCleaner Android?

In addition to the free version of CCleaner Android, we also offer paid CCleaner Android Pro which includes a range of additional features and functions. The In-app Purchases permission enables you to upgrade to the paid version of the app if and when you want to. You are not charged by CCleaner Android unless you proceed to the purchase screen and provide all of your payment details.
