You do not get a licence key for CCleaner Android when you purchase it through Google Play Store.

Instead of needing a key your Play Store purchase of CCleaner for Android is linked to the Google account that you were logged into when making the purchase.

That means that your licence for CCleaner Android will be active on any Android device that has CCleaner on it and is logged into that google account.
