Hello,
I recognized that you have two different icons for CCleaner Cloud:
The icon of the application in the system tray is a white "C" on blue background.
On the CCleaner Cloud website you use the icon of CCleaner (red "C" with a broom on white background).
In my opinion the same icon should be used for the website and the application.
The icon of an application is a brand, so it should be unique.
Greetings
OLLI
