Hallo, wie bekomme ich ccleaner und kamu auf mein Handy?

If you already have a multi-device CCleaner licence, ie. CCleaner Pro Plus or CCleaner Premium, then:

If you don’t already have such a licence then you can either buy one of them, or you can just buy CCleaner for Android directly from Google in the Play Store:

Note that if you buy direct from Google then you do not get a licence key, it is automatically active as long as you are logged into your Google acccount.
