New to PR4100, seems like all my data is visible to

Just got my PR4100, upon setup I am finding out that the device is wholly controlled by and monitored by :

Even to move files from one folder to another I need to be logged onto mycloud., which means WD’s MyCloud server has total access to my device at home.

Is there any way to eliminate this dependency and manage our PR4100 without corporate intervention from ?

I don’t want use WD’s MyCloud as a file explorer to manage my files and folders. Any ideas and thoughts.
