I exclusively use my sonos speakers inside my secure home network. I do not need to have remote access. I do not want any of my internal music information to be stored in the cloud/internet irrespectively of the perceived benefits. I just dont need it - when I listen to my music on Sonos I am always home and if I am home I am connected to my local network, I absolutely dont see the reason for play.sonos.com.

Having said that, I cannot find any way to remove my sonos.com account and ensure all the data that is associated with this account is securely deleted. Is this even possible?

Any help would be appreciated.
