I downloaded a channel called "Albany News and Weather". As far as I can tell it's not affiliated with any local tv station or network and it never identifies itself anywhere or at anytime that I've watched it. I googled it's name and came up with nothing. How can I find out who's running this thing?
Go to Roku channel store in a web browser. In your case, the developer is ZMG.

I typically start by clicking on the Privacy policy link in the channel store. In this case that takes you to some rather generic getterms website, but that privacy page does have a link to ZMG Ruckus factory. That website also seems fairly generic but does have a contact form at the bottom of the “Our Story” page.
