Turn off companion automatic starting

This is the most annoying feature ever. I do NOT want pocket cloud companion to automatically start and log me in every time I restart my computer. There are absolutely no preference settings anywhere in the program, and that's more than a bit asinine. At least let me choose to not have it automatically start! Honestly, the lack of such a basic feature is making me dislike the entire product. You guys just invented a pair of jeans with no button or zipper; excellent product, missing basic functionality.
