maybe

In your FAQ's you state "Does StartIsBack "phone home"? No..." yet now you have "Desktop toast is shown when new version is available". You can't have it both ways. If you are going to have the software connect to the internet on it's own ("Phone Home") you should make that clear to everyone (both current and prospective users) right up front. IMHOP the best way would be to make "automatically check for updates" an opt-in only choice for the user, like most other user-friendly software.
