The Skydeck Sync Client is a very simple application that runs in the background on your phone and relays your call logs and text messages over a secure connection to your account at Skydeck.com. You never have to look at the Skydeck Sync Client unless you want to change your sync preferences.
The Skydeck Sync Client only works on certain kinds of cell phones(supported phones). If you do not have a supported phone, Skydeck works by logging in to your cell phone company account to fetch your data.
