I was looking at FitBit but am really not interested in uploading any data. Is it possible to use the FitBit desktop app without permitting it to upload? Would it cache everything locally and function normally or does it require access to be usable at all?
"The Tracker will upload your data every 15 minutes provided you are within range of any plugged in base station (about 15 feet for direct line of sight), the computer is on and not in sleep or hibernate mode, the software is installed and running, and you have an active internet connection."
This implies to me that the data isn't cached locally outside of the Tracker itself, if an internet connection is not available.
