Does You2box use my local internet connection for uploading?

No. You2box uploads your video files straight from Dropbox to YouTube without using your local connection. It tries to use the fastest, most direct available path between Dropbox and YouTube. Thus, none of your precious internet badwidth is consumed, once your video has been uploaded to your Dropbox account.

This makes You2box a valuable tool in situations where your internet connection is slow or unreliable. Dropbox makes sure to reliably upload your files in the background. You2box then moves your videos over to YouTube as fast as possible.
