Does Uploading to MyBook Uses Internet?

Hello all, whne I upload files to MyBook Live the internet usage meter I have shows that I have used my internet bandwidth usage plan. I thought that all of the activity btw the MyBook and other devices I have (iphone, iPads and MacBook) is done under the local wireless network and doesnt count toward internet bandwidth usage. Are there settings where I can see or controls these options? I dotn want to go over my bandwidth limit.

Thanks!

Hi avish_mo, if you use the WD My Cloud app on your local network it will use your local bandwidth to transfer the file.
