I want to set up this plugin for my clients to use for document storage. It looks like a great option. However, when I go to install it, I get a message indicating that my files will be stored on Top Shelf's server. I don't like the idea of my client's critical business information being passed across vendor servers. If I use this plugin, is it true that the files will be stored on top shelf's server (in addition to the S3 bucket that I set up)?
Thank you,
Kevin
