No. You host them on your server, web site or network, or you can send them by email just like any other file. We never host your unprotected files or your protected files. You always remain totally in control of them at all times.
What we host is the administration system (licensing system) through which you issue your customers with licenses and control who can access your protected documents/products and publications. You can host the administration system on your own server if you prefer.
