We believe that with WordPress management solutions that are hosted on the developer’s servers or are self-hosted but contain encrypted code that you can never truly be sure how that information is being used or even what information about your sites is being gathered.
Since MainWP is hosted on your WordPress install and not on our private server, you can be sure we do not track or keep any information about your Child sites because MainWP is open source and not encrypted. You are free to audit the code for yourself at any time via GitHub.
Allowing people to host everything on their server does make coding the plugin quite a bit more difficult for our developers. Still, we feel that the privacy and security of the networks built using MainWP were more important than controlling our servers.
