I don't understand how my data is safeguarded by my home server when it's data I'm sharing with users who aren't on that same server. Once the data is shared, it's no longer under my control. I've wondered if there is a way to protect it, but I've yet to figure it out.
Of course, I'd love to find that there is someone who has a solution. I was unable to determine if buddycloud has figured it out.
