Well, this question is allegedly buried into thousand lines of EULA that every user of Bitbucket signs during registration, but anyway I'll bother someone for a quick and concise question.
I'd like to set up a remote for a repo strictly copyrighted, and a mate of mine said me that no matter what "private repository" means, Atlassian will always have property of each piece of information I'll upload on their server. Thus, is it virtually possible a situation where this code will be copied, retained or whatever, in facts breaking the copyright that I ought to respect?
