Private information

Hello, i have a question regarding private information.
If i want to have a social media network using buddy press where there will be a lot of people. So would it be a good idea to use buddypress for this issue?
The thing is a problem of information, how can users make sure that their data will be private as they register on the website, is there a way to guarantee their private information that they share on the website not to be leaked outside the website?
