Privacy and Security

faq
PirateBox is designed to be private and secure. No logins are required and no user data is logged. Users remain anonymous – the system is purposely not connected to the Internet in order to subvert tracking and preserve user privacy.

will you all help me understand how the piratebox is private and secure beyond no logs are kept and no user data is logged. Are there networking protocols that help with this? I know that clients are isolated by default, are there more precautions like this that are not mentioned?

I need help identifying the the technical specs that make the piratebox secure and private. I can research from there!
