Social networks store all our data and shape the way we interact each other. A real network does not need someone to check what you send before giving it to your friend. Newebe is the opposite: it is a real network, and it looks like a real spider web. People directly talk to each other without barriers, spies, or censorship. This means that data you share are directly sent to your contacts and that you host all your data yourself. Because Newebe is set up on a server you host at your home (a very small computer with no screen), everything you make with Newebe is kept inside it and not sent to a third party.
