POLYNOM

Polynom was been created by a team of hackers, game developers, and technologists in order to make a fun, engaging collaboration platform that is founded on cutting-edge, modern, and strong cryptography. It's the convergence of our two worlds - fun collaboration + secure collaboration... With Polynom, it's YOUR SERVER, YOUR DATA, YOUR RULES. Our Polynom Community server makes it easy for anyone to host their own collaboration platform. It is free for individuals and small businesses (SMEs).
