Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet. Private. None of your data is ever stored anywhere else other than on your computers. There is no central server that might be compromised, legally or illegally. Encrypted. All communication is secured using TLS.
