Syncthing is a free, open-source peer-to-peer file synchronization application available for Windows, Mac, Linux, Android, Solaris, Darwin, and BSD. It can sync files between devices on a local network, or between remote devices over the Internet. Data security and data safety are built into the design of the software.
Syncthing is an application which doesn’t want anything from the user. It doesn’t put ads into your face, it doesn’t want money from you or your data. It provides a tool with which you can share files in a trade-free manner. However, because of the fact that the website uses cloudflare which collects data (https://www.directory.trade-free.org/wp-content/uploads/2020/11/Pasted-11.jpg) I give 4 out of 5 blocks.
