Syncthing is a continuous file synchronization program. It synchronizes files between two or more computers. We strive to fulfill the goals below. The goals are listed in order of importance, the most important ones first.
Syncthing should be:
Safe From Data Loss
Protecting the user's data is paramount. We take every reasonable precaution to avoid corrupting the user's files.
Secure Against Attackers
Again, protecting the user's data is paramount. Regardless of our other goals, we must never allow the user's data to be susceptible to eavesdropping or modification by unauthorized parties.
Easy to Use
Syncthing should be approachable, understandable, and inclusive.
Automatic
User interaction should be required only when absolutely necessary.
Universally Available
Syncthing should run on every common computer. We are mindful that the latest technology is not always available to every individual.
For Individuals
Syncthing is primarily about empowering the individual user with safe, secure, and easy to use file synchronization.
Everything Else
There are many things we care about that don't make it on to the list. It is fine to optimize for these values, as long as they are not in conflict with the stated goals above.
