Thank you, Puritans.

It does! And there's no server, it's all sync'd locally or encrypted over the internet. You just need to install it on both devices and point them at each other. I don't believe it works on iphones though. Or at least without jumping through a lot of hoops.

How do you feel about using Syncthing? I use it to sync my notes and files between myself, but it could work in a family setting.

One word of caution, the folder ID (xxxxx-xxxxx) has to be the same for each folder you want to sync.
