Magic Wormhole: get things from one computer to another, safely

I have a list of now 22 browser based p2p sharing tools that i shared here a few times in similar threads https://gist.github.com/SMUsamaShah/fd6e275e44009b72f64d0570...

I find myself using Send Anywhere [1] all the time. I couldn't find documentation on how the files are transferred or if they're uploaded to their cloud, but it's very handy. They claim the files are encrypted in transmission, but don't give details & could just be talking about SSL.[2]

When you choose the files you want to transfer, it gives you a 6 digit code or a QR code. Once you enter that, the files are transferred! It's available for most all major platforms, but isn't open source. [3]

I haven't read their privacy policy. Frankly, I'd rather not know...
