Evening project, small tool to transfer files between two devices without having to log-in to anything, install anything or stash files online for the world to see. Yes, there will be bugs.
While odds are you are telling the truth that nothing is stored, there is still no way I'd ever trust a rando server on the internet to be a middleman to transfer files between my devices.
Absolutely, neither would I (and yet I use gmail) my intention is to drop this off at github at some point (when I have implemented E2E encryption) and let people host it themselves. It's only a few lines, so it should be rather easy to audit before self-hosting it.
I made it mostly for myself (since I have no problem trusting my own server), but thought the concept was neat enough that I'd share the idea.
