The email is mandatory but you can input "[email protected]" - I placed it _before_ deciding i wouldn't make an account mandatory; Good catch, will be removed :)
For now, data sharing is via "export / import" (you can access it on the tools page) - It's not very robust, but I have yet to find a solution that doesn't involve me having a server receiving any kind of data (which is my north-star), I'm still exploring this as I ended up with the same problem as you: only I can control the data and my partner has to rely on me.
I'll send you a ping once I figure out a more robust and equally private way of sharing the data :)
