Wow, thats one kind of a project. I'm impressed. Though it doesn't really fit my problem. It has to be something webbased, where everyone of us can use it without an app, without seeing each others information. From the github page it looks like a local tool. And also focused trading similar items. The presents in our secret santa are highly individualized, so randomly trading does not make much sense. And if the interface is too clunky, my non-tech siblings will just reject using it. I want to keep them from deciding for some free privacy nightmare app.

But I thank you for the suggestion. Its an interesting project
