Small suggestion: your docs could use a little work. The language switching is broken, and the history state is broken, so when you click around the docs, you quickly end up with 20+ entries in your history.

Also, the site could definitely use more copy: how do CSPs work? How does the app work in general? Right now the only real details are in the documentation.

Also also, what information ends up back on your servers? Is any user data relayed through an API?

It's a very cool idea, just non-obvious at first glance what exactly it does :)
