Dang. You’re right that Mojeek is UK, so Europe but not EU (at the moment, at least). I’ll need to add a remark for that. We already do it for Serper.
Regarding the servers, our servers and data are in the EU. We can’t guarantee that for our providers, but they don’t access your data.
As for Try in/Try with, good point, we can add a preference for swapping them.
