That's a great question. Hopefully given you can make a purchase and start using an account without ever providing any personal information, it should help.

My wife has no public information, and as for me, hopefully seeing some of my public interactions mostly related to code forges or here, in lobsters, IRC, or Privacy Guides, there should be enough to get a sense of what I stand for.

Regarding Uruky itself and search, we've published a Threat Models document with some more information that should help clarify everything: https://uruky.com/docs/threat-models

Thanks, I hope that helps!
