have I been pwned?

So I went to the site recommended by the recent dw_news. I found an interesting fact: It claimed one of my email addresses had been compromised. However, the password I've used at that account for years, it claimed had never been seen in any breach. So, whatever data they have, it isn't connected. Maybe it's some site where my username for the site is that email address. Anyway, I'm not really worried. I have very little to hide. I suspect that if someone tried to steal my 401k or something I'd be able to get it back, and they're welcome to my purchase histories.
