Probably (Mastercard provides free monitoring of leaked databases: https://mastercardus.idprotectiononline.com/enrollment/embed...) however the service is kinda garbage because they censor it so much that I have no idea what of my data is actually leaked), but from a quick Google search it looks like you've voluntarily given out a lot about yourself anyways. I think most people have and are lulled into a sense of false security simply because no one has a need to target them yet. Sort of like the "I've done nothing illegal so I have nothing to fear" mentality but substitute government with criminals.

I often wonder how big my data footprint is. I don't have any social media, and I cycle between a few handles on any publicly facing site I keep an account with. I suppose Google must have all of my search history associated with my main email address, but I use several different emails and browsers in my day to day.

I guess I'm wondering how good all of these companies are at sharing data between themselves. What kind of data is exposed when I use my primary email to log into Zoom or Spotify on a work computer, or my phone, or one of my relative's computers? To what extent do these companies coordinate and share this data?

It all just seems like a really big unknown to me, and I'm relatively tech savvy.
