If you sign an app your legal name gets embedded into the .app bundle. You can use e.g. `codesign` in the terminal to read it back, or if you publish to the App Store it will be in the UI, along with the others.

I've seen individual developer's names in the App Store, but the parent comment is also claiming that Address and Phone number is published. I've done a bit of digging, and can't seem to confirm this.

In Europe’s App Store I see my address and phone number in the apps I published there - under the “provider” section.

Interesting. Looks like this is EU specific.
