The way I read that question was: where can other people see this information about me once I’ve published the app? i.e. say I just published an app, where would you navigate to find this info?
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.
