Distributing PKG outside of appstore

When I gave my installer to my colleague I had to add their uuid code into my developer account.

but surely, if I put my pkg on my website I can’t expect anyone who downloads it to give me their uuid.

I want to u deerstalker d this right. Under what scenario do I need a uuid some someone for them to run my app?

And if I put my signed, notarised app on my website is it going to work as is without giving me uuid?

Thanks.
