@chip-valecek Yes it stays in the binary part of the image - although you can check boxes to ignore this info if you want to remove certain data (in preferences menu).
The XMP (Extensible Metadata Platform) profile it's called in adobe. So you can embed info across multiple projects.
If you are doing quick exports make sure you have the copyright box checked in preferences

There is also a menu called IPTC extension where you can name the artwork, creator, SKU inventory numbers and any models you may have used.
Also add a copyright notice.

I use a program called photo mechanic for doing batch metadata. Where you can store templates so you can copy and paste, if you have a lot of images to label at once. It's reasonably priced too ($150).
It's similar to adobe bridge but exceptionally faster and more intuitive. Built for editorial photographers banging out photos quickly.
