People are nice? But most likely they want a good relationship with me in case they get problems. Also they benefits from being able to tell their customer they support the project.

Ahh, I see. So you are receiving donations. Royalties to me mean payments that are required not voluntary.

[darthcloud]

I consider donation what random user give me on patreon/gh sponsor/itch.io

I talked with the makers or manufacturer and we reached an agreement. So to me (and them) it's royalties.

[dom96]

What you consider and your manufacturer considers doesn't matter. The definition of royalties is what matters, it doesn't fit in this case as far as I can see. They aren't paying you money so they can use your software, they are donating money because they are nice, they could stop paying at any time and continue to use your software.

They get ad placement for the money paid ie a commercial transaction not donation.
