How to choose a software license for mobile development?

Question

Mobile development

Hello.
I develop applications and games for Android. I'm going to do it for iOS too.
I would like there to be no problems with licenses in the future, since I use various 3d models and sounds that I find on the Internet in applications. Also, I would not like to make the source code open.
Is it enough that I will write where I downloaded other people's things in "about the game"? What should you do to protect yourself?

Answer 1

Usually, in those places where you downloaded the resources, it is written under what license they are distributed. There can be a bunch of options, from "you can bart and use it as you like, without any instructions" to "you can't touch it at all."
See license type and read more about it.

Answer 2

"What should you do to protect yourself?" - it's not really your license. Or maybe not even your license. Your license protects your product from reuse - so that they don't sell without you, so that your art or ideas don't get torn apart.
But in order to "protect yourself" you really need to carefully read the licenses of those blanks that you want to add to your product. Read their licenses.
