I have created a small application/tool, and I would like to release it to the public under those conditions:
- It is free. (donations are welcome)
- It is closed source.
- In the future, I might create a different version with extra options and charge a small fee for it. (this might not be relevant to this question, just adding all information)
The closest I found was this: https://creativecommons.org/licenses/by-nc-nd/3.0/ - Which is perfect for what I want, but it is not recommended to be used in applications or source code.
How should I license my software ?
