For all software and plugins where a license is offered, a free version is available for testing.
The only difference between the licensed software and the free is the lack of a nagging dialog, making clear that you are using the software unlicensed.
Therefore, before aqcuiring a license, the buyer can test out all functionality of the offered software, as well check if the software is compatible with the system used.
Therefor no refunds or returns are available for the licenses.
Ending the license before the license period is ended does not grant the buyer a refund.
