The commercial products evaluation license term is 10 days which can be extended by Qt Sales. During the initial 10 days period Qt Sales will reach out to you to check if you need additional help or a longer evaluation period.
Evaluation enables all Qt product features but may have limited access to maintenance releases. During the evaluation period, you can use the product to the full, but you are not allowed to use it for production or actual product development purposes.
After the free evaluation period, you need to a) either purchase a license or b) uninstall and cease from using the product.
