Check out
this page to see what export modules are available for each license. For instance, the Desktop license allows you to export to Windows, Mac and Ubuntu, and the Mobile license allows you to export to Android and iOS. A single paid license would suffice to remove the Trial limitations and will even allow you to test the game on your PC without having to own the Desktop license if you don't want to create games for desktop platforms.
Note than all those licenses are separate and buying the Web license alone won't let you export to Desktop platforms. They are in no way extended versions of each other.
