Do Kutool functions work for others?

I plan on buying Kutools for non-commercial use, but often create excel files for others(also non-commercial), but also 1 or 2 files for work(ofcourse that is somewhat commerceial, albeit to only facilitate some daily actions).

Does a file I create at home with Kutools(example create an e-mailbutton) work when the workfile is opened on a different PC without Lutools installed?
