"The Personal Edition of HelpNDoc is completely free, without any limitation in time, for personal use (this means for non-profit and non-commercial uses) and evaluation purposes. The only differences between the free Personal Edition of HelpNDoc and the purchased full versions are some advanced features missing, and a discreet banner displayed at the bottom of each page."

Despite the reference to advanced features in the purchased version, MajorGeeks states that the Freeware version is fully functional.
"Fully functional with discreet banners at the bottom of all documents. Prices start at $113.00 and will remove banners and allows commercial usage."
