 PM Logo is distributed as a freeware (as in “cost-free”) unique, copyright and trademark protected, software application, written in the Java coding language, enabling implementation across the MS Windows PC, Apple Macintosh and Linux operating systems that are Java enabled. PM Logo may be freely downloaded from the vendor’s website to determine suitability for intended use.

You agree that, as proprietary freeware software, PM Logo must not be modified, its code must not be used for derivative works, nor may it be reverse engineered.

You agree that the PM Logo software application that students routinely use in actively processing their lessons is provided free of monetary charge, and that PM Logo must not be:

  • sold or traded for anything with assumed monetary value;
