KLone is no longer dual-licensed (since version 3.1.0), and has now adopted an extremely permissive Simplified BSD license, which allows commercial KLone-based applications to be built at no cost and royalty-free.

The only obligation involves reproducing the included copyright notice (LICENSE file) within source and binary redistributions. Here it is for reference:
