Hyang is a free software and all Hyang releases are open source distributed under the terms of the MIT License copied below. The spirit of Hyang distribution is liberal that permits reuse within proprietary software, and also compatible with many copyleft software licenses, such as the GNU General Public License (GPL) so Hyang can be integrated into proprietary software as well as GPL software. Hyang may be used for any commercial or non-commercial purposes at absolutely no cost without having to ask us. The only requirement is that if you do use Hyang, then you should give Hyang credit by including the appropriate copyright notice somewhere in your product or its documentation. The Hyang language is entirely maintained by Hyang Language Foundation that keeps Hyang copyright.
In developing the Hyang 1.2.1 (including
hyang.org website and Hyang docs on the Hyang latest release condition), we use external resources including softwares, website tools, and documents which are very helpful for running the project. The list of all external resources and their licenses are shown below.
