GNU General Public License
This license is a one time / purchase commercial license allowing you to use MODX extra or software on as many sites as you want, with some restrictions (please see below).
Updates and evolutions for commercial licenses
The purchase of a license for a specific version does not necessarily give the right to the free acquisition of all subsequent versions
Updates or major changes to a extra / software may give rise to the sale of the updated version as if it were a new extra or software under the same name.
For exemple if you purchase the xAjaxLogin version 1.0.4 extra for MODX, you may need to acquire a new license for version 2.0.0 if version 2.0.0 is a major update with new features.
Itchiweb.com is the only entity that can decide whether a new extra/software version constitutes a major version eligible for sale.
Restriction for all commercial licenses
are strictly prohibited.
