All our Joomla extensions are Free Open Source Software. In this context, "free" refers to the freedom to copy and re-use the software, and not to the price of the software. Basically, you are allowed to use it in any way you like, for as long as you like, on as many systems as you like.
We use the GNU General Public License v3 , which gives you legal permission to copy, distribute and/or modify the software. Any developers who try to restrict these freedoms are not complying with the GPL and cannot advertise their extensions on the Joomla Extensions Directory.
The only thing we ask of you is that you do not make our paid works publicly available. That would severely reduce our ability to sell them, which would destroy our incentive to continue to develop and support them. So far, this arrangement appears to be generally understood and respected for Free Open Source Software.
We are allowed to apply copyright to our documentation and to restrict your rights to copy, duplicate, or redistribute it. Please respect the copyright of our documentation.
