GeoGebra License

You are free to copy, distribute and transmit GeoGebra for non-commercial purposes (please see details below).

Guidelines to distinguish Non-commercial and Commercial Use

You may only use the GeoGebra Software and Materials under the terms of a relevant license agreement. The license agreement which applies to you depends on your use of the Software and the Materials, which can be summarised as follows:

Whether a particular use of the GeoGebra Materials is "non-commercial" depends on the use, not the user, and to assist we have set out the notes below:

  1. Non-commercial Use. We anticipate that non-commercial use will primarily involve students and teachers who may wish to use GeoGebra at home and in school or university for the purposes of their school or academic study and teaching, without intending to seek any commercial advantage or financial gain. This includes teachers in schools and universities where tuition fees are charged, so long as the use of GeoGebra is limited to personal or individual classroom teaching. 
  2. Commercial Use. We anticipate that commercial use will primarily involve publishers, online schools, schools or universities charging tuition or course fees where there is systematic or formal integration of GeoGebra within the curriculum, and non-profit organizations who wish to use GeoGebra to support activities that are intended toward securing a commercial advantage or the generation of revenue or monetary compensation.

Examples of commercial use might include:

GeoGebra License FAQ

What exactly is the GeoGebra software?

When we refer to 'GeoGebra' software or as a product, we are really referring to a number of component parts which together form the working GeoGebra software program. The most important of these constituent parts are:

These distinctions are important when considering how GeoGebra is licensed, as these constituent parts are made available under different licenses.

How is GeoGebra licensed?

We license the different component parts of GeoGebra differently depending on their origin (authorship) and depending on your intended use of GeoGebra (see also next question)

Thus, there are really many different licenses involved in the background.

Who can use GeoGebra free of charge?

GeoGebra and our web services are made available free of charge for non-commercial users. Most of our users are students and teachers and they usually fall under our non-commercial license, allowing them to use and distribute GeoGebra and related materials free of charge at home and in school.

Commercial users pay a moderate license fee, which helps us to continually improve GeoGebra and keep it free for non-commercial users. Please see some examples on how we distinguish non-commercial and commercial use. If you are not sure whether your use is commercial or not, please just get in touch with us at ILF.SL2YIFYI@YQGOOF@.

Is GeoGebra free and open source software?

GeoGebra is open source software and available free of charge for non-commercial users. You can find our source code online and we are actively collaborating with the open source community and other open source projects used by GeoGebra. Thanks a lot to all contributors of these projects for their great work!

Please note that GeoGebra as a complete software program would probably not be considered "free" software according to the definition of that term which is used by the Free Software Foundation. This is because the restrictions on commercial use that apply to the GeoGebra installers, web services and language files add-ons might be seen to be a restriction on the software as a whole (thus making it "non-free"), even though the GeoGebra source code is made available under the GNU General Public License without restriction. You can rest assured that our license terms fully respect all existing licenses from third parties (including the GNU General Public License and all Creative Commons variants) and have been checked by an experienced law firm.

Most importantly, GeoGebra will always continue to be available free of charge for students and teachers for all major operating systems. We are also providing installers of our latest versions for the main Linux distributions (these are available to download from the wiki).

The GeoGebra Group is dedicated to the open source movement and collaboration with members of the FOSS community  – please do get in touch if you'd like to help us make GeoGebra even better.
