The Software

KrySA is released under the GNU General Public License (GPL, or “free software”).

This license grants people a number of freedoms:

  • You are free to use KrySA, for any purpose
  • You are free to distribute KrySA
  • You can study how KrySA works and change it
  • You can distribute changed versions of KrySA

The GPL strictly aims at protecting these freedoms, requiring everyone to share their modifications when they also share the software in public. That aspect is commonly referred to as Copyleft.

License details

The developed KrySA source code is by default licensed as GNU GPL Version 3.

KrySA also uses some modules/libraries from other projects. For example Python uses the Python License, Kivy uses the MIT License, SciPy and NumPy use the 3-clause BSD License, and MatPlotLib uses a license based on Python License.

All the components that together make KrySA are compatible under the GNU GPL Version 3. That is also the license to use for any distribution of KrySA binaries.

Your output

What you create with KrySA (e.g. Data file or Results) is your sole property. All your other output, meaning images/graphs, tables, etc. including the .krysa files and other data files Krysa can write, is free for you to use as you like.

That means the application can be used commercially by anyone to work on commercial projects, research, or for educational purposes.

KrySA’s GNU GPL license guarantees you this freedom. Nobody is ever permitted to take it away, in contrast to trial or “educational” versions of commercial software that will forbid your work in commercial situations.
