NAME

kasykpolicy - Kasyk Licensing Policy

DESCRIPTION

This is our licensing policy in brief: Our software is 100% GPL, and if yours is also 100% GPL (or OSI compliant), then you never have to pay us for the licences. In all other instances, you are better served by our commercial licence. Read the details below!

Licensing

The Kasyk software is licensed under the GPL license. The formal terms of the GPL license can be found in the file "GNUGPL".

The Kasyk software is also available under commercial non-GPL license. For pricing and ordering information, see our online store at http://www.kasyk.com .

Free use for those who are 100% GPL

If your application is licensed under GPL or compatible OSI license approved by Dijkmat BV, you are free and welcome to ship any GPL software of Dijkmat BV with your application. By "application" we mean any type of software application, system, tool or utility. For doing this, you do not need a separate signed agreement with Dijkmat BV, because the GPL text is sufficient. But we do recommend you to be in touch with us as there usually are good opportunities for partnership and co-marketing.

Free use for those who never copy, modify or distribute

As long as you never distribute (internally or externally) the Kasyk software in any way, you are free to use it for powering your application, irrespective of whether your application is under GPL or other OSI approved license or not.

More specifically.

Modifying - You are allowed to modify the Kasyk software source code any way you like. If you distribute the modified version, all changes, all interface code and all code that connects directly or indirectly to the interface code fall under GPL.

Copying - You are allowed to copy Kasyk binaries and source code, but when you do so, the copies will fall under the GPL license.

Commercial use for everyone else

If your application is not licensed under GPL or compatible OSI license approved by Dijkmat BV and you intend to distribute the Kasyk software (be that internally or externally), you must first obtain a commercial license to the Kasyk software in question.

More specifically:

a
If you include any program of the Kasyk software in your non Open Source application, you need a commercial licence.
b
If you use the Kasyk software within your organization and you don't want to risk it falling under the GPL license, you are welcome to purchase a commercial license.
c
Many users opt for the commercial licence simply because under it Dijkmat BV takes responsibility for its products. Under the GPL licence, there are no warranties or representations from the developer (i.e. from Dijkmat BV).

Exceptions and free commercial licences

If you represent a non-profit organization or an academic institution, we recommend you to put your own application under GPL. Thereby you are free to use the Kasyk software free of charge under the GPL licence. (We also believe that if you have strong reasons not to go GPL, you also have the monetary means to purchase commercial licences.)

If you are a private individual you are free to use the Kasyk software for your personal applications, as long as you do not distribute them.

Please note that even if you ship a free demo version of your own application, the above rules apply.

Finally, what is the recommendation?

To all commercial organizations we do recommend the commercial licence. Not only does this free you from the far-reaching requirements of the GPL licence, it also gives you a licence letter from Dijkmat BV where we assume responsibility for our product. The GPL licence is an "as is" licence with no warranties whatsoever.

To all GPL/Open Source enthusiasts we do recommend our products under the GPL licence. We at Dijkmat believe in the GPL license and all business models derived from using this license. So help yourself to the Kasyk software and feel the freedom of free software!

To anyone in doubt, we recommend the commercial licence. It is never wrong. Thanks to our cost-effective way of producing software, we are able to sell our commercial licences at prices well under the industry average, and this is without compromising our own profitability.

Kasyk Licenses

For circumstances under which a commercial non-GPL Kasyk software license is required, you need a license per physical server. There are no restrictions on the number of connections, number of CPUs, memory or disks to the use of Kasyk software on that physical server.
