Why is the software available for free?
CubePDF series sometimes bundles other software with the installer and asks if you want to install them as well. This distribution method is commonly referred to as bundleware. These bundled software bundles directly or indirectly defray the cost of ongoing development and maintenance of the Cube series, and are offered free of charge. With regard to bundling with CubePDF series, we are following the policy of not installing the software by default (opt-in).
Can I use it within my company or for commercial purposes?
Yes, CubePDF series can be used freely by both individuals and corporations. For example, you can use it for your company's business, or use it as a part of the system you sell, etc. You can also use it for commercial purposes.
Are any restrictions on how I can use it?
No, there is no limit to the number of installations of CubePDF Series, and you can use it in any way you want, as long as it is feasible.
However, in principle, you are responsible for your own use. CubeSoft, Inc. provides a support e-mail address, firstname.lastname@example.org, and we will try to respond to you as much as possible. However, some of your inquiries may be related to special conditions, and we may not be able to answer them. In particular, since CubePDF works with a wide variety of applications (through printing) due to its nature, there are many things that we cannot understand.
Can I distribute the software from my company's server?
Yes, you can save the CubePDF series installer on your internal server and redistribute it freely. However, CubePDF series is constantly being updated. If you want to redistribute it elsewhere, please make sure to check for the latest version as regularly as possible.
What is your support policy?
The Cube series will remain supported until explicitly notified of the end of development. However, all vulnerabilities and other functionality fixes will be done in the form of version upgrades. Therefore, as a general rule, only the latest version of each product will be supported.
Is the source code available to the public?
