Licensing and Purchasing Guide

• Our Aim: The license agreements are intended to be fair to both our customers and the team that made the products. Hence, they safeguard the interest of all stakeholders while keeping the terms simple and straightforward.
• Our Considerations:
  • Broad range of applications our customers make.
  • Nature of our components - domain-specific and providing functionality of full-fledged applications
• Our License Types:
  • Trial License
  • Developer Subscription
  • Special Application License
  • SDK License
  • OEM License
  • Student Academic License
  • Source Code License
  • Thought Leader/Technical Evangelist License
• Choosing Your License:
  • For Development: Get one DEVELOPER SUBSCRIPTION for each developer. With one DEVELOPER SUBSCRIPTION, a developer can install the GNOSTICE PRODUCT in one desktop and one laptop that the developer uses. For installing on additional computers, buy additional DEVELOPER SUBSCRIPTIONS.
  • For Distribution:
    • If the software that you are creating is an independent application where GNOSTICE PRODUCT is providing supplementary functionality (say an end-user desktop/server/Web application such as ERP, CRM, DMS, accounting application…), you do not need to pay additional royalty. Your purchase of DEVELOPER SUBSCRIPTION(S) is enough.
    • If the software that you are creating is heavily dependent on the GNOSTICE PRODUCT (such as end-user desktop/server/Web-based document viewers, editors, and converters…), get a SPECIAL APPLICATION LICENSE in addition to your DEVELOPER SUBSCRIPTION(S).
    • If the software that you are creating is a developer tool and exposes functionality provided by the GNOSTICE PRODUCT using an application programming interface (API) (say a component library or a Web API), then get an SDK LICENSE in addition to your DEVELOPER SUBSCRIPTION(S).
    • If the software that you are creating is a developer tool (say an IDE) AND bundles the GNOSTICE PRODUCT in a non-compiled form, then get an OEM LICENSE in addition to your DEVELOPER SUBSCRIPTION(S).
    • If you are a student and want to use the GNOSTICE PRODUCT for your project work, then you can get the low-priced STUDENT ACADEMIC LICENSE instead of the more expensive DEVELOPER SUBSCRIPTION.
• Non-Profit Organizations: Giving discounts for non-profit organizations requires us to be judgemental about their intentions and practices. For this reason, we provide discounts only to students. It requires limited scrutiny and involves no discrimination. This is a convenient policy and we would like to stick with it. Please excuse us if you are a non-profit looking for a discount. We will not be able to help you in that regard.
• License Enforcement Techniques: When installing the GNOSTICE PRODUCT, the installation program may require an Internet connection.
• Assigning an automated build computer: With your first DEVELOPER SUBSCRIPTION, you get to designate one computer as a BUILD MACHINE. For your second BUILD MACHINE, you need to have procured at least 6 DEVELOPER SUBSCRIPTIONS. For your third free BUILD MACHINE, you should have procured at least 11 SUBSCRIPTION licenses. For every five DEVELOPER SUBSCRIPTIONS that you have purchased after your first DEVELOPER SUBSCRIPTION, you can designate only one BUILD MACHINE for free. This restriction is applicable only to computers designated as BUILD MACHINES for free. It does not affect your right to create builds on any computer for which you have procured a DEVELOPER SUBSCRIPTION.
• Renewal, Upgrade and Support Policy:
  • Get discounts on volume purchases
  • Pay only 40% of prevailing price to renew the subscription
  • Upgrade to parent-product bouquets without losing money - pay only the difference
  • Free major and minor updates for 12 months
  • Free e-mail support for 12 months
