• 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.
  • Developer licenses are available at discounted prices for purchase quantities greater than 4. Larger teams are recommended to buy the 5-Developer, 10-Developer and 25-Developer Subscription Licenses.
  • For Distribution:
    • To develop/test/deploy/distribute most kinds of software applications using this product, you need a DEVELOPER SUBSCRIPTION, one for each developer or additional computer. No additional royalty would be required.
    • 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). You need to mail us describing your product.

    • 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. You need to mail us describing your product to purchase an SDK or OEM LICENSE.
• 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 and educational institutions. 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.
