Three different commercial license types are available for purchase: Development License, Runtime License, and Source Code License. A development license is required after the free trial period has passed. Runtime licenses are required as soon as an application gets deployed into production. There is no difference between in-house deployment or customer-site deployment.

Development License
The development license allows the development team to continue working with CalendarFX after the free trial period. It also removes some of the technical restrictions and includes online support and quick problem resolutions.

Runtime License
The runtime license allows the licensee to use CalendarFX for either a single off-the-shelf software product or for a single customer-specific project.

Source Code License
The source code license provides the licensee with the actual source code of CalendarFX. The licensee is free to modify the code in any way required. A source code license can only be purchased in combination with a development license.

Maintenance Plan
Licensees can subscribe to an annual maintenance plan, which will give them free access to the latest major releases.

Without a maintenance plan licensees will only receive minor and bug fix releases (1.0.0->1.1.0 or 1.0.0->1.0.1)

You will need to purchase a Maintenance Plan for each license you own, for example if you own a Development and Runtime License then you would need to purchase the Maintenance Plan for Development and the Maintenance plan for Runtime options.
