Chipmunk2D Pro License
Purchasing Chipmunk2D Pro grants the licensee the rights to use the iOS-built library on devices. The license may be purchased by an individual or organization and may be used on an unlimited number of titles. Licensees recieve the source code for the library (which is not available to free users), but they may not distribute the source code. A purchased license applies to all future upgrades to the major version of Chipmunk2D, although not necessarily to future related projects. You may not resell your Chipmunk2D Pro license. You may sell or otherwise distribute a product that uses Chipmunk2D or Chipmunk2D Pro, but you may not resell, lease, rent, transfer, or sublicense Chipmunk2D Pro itself. Bundling Chipmunk2D Pro into another development toolkit, SDK, or engine that you are selling as a product is not permitted. For example, you can't purchase a license to Chipmunk2D Pro, rebrand it, and sell it as a physics engine. If you are seeking an exception, please contact us via email and we'd be happy to work something out.
