What is your policy for annual support-renewal / upgrades?
When you purchase the library, 3 months of free support is included. This is normally enough to get the library integrated into your application and to work out any issues that may come up. Support includes answers to any questions that may come up, priority bug fixes and free upgrades during the 3 month period.
Additionally, we also offer extended support renewable on a yearly basis. The extended support includes the same items as the initial 3 month support and is priced at 15% of the purchase price per year.
Is there an expiry date for the license?
There is no expiration on the license.
