• 1. What is a subscription license?

    Customers can purchase subscription licenses for various time periods, and are entitled to use the software during the agreed upon time period. The subscription payment includes software licenses, access to support services, and new versions of the software as they are released. When the subscription expires, the customer does not have access to use or distribute commercial software developed with Qt.

  • 10. What happens if I make a late payment?  Can I renew my Product Maintenance or my Subscription if it has expired?

    If your subscription expires, your access to Qt will be suspended after the subscription date. To re-subscribe at a later date, please contact your Renewal Representative. You can contact us through our Contact Us page.

  • 2. What is the difference between maintenance and subscription?

    Subscription licenses give you access to Qt over a set period of time and are available for your Qt products. Maintenance is included in the price of a subscription license, keeping you up-to-date and giving you access to Qt’s ongoing product releases and support services at no additional cost.

     For perpetual licenses, maintenance is what gives you continued access to technical support, Qt feature and patch releases in Qt 5.

  • 4. If I don't convert to subscription, can I still use my perpetual license?

If your Qt licenses are perpetual, you may continue to use the product in perpetuity after your maintenance expires.  Access to product and technical support will only be available via the purchase of an Extended Maintenance Contract for software releases that are end-of-life. If you opt not to renew, please note that Qt will not guarantee to support software versions acquired with a perpetual license.
