Our licensing model is designed to offer flexibility and long-term value for our users. 

When you purchase the ChatMotor SDK, you receive a perpetual license for the specific version available at the time of your purchase. This means you can use the software indefinitely without any recurring fees. There are no runtime fees, ensuring that you can deploy and scale your applications without any additional costs.

Additionally, for the first year after your purchase, you may access to software new versions, ensuring you have access to the latest features, bug fixes, and support. 

After the initial year, you have the option to purchase an upgrade or a maintenance plan to continue receiving updates and support, allowing you to keep your software current and secure.
