For on-premise deployment of the Admin Console, an additional one-time technical support fee equal to 15% of the total amount paid for the LynxPDF Services is required. This fee does not apply to Users deploying via the cloud.
The LynxPDF Services you have purchased provides the perpetual license of using those services. Details regarding the perpetual license are as follows:

Without the prior consent of Kdan, you may not sublicense or transfer the permanent license of the LynxPDF Services to any third party or transfer it to other unauthorized devices.
You may purchase additional licenses of the LynxPDF Services as needed through the Admin Console or the LynxPDF website and complete the payment process.
