At PDF.js Express we do not offer refunds. We do offer a free trial where you can download PDF.js Express, deploy it in your environment and spend as much time as you need to evaluate its fit. We are committed to providing you with support during the evaluation stage of your project, so you can be sure that PDF.js Express meets your requirements. Licensing only kicks in when you are ready to deploy to production.
If you no longer wish to use PDF.js Express, you may cancel at any time. If you cancel your plan before the next renewal cycle, you will retain access to the paid features of PDF.js Express until the end of your subscription period. When your subscription expires, you will lose access to paid features.
