If you cancel within 48 hours of your order, you can request a refund through Google Play. And your refund reason needs to meet Google Refund Policy. All approved refunds are processed back using the original form of payment whenever that is possible.
If you cancel after 48 hours, your payment is non-refundable and your service will continue until the end of your contracted term.
If you have any problem with your refund, please feel free to contact support@pdfreaderpro.com.
