If you're looking for a refund on a Noteflight Learn or Premium subscription, you can request one 30 days after signing up/renewing to get your money back. Here's how:
Log in to Noteflight and click on your Profile picture in the upper right corner, then click "Account."
Choose "Subscription" in the left-hand menu.
There, you will see a link saying "Contact Sales for Refund".
You can then email sales requesting a refund and you will receive an email back confirming your cancellation and the amount will be refunded to your credit card within 3 days. If you have any problems with this process, please email email@example.com.
