+## FAQs
+
+### Who can redeem a gift code?
+
+Anyone who doesn't have a Notesnook Pro subscription can redeem a gift code and upgrade their account. One user can only redeem a single gift code at a time.
+
+### Is there an expiry date to a gift code?
+
+No. Each gift code is valid for an infinite amount of time until it is claimed by a user.
+
+### What can I do with a gift code?
+
+Whatever you like. Sell it, gift it, use it.
+
+### Can I refund a gift code I purchased?
+
+No. Gift codes are non-refundable.
+
+### Are gift cards auto-renewable?
+
+No. Gift cards are a one-time purchase.
+
+### Can I use cryptocurrency to purchase a gift card?
+
+Currently, no. But we are actively working on a solution to support this so stay tuned.
