The expiration date for your credits is 13 months from the date your subscription credit was purchased. If your subscription is cancelled and no longer active, you will have 30 days to redeem your available credits from the date the subscription was cancelled.
To see when your credits expire, follow the below steps for both the iOS and Android Chatbooks Apps:
Tap into your subscription.
Tap into the Settings (gear icon) in the upper right corner
Tap into "Subscription book credits"
There you will see your available credits and when they expire.
Here's a video how-to on finding your available credits as well:
How to find expiring subscription credits.
Why do credits expire? Printing and shipping costs change over time, so credits are priced to the costs at the time you buy them. Expiration dates also give a friendly nudge to print your memories.
Need more time? If your subscription is active, you can extend a credit by 30 days. See Can I extend the subscription credit expiration date?
Note: If your subscription started with a promotional offer, any credits purchased as part of the promotion expire immediately when you cancel. Credits purchased outside the promotion expire 30 days after you cancel.
