Most credits expire 1 year from the date they are issued. The expiration date of credits issued from a perk, however, will depend on the individual perk program. Please refer to the expiration date in your perk activation email. Please note that you cannot extend or modify the expiration date of credits under any circumstances. Once credits expire, they cannot be reactivated.
Credits can be applied toward monthly subscriptions, including app plans and plugins. However, they cannot be used for annual app plans, templates, perpetual plugin licenses, or coaching sessions.
You can also find your credit balance and expiration date on your Account page → Billing tab under "Current credit balance".
