After successfully redeeming your gift card or gift certificate, the entire value of the card will be credited to your account. When the length of the subscription term ends, the premium subscription access to Calm will terminate unless a valid payment method has been provided. Only one gift card or gift certificate may be added to your account at a time. Once you have redeemed a Calm gift card or gift certificate, you must wait until the subscription access has ended to redeem another gift card or gift certificate.
