    How often am I billed?+

    Codstak Pro is billed monthly and renews automatically until you cancel.

    Can I cancel at any time?+

    Yes. You can manage or cancel your subscription from your Codstak profile. After cancellation, access continues through the end of the period you already paid for.

    What is the 7-day refund policy?+

    Your initial Codstak Pro purchase is eligible for a full refund when you request it within seven calendar days of purchase. Email support@codstak.com from the address on your account. Refunds requested after that window are not guaranteed, except where required by law.

    Does Codstak Pro guarantee an interview or job outcome?+
