Math Playground memberships are free during the 7 day trial period. To avoid a credit card charge, you must cancel your account before the end of the trial. Payment is processed immediately following the trial.
When you sign up for a membership, you are given the choice of an annual or monthly payment plan. Annual payment plans are billed once per year and offer a significant savings compared to monthly plans. However, they require a larger payment upfront.
Both payment plans automatically renew until you cancel your membership. After the 30 day money back guarantee has expired, there are no refunds for either plan.
