After you confirm your cancellation, your subscription will remain active for the amount you already paid for. You will not lose benefits during your active period. At the end of the billing period, your subscription benefits will expire. You will still have access to free features like assignments, selective games, and worksheets even after your subscription expires. However, you will not access to any premium benefits like assessments, workbooks, and exclusive games for students.
Per our payment terms, all transactions are non-refundable. Customers are responsible for all transactions that occur prior to cancellation: https://www.mathgames.com/payment-terms.html
