Billing and cancellation
Teacher membership
The membership costs $9.99 per month during the school year and renews automatically until you cancel. There is no scheduled renewal charge in July or August, and access stays active. New memberships, including summer signups, are charged $9.99 when activated. A complete September–August cycle totals $99.90.
Canceling
Open Account Settings, choose Manage Billing, and cancel in the Stripe portal. Stripe shows the date your current paid period ends before you confirm. Canceling stops future charges and leaves access in place through the end of the period you have already paid for; it does not issue an automatic refund for time already used.
Refunds
If you were charged in error, charged after canceling, or the service was unusable for a period you paid for, email howe2math Support and it will be reviewed. The full policy is in the terms of service.
Payment problems
If a payment fails, worksheet generation may be paused while Stripe retries the payment or you update the card. Account access and billing status are controlled by verified Stripe events.
Contact
Billing questions go to howe2math Support. Include the email address on the account and the date of the charge.
