Monthly plans. No refund. Cancelling stops the next charge.
6-month plans. Refundable within 30 days of the charge, including renewals. We keep 20%. You stay on the plan until the end of the current calendar month and then move to Free.
12-month plans. The same 30 days, and we keep 15%.
After 30 days there is no refund, but you can turn renewal off at any time. Prices never include tax; what tax applies depends on your country.
