You can cancel a Priority Review subscription at any time, including before your first charge has been processed. There is no waiting period and no minimum term.
Cancelling stops every future charge straight away and deletes the card we hold for the subscription in the same step. Priority Review keeps covering your new applications until the end of the month you already paid for, then ends.
If this month's charge was already authorised when you cancel, that one still completes — it is the last one, and the cancel screen tells you the amount. Payments already made are not refunded (the Refund & Cancellation Policy, /legal/refund-policy).
To avoid the next charge, cancel before the next charge date shown on your subscription page.
Send a change request: billing mistakes our records prove are refunded automatically, and a person answers the rest within two business days.
