Grammarly is currently set to recurring payment cycles. Your subscription will automatically renew at the standard pricing and cadence unless you cancel before the end of the billing period. See our Terms of Service for more information.
The good news is that we’re here to help, so you can submit a support request if you have any further questions. You can also cancel your subscription to prevent future billing by following the steps described in this article: How do I cancel my Grammarly subscription?
