Yes. Gecko Edge subscriptions renew automatically at the end of each billing period, and we charge the card you used at signup.
You can manage your subscription at any time. Bottom left, click the three dots next to your username and choose Manage Subscription. From there you can see your current plan or cancel the renewal (to update your payment method, contact support and we will send you a secure link). If you cancel, you keep full access for the remainder of the period you have paid for, and we take no further payment.
