Your subscription will auto-renew only if you select the AutoPay option during the purchase process.

If AutoPay is enabled, your plan will automatically renew at the end of the billing cycle, and the applicable amount will be charged to your payment method.

If AutoPay is not selected, your plan will not renew automatically. Once the plan expires, you can simply purchase a new plan whenever you wish. In this case, you do not need to worry about automatic charges or subscription cancellation emails.
