You can stop your auto-renewal at any time. This change will not affect your active services in any way, they will still remain fully active until your account’s expiration date.
To disable the automatic billing for your hosting account, domain, or another service, open Billing → Services page. There, click on the Options button (⋮) in front of the service in question, and choose Renewal Settings:
Once there, simply click on the toggle button near Activate auto-renewal, making it gray:
And save changes. Congratulations, automatic renewal is successfully disabled for the chosen service!
If you do not intend to stop using services, it's recommended to keep auto-renewal enabled to prevent domain expiry and website downtime
