To cancel any Zyro subscription, all you need to do is deactivate the auto-renewal option and let it expire.
To do so, complete these three simple steps:
Go to your Subscriptions page.
Find the service in question.
Turn the auto-renewal option off.
The service will remain active until its expiration date, and after that, it will be canceled.
Note: The domain renewal fee is charged 30 days before the domain's expiration date in order to ensure uninterrupted domain service. If you decide to cancel your domain name, make sure to disable its auto-renewal by then.
