If you wish to cancel your Cocolyze subscription you can do it directly in your Account > Billing > Cancel subscription.
Your subscription will be active until the end of your subscription period (for example: you cancel on the 7th of the month and your renewal is due on the 30th of the month. Your account will be active until the 30th).
Once you have reached the end of your subscription period, your account will not be renewed and all rank tracking will be stopped. There will be no further analyzes or access to data.
