recurring charges

nodalbot uses by default recurring charges, when you add a credit card your account settings will be set as recurring charges enabled.

In your account settings you can disable this option anytime, and as soon as your current period ends your account will return to free version and you won't be charged again.

When you wish to switch to professional version again, you can just reenable this option, you will be charged automatically and your account will be swicthed to professional version.
