FunnelFlux doesn't have account suspension or temporary pauses to the subscription.
However, you can cancel at any time.
Cancelling will result in your license expiring at the end of the billing period (with a few days grace to allow for renewals e.g. when credit cards expire, or you need to change billing method).
Expiration of a license will stop you from being able to log into your tracker. However, it will not stop tracking from working, nor will any of your data be affected -- it just stops you using the tracker dashboard/UI.
So, you don't need to worry about your tracker becoming non-functional or losing data as a result of licensing.
You can cancel your subscription then re-subscribe at any time via your members portal here:
