When you create your 4ormat account you start with a free trial. No charges occur until the trial is over.
You can cancel your account at any time by sending us an email at firstname.lastname@example.org. We respond quickly to all requests.
Once you cancel you won’t be charged again, but you are responsible for whatever charges have already been incurred for the current billing period. For example, if you signup on the 20th of the month that means your billing cycle is on the 20th of every month. If you cancel your account on the 24th, you'll still have to pay for the current month, but you won't be charged again after that.
