Apmetrix Billing Policy
Your account will not be billed while you are in development mode and will only begin once your game or app has been released and is made available for sale.
Furthermore, if your total number of monthly unique users is below 100,000, your credit card will never be billed as long as the total number of monthly unique users are below that threshold.
If your total unique monthly users exceed 100,000 within any given 30 day period, you will be charged based upon the total number of monthly unique users for that period as stated in our pricing schedule.
If at any time your total monthly unique users drops back below 100,000, you will not be charged for that period.
