We charge a monthly usage fee based on the number of devices that use the Riiiver SDK during that month.

The total number of devices that used the Riiiver SDK is determined at the end of the month, and we will charge the Developer the following month based on that number.

* In order to give sufficient notice to Riiiver community members who may be may using iiidea containing a Piece you made which would become unavailable upon cancellation of your SDK usage, the following rules have been established:
・ If you apply for cancellation by the 15th of the month, cancellation will occur at the end of the next month.
・ If you apply for cancellation on the 16th of the month or later, cancellation will occur on the last day of the month after the next month.
・ If you wish to cancel at the end of a specified month, you must apply at least 3 months prior to the desired cancellation month.

・ If payment is delayed, Developer will be charged an additional 14.6% of the contract fee in late penalties.
・ If payment is not made for a Piece for three months, that Piece will be suspended.
・ However, SDK usage fees including late penalties will still accrue during the suspension period for an additional two months.
・ If the suspended Developer does not pay all charges including late penalties, the contract may be cancelled.
