How long do I remain a VIP?

Your VIP points will not expire as long as you make at least one purchase per calendar month. If you don’t make a purchase in a month, your VIP status will be downgraded to the next highest status on the first day of the following month.
However, all you need is one purchase to recover your previous VIP status, because your VIP points are reset to the highest possible number of points of the lower VIP status.

For example: You have Gold VIP status and 950 VIP points. If you don’t buy Twists for a calendar month, you will be moved down to Silver VIP status with 759 VIP points.
