After the free trial period ends, a tool usage fee will be charged.
(For the old Auto plan, if "Advertising is being delivered through Shirofune")
As long as you are not in those states, you will not be charged a tool usage fee at the end of the free trial period.
* In addition to the tool usage fee, the old Auto plan will incur "advertising fee settlement fee / account management fee" (5% of monthly advertising fee). In addition, it does not occur if the advertising cost for that month is 0 yen.
