秋山黄色の裏垢 is the official fan club app for 秋山黄色. This iPhone app offers a wide range of exclusive content for registered members, including the latest news, blogs, and radio shows that can only be accessed through the app.

The app also offers a premium membership option, which provides additional benefits. For a monthly fee of 500 yen (including tax) or an annual fee of 5,000 yen (including tax), premium members can enjoy automatic renewal of their membership and access to premium content.

Please note that the premium membership will be automatically renewed on a monthly or annual basis unless canceled at least 24 hours before the end of the current period. The payment for the automatic renewal will be charged to the user's iTunes account within 24 hours prior to the end of the current period.

To check the status of the premium membership and cancel or manage the subscription, users can visit the designated page in the App Store app or the iTunes app. Unfortunately, cancellation of the current month's premium membership is not accepted, and the cancellation process will be carried out after the end of the contract period.
