* Japanese Consumption Tax is not charged to schools and organizations located outside Japan. In that case, the fees are still the amounts above.

Fees for other services are shown on each service page or explained when you order.

See the Fee Schedule for the detailed rules.

Charges other than the price

Communication charges for internet access and similar costs.

If an individual service involves additional costs, we will explain them before you order.

Payment methods

Online payment (Stripe): credit card, Apple Pay, Google Pay, Link

Payment timing

The first fee is charged when you start a monthly subscription (including where the fee is ¥0), and after that fees are charged automatically on each renewal date. An increase during a billing period is charged together on the next renewal date, as set out in the Fee Schedule. While you use the Service only within the range in which no fees are charged, no payment procedure is needed.

Service delivery

Free features can be used from the time you sign in, and add-ons from the time you add them in the management site (depending on the feature, preparation may take a little time; see the Fee Schedule). For services that involve individual production, we will tell you the timing when we give you a quote.

Cancellation

Please request cancellation on the billing and cancellation page of the management site. The cancellation takes effect on the first renewal date after your request. Until then, you can continue to use the Service and withdraw the request.

Returns and refunds

Because of the nature of the Service, returns are not possible after payment. Fees already paid are not refunded, except where required by law or where there is a reason attributable to us.

System requirements

An internet connection and a supported device, and a Google Account or an email address that can receive email, are required.
