Price	Developer plan: USD 15.00 per month (exclusive of tax). The base fee includes 1,000 downloads per month; additional downloads are metered at USD 0.001 per download. For customers in Japan, Japanese consumption tax (10%) is added, and the tax-inclusive total is shown on the Stripe Checkout screen before you complete your order. Current pricing and other plans are published at https://models.manashiki.com/pricing.
Fees other than the listed price	(1) Consumption tax (customers in Japan); (2) internet/communication charges required to use the service (borne by the customer); (3) for USD-denominated charges, currency-conversion amounts and foreign-transaction fees determined by your card issuer. Payment processing fees are borne by us and are not charged to you.
Payment methods	Credit card via Stripe Checkout (Visa / Mastercard / American Express / JCB, etc.). Card details are never stored on our servers; payments are processed by Stripe.
Payment timing	Base subscription fee: charged at sign-up for the first period, then automatically in advance on each monthly renewal date. Metered usage (downloads beyond the 1,000 included per month): finalized at the end of each billing period based on actual usage and charged in arrears together with the next invoice.
Service delivery	The service is available immediately after payment is confirmed (API key issuance and service use become available as soon as we receive Stripe's payment-completion notification). Maintenance and incident information is announced within the service.
Contract term and automatic renewal	This is a monthly subscription that renews automatically. Unless you cancel, it renews indefinitely on the same terms, and the base fee is charged on each renewal. There is no fixed offer period.
Cancellation	You can cancel at any time online via the Stripe Customer Portal (accessible from the Billing screen of your dashboard at https://models.manashiki.com/dash). Cancellation takes effect at the end of the current billing period; if completed before the next renewal, no further charges occur. No partial-period (pro-rata) refunds are provided for mid-period cancellation, but you retain access until the end of the paid period. There is no termination fee.
Returns and refunds	Because this service consists of digital content (services), fees already paid are in principle non-refundable for customer-convenience reasons. As this is a distance sale under Japanese law, the cooling-off system does not apply. Exception: if you request a refund within 7 days of your initial sign-up and your cumulative download count is fewer than 100, the base subscription fee will be refunded in full. Metered usage charges (e.g., downloads beyond the included allowance) are non-refundable, as those services have already been provided.
Defects and outages (special terms on conformity liability)	If the service is unavailable for 24 consecutive hours or more due to causes attributable to us, we will refund the monthly base fee pro rata for the downtime (based on our uptime records). All other handling of defects and non-conformity is governed by our Terms of Service (https://models.manashiki.com/legal/terms).
Operating environment	A client environment supporting HTTP/2 and TLS 1.3 is required. SDK support: iOS 17+ / macOS 14+ / Android 8+ / Node.js 20+ / current modern browsers. Network access to Cloudflare (R2) is required.
Other terms of sale	If a card payment fails, API keys are suspended after a 7-day grace period. For full terms of service, see https://models.manashiki.com/legal/terms.

Additional information for international customers

Automatic renewal disclosure	Your subscription renews automatically at the end of each monthly billing period and continues until canceled. You will be charged the base fee in advance on each renewal date, plus metered usage in arrears. You can cancel at any time via the Stripe Customer Portal; cancellation takes effect at the end of the current billing period, and you retain access until then. Except as stated in the refund policy above or as required by law, fees already paid are non-refundable.
Governing law and jurisdiction	This disclosure and the underlying subscription contract are governed by the laws of Japan. As set out in the Terms of Service, the Tokyo District Court or Tokyo Summary Court has exclusive agreed jurisdiction in the first instance.
Currency and taxes	All prices are listed and charged in US dollars (USD) and are exclusive of applicable taxes. Japanese consumption tax (10%) is added for customers in Japan and shown at checkout. If your payment card is denominated in a currency other than USD, your card issuer's exchange rate and any foreign-transaction fees apply. You are responsible for any taxes applicable in your own jurisdiction.
