Qualified invoice registration

We are not registered as a qualified invoice issuer in Japan and do not have a T registration number.

Contact and support hours

Support is provided by email at sales@pmo.dev; we do not operate a telephone support line. You may email at any time. Staffed hours are 10:00–17:00 JST on Japanese business days, excluding weekends, Japanese public holidays and announced closures. We give an initial response to general, refund and privacy inquiries within two business days. This is not a promise of resolution or receipt of a refund within that period.

Services supplied

FDE Web, FDE Windows, AIRouter, Legal and other services are separate subscriptions, delivered online or by software download, with no physical shipment. Legal is case, document and workflow software for organizations.

Prices and tax

The pricing and order-confirmation pages show amounts by market, product, customer type, period and seats. Base prices exclude tax; Japanese prices also show 10% tax and the total. Price-validity dates are separate from the service period.

Additional costs

Customers cover connectivity, devices and bank transfer fees. AIR model usage and connected FDE model services are charged separately. Other charges must be disclosed before purchase.

Payment methods and timing

For bank transfers, follow the order instructions and pay within seven calendar days of the payment notice. Online methods, including cards, are available only when activated and shown at checkout. Pay only the recipient and account specified in the order. Do not repeat a payment because a page has not yet updated.

Delivery and activation

We confirm offline payments within one business day after complete reconciliation information is received. Access normally activates within five minutes after payment, account eligibility and required approvals are confirmed. A prepaid future period begins on its agreed date without replacing the current period. If we cannot deliver within one business day after all prerequisites are met, you may choose to wait or cancel the undelivered portion for a refund.

Service periods and renewal

Purchase one, three, six or twelve months in a single payment and renew manually. There is no automatic renewal or charge. Price validity is different from your purchased service period. Later price changes do not reprice paid orders or change their agreed service periods.

Cancellation and refunds

An independent usage-based order that has not started and has not been used is fully refundable. Time-based services are refundable only when there is an eligible reason, such as our inability to deliver. We deduct the value of days actually delivered from the original amount paid and refund the remainder with the corresponding tax. Undelivered days are not deducted. Stopping for personal reasons after normal service has begun is not refundable; access remains available until the purchased period ends.

Billing errors and non-delivery

We correct duplicate or incorrect charges and refund the excess. For non-delivery or services that do not conform to the agreement, we provide an appropriate repair, an agreed alternative or a corresponding refund. These rules do not restrict cancellation, refund or other rights provided by applicable law.

Refund procedure

Email your order number and reason to sales@pmo.dev. Closing your account is not required. We respond initially within two business days and initiate an approved refund within five business days. Receipt depends on the bank or payment provider. Refunds normally go to the original payment method; organization funds are not returned to ordinary members’ personal accounts. We charge no additional subscription refund handling fee and cover transfer fees for refunds caused by us.

System requirements and limits

Current FDE Windows distributions support Windows 10/11 x64; see their download instructions. Web products require connectivity and a compatible browser. Device, concurrency, traffic, storage, model and regional limits follow the pre-order product information and order.

AIR balances and points

AIRouter subscriptions, model-usage balances and free points are separate. Actual model usage is not included in the subscription fee. Confirm permitted uses, validity and applicable refund conditions before topping up. Subscription rules on this page do not make balances freely withdrawable. Free points cannot be exchanged for cash or transferred to others.
