Terms of service

1. Contract and seller

These terms apply to FDE Web, FDE Windows, AIRouter, Legal and other services supplied directly by ビリオン株式会社. The order, clearly disclosed special conditions, these terms and the activation/refund rules form the contract. Independently sold services follow the seller and terms identified in the order. Document precedence does not diminish explicit promises or statutory rights.

2. Accounts and organizations

Individual and organization-member accounts are mutually exclusive; migration requires confirming data, order and balance ownership. Individual paid services are for users aged 18 or older. Organization representatives must have authority to contract. Provide accurate necessary information, protect passwords and API credentials, and promptly report compromise.

Organizations manage members and seats within assigned authority. The service-provider administrator appoints or removes organization administrators. Administrative status alone does not grant access to every project or Legal case; external participants are limited to valid invitations.

3. Products and charging scope

FDE Web and FDE Windows have separate subscriptions. AIRouter service fees exclude actual model usage. FDE model fees depend on the selected connection. Downloading software does not itself grant paid access.

Legal is purchased by organizations per seat and period, with no independent personal subscription. Validly invited external participants are covered by the inviting organization and do not consume seats. The initial offering has no separate AI usage charge or points program, but this is not unlimited usage. Legal is software and does not include engagement of a lawyer or litigation representation.

4. Orders, prices and payments

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.

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.

Before purchasing, check the product, market, currency, seats, discounts, tax, total, service period and limits. Discounts follow the rules disclosed for that order. If we cannot accept an order, we notify you and handle any payment for undelivered services under the refund rules.

5. Activation and refunds

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.

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.

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.

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.

6. Model 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.

7. Content and AI output

You retain your existing rights in your content and must have authority to submit, process and share it. We process it as needed to provide services, maintain safety and meet legal obligations, and do not use customer projects, prompts or outputs to train general-purpose models. External providers’ retention and training terms depend on their actual service contracts.

AI may contain errors or omissions. Before executing code, filing formal legal documents or making important decisions, have outputs checked by an authorized, suitably competent person. We do not guarantee exclusive outputs, non-infringement or case outcomes. This does not waive our own delivery, security or contractual responsibilities.

8. Acceptable use and external services

Rights infringement, account theft, malware, unauthorized attacks and evasion of stated limits are prohibited. We apply necessary restrictions based on impact and offer a contact route to challenge decisions; urgent security or legal action may precede notice. Your own API key follows your provider contract. A third-party outage does not automatically remove our responsibility for services sold.

9. Changes, responsibility and disputes

We give advance notice of significant planned maintenance and important feature or general-term changes, normally at least 30 days for material changes. Urgent security or legal changes are notified as soon as practicable. If a paid product or a purchased core feature is discontinued without a reasonable substitute, we address refunds for undelivered services and necessary data export.

Each party remains responsible for its own contractual or legal breaches. We do not exclude liability that cannot lawfully be excluded, including intentional misconduct or gross negligence. Japanese law generally governs, while mandatory consumer protections and rights to bring proceedings remain intact. Support discussions do not exclude legal remedies. This version applies to orders confirmed under it after publication and does not retroactively change paid orders.
