Terms of Service

These Terms apply to all relationships between the Operator and users concerning the use of the Service. Any individual rules or guidelines separately established by the Operator on the Service form part of these Terms.

• "Firm" means an organization (such as a tax accounting or accounting firm) that enters into a service agreement with the Operator for the Service.
• "User" collectively means an individual who belongs to a Firm and uses the Service (a "Firm User") and an individual who belongs to a Firm's client and uses the Service upon the Firm's invitation (a "Client User").
• "Content" means information that Users create, register, or send on the Service.

• Users shall register their accounts with accurate and up-to-date information.
• Users shall manage their credentials appropriately at their own responsibility and shall not allow third parties to use them.
• Users shall bear responsibility for any damages arising from inadequate management of their accounts.

By connecting their own Google account to the Service, users can send emails to clients from their own Gmail account. For firms that integrate with Google Workspace, additional features are available, including importing email exchanges with clients and connecting Google Drive (Shared Drive) as a storage location for documents. The email import feature is currently offered to a limited number of firms, with availability expanding progressively. Extended features such as the Google Drive (Shared Drive) integration are currently in preparation. The handling of information obtained through this integration is as set forth in §3 of the Privacy Policy.

• Google account integration, including email import, is opt-in for each individual user, and users may disconnect the integration at any time.
• Shared mailboxes (such as info@) and any other mail account that the user does not solely control are not subject to email import.
• If a user leaves the firm, or the firm disables that user's account, further email import stops. Imported email data may continue to be retained by the firm as a business record, remaining visible only to the parties involved in the original exchange.
• Firm users belonging to a firm that connects Google Drive (Shared Drive) are, in principle, required to sign in with their Google account (single sign-on), except for users individually exempted by the firm's administrator (owners cannot be exempted).
• Users are responsible for the security of the Google Account (including any Google Workspace account) they use to connect to the Service, such as configuring passwords and two-factor authentication. The Operator is not liable for any damages incurred by users arising from a compromise of that Google Account.

The Service is currently provided free of charge. If the Operator offers paid features or plans, it will separately establish and display the fees and payment conditions on the Service.

Users shall not engage in any of the following acts when using the Service.

• Acts that violate laws or public order and morals
• Acts related to criminal activity
• Acts that infringe the intellectual property rights, privacy, honor, or other rights of the Operator or any third party
• Acts that interfere with the operation of the Service, unauthorized access, or other similar acts
• Acts of sending spam or other inappropriate emails through the Service
• Any other act that the Operator deems inappropriate

The Operator may suspend or interrupt all or part of the Service without prior notice to users in the event of system maintenance, force majeure such as natural disasters, or other unavoidable circumstances.

• The Operator does not warrant, expressly or impliedly, that the Service is free from de facto or legal defects.
• Except in cases of the Operator's willful misconduct or gross negligence, the Operator shall not be liable for any damages incurred by users arising from the Service.
• The Operator shall not be liable for any malfunctions arising from changes in specifications or failures of Google or other external services.

The Operator may change the content of the Service or terminate its provision upon appropriate notice to users.

The Operator may change these Terms without notice to users when it deems necessary. The amended Terms take effect when posted on the Service.

These Terms shall be governed by and construed in accordance with the laws of Japan. In the event of any dispute concerning the Service, the court having jurisdiction over the location of the Operator shall be the exclusive agreed jurisdictional court.
