6. Sessions in the Widget are managed by a temporary identifier (sessionId) held in the browser’s memory. This identifier is lost when the page is reloaded and is not stored in any persistent storage such as cookies, localStorage, or sessionStorage.
7. In connection with HTTP communication from a Widget Visitor’s browser to our servers, the source IP address, user agent, referrer, and similar information are recorded in our access logs. We use this information only for purposes such as rate limiting, detecting misuse and attacks, investigating technical failures, and otherwise ensuring the stable operation of the Service, and we do not store it in a database for the purpose of persistently identifying individual Widget Visitors.

Article 7 (Use of the API and MCP)

1. The API and the MCP Server (collectively, the “API Services”) may be used only by Users who have subscribed to a paid plan prescribed by us.
2. Use of the API Services requires authentication by an authentication method provided by us (an Access Token, OAuth authentication, or another method designated by us). Users shall strictly manage their authentication credentials at their own responsibility. We are not liable for any damage arising from a User’s disclosure of its authentication credentials to a third party.
3. If a User discovers that an Access Token has been leaked or may have been leaked, the User shall immediately reissue the Access Token. If the User is using OAuth authentication, the User shall promptly revoke the authorization granted to the MCP Client.
4. Users shall not embed Access Tokens directly in source code or commit them to a public repository.
5. When accessing the API Services using OAuth authentication, Users shall comply with the following:
   • To use the features of the Service only within the scope displayed on the authorization screen
   • To appropriately manage third-party applications (including MCP Clients) to which authorization has been granted, and to promptly revoke authorizations that are no longer needed
   • That, when the Service is accessed via a third-party application (including an MCP Client), the handling of User Data in that third-party application is the User’s responsibility and we bear no liability whatsoever
6. We may set limits on the number of uses and other limits (“Rate Limits”) for the stable operation of the API Services. Details of the Rate Limits are set out in the API documentation separately provided by us, and Users shall comply with them. We may change the Rate Limits in consideration of the usage of the Service and other circumstances. An update to the API documentation constitutes notice of any such change.
7. Answers to natural-language searches through the API Services are reference information generated by AI, and we do not guarantee their accuracy, completeness, or timeliness. Users shall make any decisions or take any actions based on the content of answers at their own responsibility.
8. When we change or discontinue a version of the API Services, we will give advance notice as follows:
   • Discontinuation of a major version: notice at least 12 months before the discontinuation date
   • Change to a minor version: notice at least 6 months before the change date
   • Where an urgent response is required for security reasons, we may make changes without advance notice.

Article 8 (Handling of User Data)

1. All intellectual property rights and any other rights in User Data belong to the User or to the legitimate right holder of that data. We do not acquire any rights in User Data. The same applies to data accessed or uploaded through the API and the MCP Server.
2. Users grant us a non-exclusive license to use User Data to the extent necessary to provide the Service (including analyzing documents, creating search indexes, providing context to AI, presenting search results, and making backups).
3. We handle User Data and chat content obtained through the Widget (collectively, “User Content”) as follows:
   • We do not use User Content to learn, train, or fine-tune any external AI model provided by us or by a third party
   • We do not use User Content for advertising or marketing purposes
   • We do not sell or provide User Content to third parties
4. As a general rule, we do not view the body of User Content. Our officers and employees do not view the body of User Content for purposes such as maintaining or improving the quality of the Service, improving the accuracy of AI answers, or statistical analysis. Notwithstanding the preceding paragraph, only in the cases set out in the following items may we, through the minimum number of authorized officers and employees, view and process the body of User Content to the minimum extent necessary:
   • Where necessary to investigate, recover from, and prevent the recurrence of technical failures, defects, data corruption, and the like in the Service
   • Where necessary to detect, investigate, and respond to misuse, violations of these Terms or guidelines, violations of laws and regulations, or security incidents
   • Where necessary to respond to a court order or to a request based on laws and regulations from an investigative authority or other public authority
5. For the officers and employees who carry out the viewing described in the preceding paragraph, we implement management based on internal rules, including confidentiality obligations, minimization of access rights, and the recording and retention of access logs.
6. Notwithstanding the preceding two paragraphs, a User with administrator rights for an organization/team (admin) may view, through the admin console of the Service, the chat content obtained through the Widgets associated with the organization/team to which that User belongs (messages sent by Widget Visitors and AI answers), as well as feedback provided by users on such Widgets. Such viewing shall be carried out within the scope of legitimate business purposes within the organization/team, and the administrator is responsible for complying with the Act on the Protection of Personal Information (個人情報の保護に関する法律, Act No. 57 of 2003; the “APPI”) and other applicable laws and regulations. The Widget Installer is obligated, in accordance with Article 6, Paragraph 2, to notify Widget Visitors in advance that such viewing may take place.
7. The Widget Installer is obligated, in accordance with Article 6, Paragraph 2, to notify Widget Visitors in its own privacy policy or similar document that we may view chat content under Paragraph 4 of this Article, and that administrators of the organization/team may view chat content from the admin console under the preceding paragraph.
8. We use the infrastructure of Amazon Web Services (AWS) for the Service. With respect to AWS’s policies on data processing, AWS’s terms of service and data processing agreement apply.
9. Based on AWS’s specifications, we have designed the Service so that User Data is not used for training AI models; however, we do not guarantee that we can fully exclude the possibility that this treatment may change due to changes in AWS’s specifications or the like.
10. When LINE Integration is used, messages sent by Users on LINE and answers from the Service are sent and received via servers operated by LY Corporation (LINEヤフー株式会社). The terms of use and privacy policy of LY Corporation apply to the handling of those messages.
11. When a User accesses data in the Service using an MCP Client, the terms of use and privacy policy of each AI service provider apply to the processing, storage, training, and other handling of User Data by the AI operating as that MCP Client (such as ChatGPT or Claude). We bear no liability whatsoever for the handling of User Data by the AI on the MCP Client side.

Article 9 (Confidentiality)

1. We shall treat User Data and Users’ confidential business information that we learn through the provision of the Service (“Confidential Information”) as strictly confidential, shall not use it beyond the extent necessary to provide the Service, and shall not disclose or leak it to any third party without the User’s prior written consent.
2. The preceding paragraph does not apply to information that falls under any of the following:
   • Information that was already publicly known at the time of disclosure, or that subsequently became publicly known through no fault attributable to us
   • Information that we already lawfully held at the time of disclosure
   • Information whose disclosure is required by laws and regulations, a court order, or a request from a government authority (provided, however, that we will make reasonable efforts to notify the User in advance to the extent possible)
3. We shall impose on our employees, subcontractors, and any other persons involved in providing the Service confidentiality obligations equivalent to those under this Article.
4. The confidentiality obligations under this Article survive the end of use of the Service.

Article 10 (Data Separation and Security)

1. We logically separate User Data between Corporate Accounts and manage it so that it is not mixed with the data of other Users.
2. For the security of User Data, we take technical and organizational security measures in accordance with our separately established Security Policy (in Japanese).
3. An overview of the security measures we take is as follows:
   • Encryption of data at rest and in transit
   • Access control and authentication
   • Recording of access logs
   • Periodic review of security measures
4. We store User Data in regions located in Japan. We also use models provided in regions located in Japan for generating answers by AI and for other processing. We may change the regions in which data is stored or processed for business or technical reasons. In that case, we will announce the details of the change and its effective date by posting on our website or by email notice at least 30 days before the effective date; provided, however, that this does not apply where an urgent change is necessary due to a failure, disaster, or other unavoidable reason, in which case we will announce the change promptly after it is made.

Article 11 (User Responsibilities)

1. Users use the Service at their own responsibility and bear all responsibility for the content of the data they upload to the Service.

Article 16 (Disclaimers)

1. The Service is provided “AS IS.” We make no warranty of any kind, whether express or implied, that the Service will be fit for any particular purpose of the User, that it will have the functions, accuracy, or usefulness the User expects, or that no defects will occur.
2. Results obtained by using Ask AI in the Service are reference information based on User Data, and we do not guarantee their accuracy, completeness, or timeliness. Users shall make decisions based on search results and the like at their own responsibility.
3. We will make reasonable efforts with respect to backups of User Data, but we do not guarantee that loss, damage, or destruction of data will be completely prevented. We recommend that Users keep backups of important data at their own responsibility.
4. When LINE Integration is used, LINE’s Letter Sealing (end-to-end encryption) does not apply to messages addressed to bots on the LINE platform. Accordingly, messages that Users send and receive on LINE are processed in decrypted form on the servers of LY Corporation. Users should take sufficient care not to send highly confidential information via LINE. We do not guarantee the security of communications on the LINE platform.
5. Answers by AI through a Widget are reference information based on documents uploaded by the Widget Installer and do not represent the official answers or views of the Widget Installer. We make no warranty whatsoever as to the accuracy, completeness, timeliness, or fitness for any particular purpose of answers by AI through a Widget.
6. We treat information that a Widget Visitor enters into a Widget (including where it contains personal information) as having been entered at the Widget Visitor’s own responsibility, and we are not liable for any damage arising from the entry of such information.

Article 17 (Limitation of Liability)

   • Where the User has violated these Terms
   • Where payment of fees is 60 days or more overdue
   • Any other case in which we reasonably determine that continuation of the Account is inappropriate
4. On the free plan, User Data is kept for 2 years from the Last Use Date. If there is no new use (an operation that updates the Last Use Date as defined in Article 2) within that period, we will notify the User by email 30 days and 7 days before the scheduled deletion date and then automatically delete the User Data (including original files, analysis data, and search indexes). The Account itself is not deleted, and the User may continue to use the Service by uploading documents again.

Notwithstanding the provisions of this Article, we retain information that must be retained under laws and regulations (such as records of transactions and payments and other accounting books and documents) for the period prescribed by the relevant laws and regulations. In that case, we do not use such information for any purpose other than its retention.

Article 19 (Exclusion of Anti-Social Forces)

1. Users represent and warrant that neither they (nor, in the case of a corporation, its officers or persons who effectively control its management) are an organized crime group (bōryokudan), a member of an organized crime group, a company affiliated with an organized crime group, a corporate racketeer (sōkaiya), or any other anti-social force (collectively, “Anti-Social Forces”), and that they have no relationship with Anti-Social Forces that should be socially condemned.
2. If a User breaches the preceding paragraph, we may suspend or delete the User’s Account without any demand or notice.

Article 20 (Amendments to these Terms)
