D2B Terms of Service

Article 1 Application

• The Terms govern the rights and obligations between the Company and users (defined in Article 2) regarding use of the Service, and apply to every relationship between a user and the Company concerning the Service.
• Rules, price lists and other provisions about the Service that the Company posts from time to time in the App (defined in Article 2) or on its website form part of the Terms.

Article 2 Definitions

In the Terms, the following words have the following meanings.

• “Service” means the service named “D2B” provided by the Company, which ingests a user’s data, manages, transforms and analyses it as tabular data and makes it available to AI agents (including the service after any change of name or content, for whatever reason).
• “App” means the web application, API, command-line tool, SDK, MCP server and any other software and interfaces the Company provides for the Service.
• “User” means an individual, corporation or other organisation registered as a user of the Service under Article 3.
• “User Data” means files, tables, transform definitions, charts, reports and other data that a user uploads to, connects to or enters into the Service, or generates on it.
• “Agent” means an AI agent, program, script or other automated means that a user connects to the Service using the user’s credentials.
• “External Service” means a service designated by the Company and provided by another business, with functions such as user authentication, payment, file storage or processing by large language models, used in operating the Service.
• “External Provider” means the provider of an External Service.
• “External Terms” means the terms governing the relationship between a user and an External Provider.
• “Intellectual Property Rights” means copyrights, patents, utility model rights, trademarks, design rights and all other intellectual property rights (including the right to acquire them or to apply for their registration).
• “Registration Information” means the Registration Information defined in Article 3.
• “Usage Agreement” means the Usage Agreement defined in Article 3.

Article 3 Registration and formation of the Usage Agreement

• A person who wishes to use the Service (an “Applicant”) may apply to register by agreeing to observe the Terms and providing the information the Company designates (“Registration Information”) by the method the Company prescribes (including signing in with an External Service account).
• An Applicant registering on behalf of a corporation or other organisation represents and warrants that they are authorised to agree to the Terms for that organisation; the organisation is then the User.
• Applicants must provide true, accurate and current information. A minor must obtain the consent of a legal representative.
• The Usage Agreement — the contract for use of the Service under the Terms — is formed when the Company accepts the application and registration is complete.
• The Company may refuse registration, or suspend use of the Service or cancel a User’s registration without prior notice or demand, where the Applicant or User:

• is, in the Company’s judgment, likely to breach the Terms;
• has provided Registration Information that is false, erroneous or incomplete in whole or in part;
• has previously had a registration cancelled;
• is an anti-social force (an organised crime group, its members or associates, affiliated companies, corporate racketeers, groups engaging in criminal activities under the pretext of social movements, special intelligence crime groups, or any other group or individual pursuing economic gain through violence, coercion or fraud; the same applies below), or is, in the Company’s judgment, involved with anti-social forces through funding, cooperation or otherwise;
• is otherwise reasonably judged by the Company to be unsuitable for registration.

Users must notify the Company without delay, by the prescribed method, of any change to their Registration Information and submit any documents the Company requests.

Article 4 Accounts and credentials

• Users manage and keep their accounts, passwords, API keys, access tokens and other credentials (“Credentials”) at their own responsibility and must not let third parties use them, or lend, transfer, rename, sell or otherwise dispose of them, except as the Company permits.
• Where a User lets an Agent use the Service with the User’s Credentials, every act of that Agent on the Service is deemed the User’s own act. The User sets and manages the scope of authority granted to Agents at their own responsibility.
• Users bear liability for damage caused by insufficient management or mistaken use of Credentials or by third-party use; the Company is not liable except in cases of its wilful misconduct or gross negligence.
• A User who learns that Credentials have been stolen or used by a third party must immediately revoke them, notify the Company and follow the Company’s instructions.

Article 5 Workspaces and members

• Within the limits the Company sets, Users may create workspaces and invite others as members or guests. Invitees are bound by the Terms when using the Service.
• A workspace administrator is responsible for member permissions, the handling of data and the payment of fees for that workspace.
• At an administrator’s request the Company may add, change or remove members and guests of the workspace and perform other operations, and is not liable for them except in cases of its wilful misconduct or gross negligence.

Article 6 Fees and payment

• Users of paid plans or features pay the fees in the price list the Company posts in the App or on its website, by the method the Company designates (including credit-card payment through an External Service).
• Paid plans renew automatically on the same conditions at the end of each monthly or annual term unless the User cancels. On cancellation during a term the Service remains available until the end of that term; fees already paid are not refunded.
• Usage-based charges (including purchases of additional credits, auto-recharge and metered data operations) are billed at the times the Company sets, based on usage the Company measures.
• The Company may change fees or the method of charging, and will announce the change by its prescribed method a reasonable period before it takes effect.
• If a User is late paying fees, the Company may, after notifying the User, suspend all or part of the Service or move the User to the free plan.
• Consumption tax or other taxes may apply to fees as required by law; the amount is shown at checkout.

Article 7 Free plan and trials

• The Company may offer a free plan or a trial period. The free plan is subject to the limits on features, capacity, number of uses and otherwise that the Company sets.
• For the free plan, the Company may suspend accounts unused for a set period and, after prior notice by its prescribed method, delete their User Data.

Article 8 User Data

• Rights in User Data belong to the User or to those who licensed it to the User. The User grants the Company the right to store, copy, transform, transmit and otherwise process User Data to the extent necessary to provide, maintain, improve and protect the Service and to perform the Terms.
• Users represent and warrant that they are authorised to upload, connect or enter their User Data, and that it does not infringe third-party rights or violate the law.
• Users back up their User Data at their own responsibility. Except as a function of the Service, the Company does not guarantee the preservation of User Data.
• The Company may use and publish User Data and usage of the Service as statistical information from which no individual or organisation can be identified, at its discretion, and Users will not object.

Article 9 AI features

• The Service uses large language models and other AI technologies (“AI Features”) to structure, transform, analyse and visualise User Data and to generate text. To provide AI Features, all or part of User Data may be sent to External Providers the Company designates; their handling of it is governed by their External Terms and the Company’s Privacy Policy.
• Output of AI Features is the result of probabilistic processing; the Company does not guarantee its accuracy, completeness, legality or fitness for a particular purpose. Users verify such output at their own responsibility and decide whether to use it.
• Users must not use AI Features for purposes that violate the law, infringe third-party rights or breach an External Provider’s External Terms.

Article 10 Prohibited acts

Users must not do any of the following when using the Service.

• Create or hold multiple accounts without the Company’s permission, or share Credentials with third parties except as the Company permits.
• Use a payment method or an External Service account they are not authorised to use.
• Upload or connect third-party data without authority.
• Infringe the Intellectual Property Rights, portrait rights, privacy, honour or other rights or interests of the Company, other Users, External Providers or other third parties (including acts that directly or indirectly cause such infringement).
• Engage in acts related to crime or contrary to public order and morals.
• Violate laws or the internal rules of an industry body to which the Company or the User belongs.
• Send information containing computer viruses or other harmful programs.
• Disassemble, decompile or reverse-engineer systems of the Service.
• Circumvent rate limits or other usage limits the Company sets, or place excessive load on the Service.
• Collect data through the Service for the purpose of developing or providing a service that competes with the Company.
• Engage in acts reasonably judged likely to obstruct the Company’s operation of the Service.
• Engage in any other act the Company reasonably judges inappropriate.

Article 11 Suspension of the Service

• The Company may suspend or interrupt all or part of the Service without prior notice to Users where:

• it performs regular or emergency inspection or maintenance of the Service’s systems;
• computers, communication lines or the like stop due to an accident;
• force majeure such as fire, power failure, natural disaster, epidemic, infectious disease, or intervention or request by government authorities (including local governments) makes operation impossible;
• an External Service suffers trouble, interruption or suspension, stops working with the Service, or changes its specifications;
• the Company otherwise reasonably judges suspension or interruption necessary.

The Company may end provision of the Service at its reasonable discretion, with prior notice to Users.

The Company is not liable for damage suffered by Users from measures under this Article except in cases of its wilful misconduct or gross negligence.

Article 12 Equipment

• Users prepare and maintain, at their own cost and responsibility, the computers, software, other equipment, communication lines and other environment needed to use the Service.
• Users take security measures suited to their own environment — preventing virus infection, unauthorised access and information leaks — at their own cost and responsibility.
• When installing software on their computers to start or continue using the Service, Users take sufficient care to avoid loss or alteration of their information or failure or damage to their equipment.

Article 13 Ownership of rights

• All ownership and Intellectual Property Rights in the App and the Service belong to the Company or its licensors. The licence to use the Service under the Terms does not transfer or license any Intellectual Property Rights of the Company or its licensors except as expressly stated in the Terms.
• The Company may freely use opinions, requests and other feedback Users provide about the Service, to improve the Service or otherwise, without payment to the User.

Article 14 Display of names and logos

• Where a User is a corporation or other organisation, the Company may display the User’s name and logo on its website, sales materials, press releases and other promotional materials as a customer of the Service, and the User grants this permission. Such display is limited to showing the name and logo and does not imply an endorsement or other statement by the User.
• A User may at any time refuse such display, or request that it stop, by the method the Company prescribes; the Company will stop the display within a reasonable period after the request.
• The Company uses a User’s logo in the form and colours the User provides or publishes and does not alter it.

Article 15 Cancellation of registration

• The Company may suspend a User’s use of the Service or cancel their registration without prior notice or demand where the User:

• breaches any provision of the Terms;
• is found to have false Registration Information;
• uses or attempts to use the Service for a purpose or in a manner likely to cause damage to the Company, other Users, External Providers or other third parties;
• can no longer receive an External Service or its integration because of a breach of External Terms or for other reasons;
• obstructs the operation of the Service by any means;
• suspends payments or becomes insolvent, or is the subject of a petition for bankruptcy, civil rehabilitation, corporate reorganisation, special liquidation or similar proceedings;
• is the subject of a petition for attachment, provisional attachment, provisional disposition, compulsory execution or auction;
• receives a disposition for delinquent taxes;
• falls under any item of Article 3, paragraph 5;
• is otherwise reasonably judged by the Company to be unsuitable as a User.

In any of the above cases the User forfeits the benefit of time for all debts owed to the Company and must pay them immediately.

A User may cancel their registration by notifying the Company by its prescribed method.

The Company is not liable for damage suffered by Users from acts under this Article except in cases of its wilful misconduct or gross negligence.

Article 16 User Data after termination

• After a Usage Agreement ends, the Company may delete the User Data once 30 days have passed from the end date. Users export the User Data they need, using the Service’s functions, before the agreement ends.
• Notwithstanding the preceding paragraph, the Company may retain part of the User Data to meet legal obligations, or for the reasonable period technically required to delete it from backups.

Article 17 Disclaimer and limitation of liability

• The Service is provided as is. The Company makes no warranty of any kind about the Service, including fitness for a particular purpose, commercial usefulness, completeness, continuity or the accuracy of output of AI Features.
• Even where a User obtains information about the Service, the App, other Users or any other matter from the Company directly or indirectly, the Company gives no warranty beyond what the Terms state.
• The Service may integrate with External Services, but such integration is not guaranteed; the Company is not liable for problems with it except in cases of its wilful misconduct or gross negligence.
• Where the Service integrates with an External Service, the User observes the External Terms at their own cost and responsibility; the Company is not liable for disputes between the User and the External Provider arising from a breach, except in cases of its wilful misconduct or gross negligence.
• Transactions, communications and disputes between a User and other Users, External Providers or other third parties in connection with the Service or the App are handled and resolved at the User’s responsibility; the Company is not liable for them except in cases of its wilful misconduct or gross negligence.
• The Company is not liable to compensate damage suffered by Users in connection with the Service — including interruption, suspension, termination, unavailability or change of the Service, deletion or loss of User Data, cancellation of registration, loss of data or failure or damage of equipment through use of the Service — except in cases of its wilful misconduct or gross negligence.
• Where the Company is nonetheless liable to a User for damages under the Consumer Contract Act or other mandatory law or for any other reason, its liability, except in cases of its wilful misconduct or gross negligence, is capped at the total fees the User paid the Company in the 12 months immediately before the event that caused the damage (1,000 yen for Users on the free plan only).

Article 18 Users’ liability

• A User who causes damage to the Company by breaching the Terms or in connection with use of the Service must compensate the Company.
• A User who receives a complaint from, or has a dispute with, other Users, External Providers or other third parties in connection with the Service must notify the Company immediately, handle the complaint or dispute at their own cost and responsibility, and report its progress and outcome at the Company’s request.
• Where the Company receives a claim from other Users, External Providers or other third parties for infringement or other reasons in connection with a User’s use of the Service, the User must compensate the Company for any amount it is compelled to pay the third party.

Article 19 Confidentiality

• “Confidential Information” means all information about the Company’s technology, sales, business, finances, organisation or other matters that the User receives or learns from the Company in writing, orally, on recording media or otherwise in connection with the Usage Agreement or the Service, except information that (1) was already public or already known to the User when provided or learned; (2) became public after being provided or learned through no fault of the User; (3) was lawfully obtained from an authorised third party without a confidentiality obligation; (4) was developed independently without reference to Confidential Information; or (5) the Company confirmed in writing need not be kept confidential.
• Users use Confidential Information only for the purpose of using the Service and do not provide, disclose or leak it to third parties without the Company’s written consent.
• Notwithstanding the preceding paragraph, Users may disclose Confidential Information under an order, demand or request of law, a court or a government agency, provided they promptly notify the Company.
• At the Company’s request Users return or destroy, without delay and as instructed, Confidential Information and all documents, media and copies containing it.

Article 20 Personal information

• The Company handles Users’ personal information (as defined in Article 2, paragraph 1 of the Act on the Protection of Personal Information) in accordance with its separately posted Privacy Policy, and Users consent to such handling.
• Where User Data contains third parties’ personal information, the User carries out, at their own responsibility, the procedures required under the Act on the Protection of Personal Information and other laws for handling it on the Service.

Article 21 Term

The Usage Agreement takes effect on the day it is formed and remains in force until the earlier of the day the User’s registration is cancelled or the day provision of the Service ends.

Article 22 Changes to the Terms

• The Company may freely change the content of the Service.
• The Company may change the Terms (including rules, price lists and other provisions about the Service posted in the App or on its website). When doing so it announces the content and effective date of the change by its prescribed method before that date. A User who uses the Service after the announced effective date, or who does not cancel registration within the period the Company sets, is deemed to have agreed to the change.

Article 23 Communications and notices

Enquiries and other communications or notices from Users to the Company, and notices of changes to the Terms and other communications or notices from the Company to Users, are made by the method the Company prescribes (including email to the registered address and display in the App).

• Users may not assign, transfer, pledge or otherwise dispose of their position under the Usage Agreement or their rights or obligations under the Terms to third parties without the Company’s prior written consent.
• If the Company transfers the business of the Service to a third party (by business transfer, company split or otherwise), it may transfer its position under the Usage Agreement, its rights and obligations under the Terms, and Users’ Registration Information and other customer information to the transferee, and Users consent to this in advance.

Article 25 Entire agreement

The Terms constitute the entire agreement between the Company and the User on the matters they cover and prevail over any prior agreements, representations or understandings on those matters, whether oral or written.

Article 26 Severability

If any provision of the Terms or part of one is held invalid or unenforceable under the Consumer Contract Act or other laws, the remaining provisions and the remainder of the affected provision remain in full force, and the Company and the User will endeavour to amend the invalid or unenforceable provision or part as needed to make it lawful and enforceable and to secure its intent and a legally and economically equivalent effect.
