Hakutaku Terms of Service

The Portuguese version prevails.

1. Parties and acceptance

1.1. These Terms govern the contract between Hakutaku Soluções em Gestão de Dados Ltda., CNPJ 57.982.157/0001-87, registered at Rua Engenheiro Bianor, 137, Apto 301, Butantã, São Paulo/SP, CEP 05502-010 ("Hakutaku") and the individual or legal entity that creates an account or subscribes to the platform ("Customer" or "you").

1.2. By creating an account or subscribing to a plan, you confirm you have read and accepted these Terms, the Terms of Use and the Privacy Policy, made available before purchase. We record the accepted version and the date of acceptance.

1.3. If you accept on behalf of an organization, you confirm you have authority to bind it.

1.4. The platform is intended for people aged 18 and over.

2. The service

2.1. Hakutaku is a knowledge platform with an AI assistant: it organizes documents, e-mail, calendars, meetings and messages you connect or send, builds a "brain" (search and knowledge graph) and answers, suggests and performs tasks at your request, including by voice, messaging channels, automations and a cloud browser.

2.2. Features may be added, changed or discontinued to improve the service. If a change materially reduces an essential feature of a paid plan in force, we will give reasonable advance notice and you may cancel with a pro-rata refund of the unused period.

2.3. The service depends on third-party providers (cloud, AI models, apps you connect). We aim for high availability but do not guarantee uninterrupted operation; scheduled maintenance will be announced when possible.

3. Account and security

3.1. You must provide accurate information and keep your credentials confidential. Tell us immediately at haku@hakutaku.ai if you suspect misuse.

3.2. In organizations, administrators define roles, permissions and content visibility; the organization Customer is responsible for managing its members.

4. Plans, payment and cancellation

4.1. Prices, limits (including AI usage) and conditions of each plan are shown before purchase. AI usage costs may be passed through according to the plan's price table.

4.2. Paid plans renew automatically at the end of each period, at the current price, until cancelled. Price changes will be announced at least 30 days in advance and you may cancel before they take effect.

4.3. Right of withdrawal: if you are a consumer and purchased online, you may withdraw within 7 (seven) days of purchase with a full refund (Consumer Protection Code art. 49).

4.4. You may cancel at any time in settings or at haku@hakutaku.ai. Access continues until the end of the paid period, except under 4.3.

4.5. Billing is handled by a third-party payment processor. If payment fails, we may suspend paid features after notice.

5. Customer content

5.1. You keep all rights to the content you send or connect and to the results generated for you.

5.2. You grant us a limited, non-exclusive licence, for the term of the contract, to store, process, transmit to our processors and display the content solely to provide and protect the service, as described in the Privacy Policy. We do not use your content to train our own models and we do not sell it.

5.3. You are responsible for having a legal basis and rights for the content you bring to the platform, including third parties' personal data.

6. Data protection

6.1. Personal data processing follows the Privacy Policy and the LGPD.

6.2. For organization Customers, Hakutaku acts as processor of work content under the Data Processing Agreement (DPA), which forms part of these Terms.

7. Artificial intelligence

7.1. Answers, summaries, transcripts, graph extractions and suggestions are generated automatically and may be inaccurate, incomplete or out of date. Check relevant information before deciding or acting.

7.2. Outward actions (sending messages, posting, changing or deleting data in connected apps) are performed only at your request or with your approval, or by automations you set up. Review what you approve.

7.3. We do not use member content to train AI models, and we require our providers not to either.

8. Hakutaku's intellectual property

The platform, software, trademarks, design and documentation belong to Hakutaku or its licensors. We grant you a personal, non-exclusive, non-transferable licence to use the platform during the contract, under these Terms and the Terms of Use.

9. Liability

9.1. Nothing in these Terms excludes or limits rights the law grants consumers, including Hakutaku's liability for service defects (Consumer Protection Code arts. 14, 25 and 51) and for damages arising from LGPD violations (arts. 42 to 45).

9.2. Hakutaku is not liable for damage caused exclusively by the user or a third party (Consumer Protection Code art. 14 §3 II), for example: using AI answers without the check described in 7.1, unlawful content sent by the user, or failures of third-party apps you connected that are not under our control.

9.3. Business Customers that are not consumers (or, for business consumers, in justified situations under art. 51 I of the Consumer Protection Code): Hakutaku's total liability per contract year is limited to the amount paid by the Customer in the 12 months before the event, excluding lost profits and indirect damages. This cap does not apply to breaches of confidentiality or data protection, wilful misconduct or gross negligence, or obligations the law does not allow to be limited.

10. Suspension and termination

10.1. We may suspend or terminate access, with prior notice where possible, for breach of these Terms or the Terms of Use, risk to security or third parties, legal order, or non-payment. In serious or urgent cases suspension may be immediate, with an explanation afterwards.

10.2. You may close your account at any time.

10.3. On termination, you may export your data for 30 days, after which we delete it under the Privacy Policy, except what the law requires us to keep.

11. Changes to these Terms

We may change these Terms to reflect changes in the service or the law. Material changes will be announced prominently at least 30 days in advance. If you disagree, you may cancel before they take effect, without penalty. Changes do not affect amounts already paid.

12. General

12.1. If any clause is held invalid, the others remain in force.

12.2. Tolerating a breach is not a waiver.

12.3. Notices are sent to the account e-mail or within the platform. Contact us at haku@hakutaku.ai; legal matters at haku@hakutaku.ai.

13. Governing law and forum

13.1. These Terms are governed by the laws of the Federative Republic of Brazil.

13.2. If you are a consumer, you may sue in the courts of your domicile (Consumer Protection Code art. 101 I). For Customers that are not consumers, the courts of São Paulo/SP are chosen. Nothing here prevents seeking an amicable solution at haku@hakutaku.ai or on public platforms such as consumidor.gov.br.
