Terms of Use

By creating a Zihin account, accessing the API, configuring a tenant, or using any platform feature, you ("Customer" or "Tenant") fully agree to these Terms of Use, the Privacy Policy, and the attached DPA (Data Processing Agreement), which together constitute the binding agreement between you and Zihin AI Inc. ("Zihin", "we").

If you act on behalf of a legal entity, you represent that you have the authority to bind that entity to these Terms.

If you do not agree with any provision of these Terms, you must not use the platform.

Zihin is a multi-tenant SaaS platform for building, orchestrating, and operating autonomous artificial intelligence agents, offering:

Zihin may update, modify, evolve, or discontinue features at any time, with reasonable prior notice to Customers in case of materially relevant changes.

Zihin operates a three-layer channel model:

3.1. Technology (SaaS subscription). The platform license is billed globally by Zihin AI Inc., in US dollars (USD), via Stripe, under the direct relationship between the Customer and Zihin AI Inc.

3.2. Professional services in Brazil. Implementation, consulting, customization, integration, training, and advanced support services, when contracted by Customers in Brazil, may be provided and billed by Aionz Integração Serviços e Tecnologia Ltda (CNPJ 52.400.922/0001-90), Zihin's official integration partner in Brazil, in Brazilian reais (BRL), under a specific commercial agreement between Customer and Aionz.

3.3. Professional services in other geographies and accredited partners. In other geographies, or alternatively in Brazil, professional services may be provided and billed by integration partners accredited by Zihin, under a specific commercial agreement between the Customer and the chosen integration partner. Zihin maintains a partner accreditation program and is not liable for services provided directly by partners to Customers, subject to its obligation of reasonable selection and supervision.

3.4. Independence of relationships. The platform subscription (item 3.1) is independent from the contracting of professional services (items 3.2 and 3.3). The Customer may subscribe to the platform only and operate with its own team, or combine the platform with services from Aionz or accredited partners.

4.1. To use the platform, the Customer must create a tenant and provide:

4.2. The Customer is responsible for:

4.3. Zihin may suspend or terminate accounts in cases of abuse, fraud, violation of these Terms, or risk to platform security.

5.1. The Customer agrees to:

5.2. Zihin may apply rate limits, credit limits, token quotas, or other restrictions according to the contracted plan.

5.3. Token Quota. Each subscription plan includes a monthly token quota. Tokens reset at the beginning of each billing cycle, do not accumulate, and expire at the end of the cycle. Consumption is tracked in real time on the dashboard. Alerts are sent at 80% and 90% usage.

6.1. When using the platform, the Customer submits texts, documents, instructions, structured data, database connections, integration configurations, and other content ("Customer Content") for processing.

6.2. Permissions granted to Zihin. The Customer authorizes Zihin to:

6.3. Use for AI training. Zihin does not use Customer Content to train its own AI models. When routing requests to third-party providers, Zihin uses, whenever available, the API settings that opt out of training by those providers. Each provider has its own data policies, which the Customer should review directly.

6.4. Connections to Customer databases and systems. When the Customer configures a connection to its own database or to third-party systems under its control, Zihin acts exclusively as Processor of such data, as detailed in the attached DPA. The Customer is the Controller of the data accessed or processed through those connections.

7.1. General principle. Zihin provides the technical platform for building and orchestrating autonomous agents. The Customer is fully responsible for the schemas, triggers, MCP servers, database connections, external API integrations, and other configurations established in its tenant, as well as for the actions performed by the agents in third-party systems as a result of those configurations.

7.2. Non-exhaustive examples of Customer responsibility. The Customer's responsibility includes:

7.3. Zihin's responsibility. Zihin is responsible exclusively for the technical operation of the orchestration platform, subject to the SLA (item 11) and the limitation of liability (item 14). Zihin is not liable for errors, omissions, inadequate decisions, or losses arising from the Customer's configurations or from actions performed by agents in third-party systems.

8.1. Inherent limitations. The Customer acknowledges that AI systems have inherent limitations, including the possibility of inaccurate, outdated, biased, hallucinated, or contextually inappropriate outputs. Zihin does not guarantee the accuracy, completeness, or suitability of outputs generated by AI models routed through the platform.

8.2. Sensitive decisions. The Customer is responsible for ensuring adequate human oversight for AI decisions with potential material impact, especially in medical, legal, financial, tax, human resources, security, or legal-compliance contexts. Zihin does not recommend or authorize the use of AI outputs as the sole basis for decisions in such contexts.

8.3. End-user transparency. When the Customer's agents interact with natural persons (end users), the Customer must clearly and noticeably inform that the interaction is with an AI system, in compliance with applicable transparency requirements (including, where applicable, Art. 50 of the EU AI Act and analogous regulations).

9.1. The Customer may not use Zihin to:

9.2. Violations may result in immediate account suspension, without prejudice to other applicable consequences.

10.1. Platform subscription. Charges are processed via Stripe by Zihin AI Inc. By subscribing, the Customer authorizes recurring charges, automatic renewal, and processing via the provided payment method. Prices and limits may change upon 14 days' notice.

10.2. Professional services. Services provided by Aionz (item 3.2) or accredited partners (item 3.3) are governed by specific commercial agreements entered into directly between the Customer and the respective provider.

10.3. Cancellation. The Customer may cancel the subscription at any time. Cancellation takes effect at the end of the current billing period. There is no partial refund for unused time within a cycle.

12.2. Window. Support is provided during Brazilian business hours (UTC-3), Monday through Friday, except Brazilian and US national holidays.

13.1. The Zihin platform, including its proprietary routing algorithms, APIs, source code, documentation, trademarks, and other assets, is the exclusive property of Zihin AI Inc.

13.2. The Customer fully retains ownership of its Customer Content. Nothing in these Terms transfers the Customer's intellectual property rights to Zihin.

13.3. AI-generated outputs are provided without warranty of originality or novelty. The Customer is responsible for verifying compliance with intellectual property laws applicable to its use.

14.1. To the maximum extent permitted by law, Zihin is not liable for:

14.2. Zihin's total aggregate liability to the Customer, in any event, shall not exceed the amount actually paid by the Customer in the 12 (twelve) months preceding the event giving rise to the claim.

The Customer agrees to indemnify and hold Zihin harmless from any claims, losses, damages, and costs (including reasonable attorneys' fees) arising from:

16.1. The Customer may terminate its account at any time. Zihin may terminate accounts in cases of abuse, fraud, violation of these Terms, default, or illegal use.

16.2. After termination, data is handled in accordance with the Privacy Policy and the DPA, including minimum retention required by law.

Zihin may modify these Terms at any time. Material changes will be communicated via e-mail or dashboard notification at least 14 days in advance. Continued use of the platform after the changes take effect constitutes acceptance.

18.1. Global terms (Zihin AI Inc.). These Terms, in the direct relationship between Customer and Zihin AI Inc., are governed by the laws of the State of Delaware, USA. Disputes shall be submitted to the competent courts of Delaware, unless the law applicable to the Customer requires a different forum.

18.2. Brazilian customers via Aionz. For professional services provided in Brazil by Aionz (item 3.2), Brazilian law (including LGPD, the Brazilian Internet Civil Framework, and the Consumer Protection Code, where applicable) prevails, with the courts of the Judicial District of Anápolis, State of Goiás, as the elected forum.

18.3. Customers via accredited partners. For services provided by accredited partners (item 3.3), the applicable law and forum are defined in the respective commercial agreement between Customer and partner.

19.1. These Terms, together with the Privacy Policy and the attached DPA, constitute the entire agreement between the parties regarding their subject matter.

19.2. The invalidity of any provision does not affect the remaining provisions.

19.3. One party's tolerance of the other party's non-compliance with any obligation does not imply waiver of the right to demand future compliance.
