Terms of Service

Effective date: April 9, 2026

These terms of service (“Terms”) govern your use of the services provided by Santuri LLC (“Santuri,” “we,” “us,” or “our”), including the website at santuri.io and the managed AI personal assistant service. By using our service, you agree to these Terms.

1. Service Description

Santuri provides a managed AI personal assistant that handles tasks such as email management, calendar scheduling, task tracking, and other productivity workflows on your behalf. The assistant operates via Telegram and integrates with third-party services you authorize.

The service includes an onboarding session, ongoing AI assistant operation, and support. The specific capabilities and features of the service may change over time as we improve and update our technology.

2. Eligibility

You must be at least 18 years old and capable of entering into a binding agreement to use our service. By subscribing, you represent and warrant that you meet these requirements and that all information you provide is accurate and complete.

3. Account and Access

You are responsible for maintaining the confidentiality and security of your account credentials and any third-party service access you grant to your assistant. You are fully responsible for all activities that occur under your account, whether or not authorized by you.

You agree to notify us immediately at [email protected] if you suspect unauthorized access to your account. We are not liable for any loss or damage arising from your failure to maintain the security of your account.

4. Acceptable Use

You agree not to use the service to:

— Violate any applicable local, state, national, or international law or regulation.

— Send spam, phishing messages, or other unsolicited or harassing communications through your assistant.

— Process, store, or transmit material that infringes on the intellectual property rights of any third party.

— Attempt to access systems, data, or accounts you are not authorized to access.

— Interfere with, disrupt, or place an undue burden on the service or its infrastructure.

— Use the service for any illegal, fraudulent, or harmful purpose.

— Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code or underlying algorithms of the service.

We reserve the right to suspend or terminate your access at our sole discretion, without prior notice or liability, if we believe you have violated these terms or if your use poses a risk to us, our service, or other users.

5. Subscription and Payment

The service is billed monthly at the rate displayed on our website at the time of subscription. Payments are processed through our third-party payment provider. You authorize us to charge your payment method on a recurring basis until you cancel.

We reserve the right to change our pricing at any time. We will provide you with at least 30 days’ notice before any price change takes effect. Your continued use of the service after the price change constitutes your agreement to pay the updated amount.

You may cancel your subscription at any time by contacting us at [email protected]. Cancellation takes effect at the end of the current billing period. We do not offer refunds for partial billing periods, and all fees paid are non-refundable except as expressly set forth in these Terms or as required by applicable law.

6. Service Availability

We reserve the right to modify, suspend, or discontinue the service (or any part thereof) at any time, with or without notice, and without liability to you. We do not guarantee that the service will be available at all times or that it will be uninterrupted, timely, secure, or error-free.

We perform routine maintenance and backups but assume no liability or responsibility for any loss or corruption of data. You acknowledge that it is your responsibility to maintain appropriate backups of your data.

7. AI-Generated Output and Autonomous Actions

THE SERVICE USES ARTIFICIAL INTELLIGENCE AND MACHINE LEARNING MODELS TO GENERATE RESPONSES AND TAKE ACTIONS ON YOUR BEHALF. YOU ACKNOWLEDGE AND AGREE THAT:

— AI-generated output may be inaccurate, incomplete, misleading, or inappropriate. You must independently verify any information or actions before relying on them.

— The assistant may take actions on connected third-party services (such as sending emails, scheduling events, or modifying data) based on its interpretation of your instructions. You are solely responsible for reviewing and approving these actions.

— Santuri does not guarantee the accuracy, reliability, completeness, or timeliness of any AI-generated output or action.

— Santuri is not liable for any decisions you make, actions you take, or consequences that arise from relying on AI-generated output, including but not limited to financial loss, reputational harm, missed communications, or data loss.

— AI models are provided by third-party providers and may change, degrade, or become unavailable without notice. We are not responsible for changes in the quality, availability, or behavior of underlying AI models.
