Terms of Service

Last updated: 2026-10-01

These Terms of Service ("Terms") govern access to and use of OneChat at https://stg.onechat.tabsystems.tech (the "Service"), provided by Tab Systems Mongolia LLC, Pearl Tower A-1203, 3rd khoroo, Chingeltei district, Ulaanbaatar, Mongolia ("we", "us"). By using the Service you agree to these Terms. If you use it on behalf of a business, you confirm that you may bind that business to them.

1. The Service

OneChat brings a business's messaging channels into one inbox, lets the business set up AI assistants that answer its customers, and lets its staff take over any conversation. Features may change as we improve the Service.

2. Accounts

  • Accounts are created for a business ("Customer") by us or by the Customer's administrators. Self-registration is not available.
  • You are responsible for keeping your password and API keys secret and for everything done with your account. Tell us straight away at info@tabsolution.jp if you think your account has been misused.
  • Administrators of a Customer are responsible for the accounts they create and remove.

3. Your responsibilities

You agree to:

  • Use the Service only for lawful purposes and in line with these Terms.
  • Follow the terms of every channel and service you connect, including those of Meta, Google, LINE, Discord, Chatwork and Viber, and of the AI model providers you choose.
  • Have a lawful basis, and give any notices required by law, for the personal data of the people who message you through the Service.
  • Make sure the instructions and knowledge you give your AI assistants are accurate and lawful.

4. Acceptable use

You must not:

  • Send spam or messages the recipient has not agreed to receive.
  • Use the Service for content or activity that is illegal, fraudulent, harassing or that infringes the rights of others.
  • Try to gain access to data or accounts that are not yours, or to test, probe or disrupt the Service's security.
  • Reverse engineer the Service, or resell it without our written agreement.
  • Use the Service to build a competing product.

5. AI assistants

AI assistants generate replies automatically and can make mistakes. You are responsible for how you configure and use them, and for reviewing their replies where accuracy matters. The Service lets you take over a conversation at any time. Do not rely on an AI reply as professional, legal, medical or financial advice.

6. Third-party services

The Service connects to services run by others, such as messaging channels, Google and AI model providers. Your use of them is governed by their own terms. We are not responsible for their availability, changes or content.

7. Your data

You keep all rights to the content and data you and your customers put into the Service ("Customer Data"). You give us permission to host, process and transmit Customer Data only as needed to provide and secure the Service. Our Privacy Policy explains how we handle personal data.

8. Fees

Fees, if any, are set out in your agreement or order with us. Unless that agreement says otherwise, fees are not refundable.

9. Suspension and termination

  • We may suspend access if you breach these Terms, if your use puts the Service or others at risk, or if the law requires it. Where reasonable, we will tell you first.
  • You may stop using the Service at any time. Either side may end the agreement as set out in your agreement with us.
  • After termination, Customer Data is deleted in line with our Privacy Policy, unless the law requires us to keep it.

10. Our intellectual property

The Service, including its software and design, belongs to us or our licensors. These Terms do not give you any rights to it beyond using the Service as allowed here.

11. Disclaimers

The Service is provided "as is" and "as available". To the extent the law allows, we make no warranties, express or implied, including that the Service will be uninterrupted or error-free, or that AI replies will be accurate.

12. Limitation of liability

To the extent the law allows, we are not liable for indirect, incidental, special or consequential damages, or for lost profits, revenue or data. Our total liability for any claim relating to the Service is limited to the amount you paid us for the Service in the 12 months before the claim.

13. Governing law

These Terms are governed by the laws of Mongolia.

14. Changes to these Terms

We may update these Terms. The date at the top of the page shows when they last changed. If a change is significant, we will tell Customers before it takes effect. Continuing to use the Service after a change means you accept it.
