Terms of Service

Last updated: June 20, 2026

These Terms of Service ("Terms") are a legal agreement between you and Nexight Technology (HK) Limited — a private company limited by shares incorporated in Hong Kong under the Companies Ordinance (Cap. 622), Company No. 80177350 ("we," "us," or "our") — and govern your use of Tutti's hosted services — including the Tutti app catalog and app runtimes, software-update services, the website at tutti.sh, and Tutti · Cloud if and when it becomes available (collectively, the "Services").

Please read these Terms together with our Privacy Policy, which is incorporated by reference.

By using the Services, you agree to these Terms. If you do not agree, do not use the Services. The Services are for users who are at least 18 years old.

1. The open-source app comes first

Tutti · Local — the desktop application, command-line tools, and local daemon — is free and open-source software licensed under the Apache License, Version 2.0. Your rights to use, copy, modify, and distribute that software are governed by that license (see the LICENSE file in our repository), not by these Terms. Nothing in these Terms limits your rights under the Apache-2.0 license.

These Terms apply when you use our hosted services alongside the app (for example, downloading apps from our catalog or receiving updates), and to your use of our brand (section 3).

2. The Services and your Agents

Tutti lets you run AI Agents that operate in a shared workspace. With Tutti · Local, those Agents run on your own computer, using AI model providers you choose and configure with your own credentials.

You are responsible for your Agents. This includes the code they write, the commands they run, the files they read or change, and the external tools and APIs they call on your machine. You are responsible for reviewing and approving Agent actions where Tutti asks for your approval, and for ensuring your use of any AI model provider complies with that provider's terms.

3. Brand and intellectual property

The Services (other than the open-source app), including the website, the app catalog interface, and our content, are owned by us or our licensors. The "Tutti" name, logos, and brand are our trademarks.

  • The Apache-2.0 license for Tutti · Local does not grant trademark rights (see Apache-2.0 §6). You may not use the Tutti name or logos to imply endorsement, or in a way that is confusing or disparaging, without our prior written permission. Nominative references ("works with Tutti," "a fork of Tutti") are fine.
  • We grant you a limited, non-exclusive, revocable right to access and use the hosted Services for their intended purpose, including for your own internal or business use.

4. Acceptable use

You agree not to:

  • use the Services in violation of any law, or to infringe others' rights;
  • interfere with, overload, or disrupt the Services or their infrastructure, or attempt to gain unauthorized access to them;
  • misuse the app catalog or updates to distribute malware or unlawful content; or
  • resell, sublicense, or provide the hosted Services themselves to third parties as your own service, or use them to build a competing hosted service.

Running AI Agents that you configure through Tutti — including automated and long-running Agents — is a core, permitted feature of the Services and is not a violation of any "no bots / no automation" expectation.

5. Apps in the catalog

The Tutti app catalog includes apps that may be published by us, by the community, or by you. Apps not published by us are provided by their respective authors. We do not guarantee, endorse, or assume responsibility for third-party apps, and your use of them may be subject to their own terms. We may remove apps from the catalog at our discretion.

6. Your content

You retain ownership of the content you create, including anything you may share into a Tutti · Cloud workspace if and when that service becomes available ("Your Content"). We do not claim ownership of Your Content.

You grant us only the limited rights we need to operate and provide the Services — for example, to store, transmit, and display Your Content to the teammates you share it with in a cloud workspace, and to make backups. This license exists only to run the Services for you and ends when you delete Your Content or your account, except for residual backup copies and where retention is legally required. We do not sell Your Content and do not use the contents of your workspaces or Agent conversations for advertising or to train our own models.

You are responsible for Your Content and for having the rights to share it. We may remove content that violates these Terms or the law.

7. AI features — important disclaimers

Tutti's Services include AI features and Agents. You acknowledge that:

  • AI output can be wrong. Output may be inaccurate, incomplete, or inappropriate. You are responsible for reviewing it before relying on it, especially for actions that change files, run commands, or are otherwise hard to reverse.
  • Agents act on your instructions and your systems. You are responsible for the consequences of actions you allow an Agent to take on your computer or accounts.
  • Model providers are third parties. AI processing is performed by the providers you select, under their terms; we are not responsible for their output or availability.

8. Tutti · Cloud (not yet available)

Tutti · Cloud — an optional hosted service for collaborating with teammates across devices — is not yet available. When we make it available, it will require an account and may include paid plans. We will publish the terms that govern Tutti · Cloud (including any account, early-access, payment, and data-processing terms) and make them available to you before you can start using it.

9. Third-party services

The Services rely on or link to third parties (for example, your AI model providers, content-delivery and release infrastructure, and our analytics provider, as described in the Privacy Policy). We are not responsible for third-party services, and your use of them is governed by their terms.

10. Disclaimers

The Services are provided "as is" and "as available," without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Services will be uninterrupted, error-free, or secure. Some jurisdictions do not allow certain warranty exclusions, so some of the above may not apply to you.

11. Limitation of liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, revenue, data, or goodwill, arising out of or relating to the Services. Our total liability for any claim relating to the Services will not exceed the greater of (a) the amount you paid us for the Services in the 12 months before the claim, or (b) USD 100.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law (including, where applicable, liability for death or personal injury, fraud, or — under the laws of some jurisdictions — gross negligence or wilful misconduct). If you are a consumer, you keep the mandatory rights and protections of your country of residence, and these limits apply only to the extent permitted there.

12. Indemnification

To the extent permitted by law, you agree to indemnify and hold us harmless from claims and expenses arising out of your misuse of the Services, your violation of these Terms or the law, or your infringement of a third party's rights. This does not apply to the extent a claim arises from our own breach of these Terms.

13. Termination

You may stop using the Services at any time. We may suspend or terminate your access to the hosted Services if you materially breach these Terms or where necessary to protect the Services or other users. Termination of the hosted Services does not affect your rights to the open-source app under Apache-2.0. Sections that by their nature should survive (for example, sections 6, 7, 10, 11, 12, 14, and 15) survive termination.

14. Governing law and disputes

These Terms are governed by the laws of the Hong Kong Special Administrative Region of the People's Republic of China, without regard to its conflict-of-laws rules.

The parties will first try to resolve any dispute informally by contacting business@tutti.sh and negotiating in good faith for at least 30 days. If that fails, the dispute will be subject to the non-exclusive jurisdiction of the courts of the Hong Kong Special Administrative Region.

Consumers. If you use the Services as a consumer, nothing in this section deprives you of the right to bring proceedings in your country of residence or to rely on the mandatory consumer-protection laws that apply to you.

15. Changes to these Terms

We may update these Terms from time to time. When we make changes, we will update the "Last updated" date, and for material changes we will give reasonable advance notice (for example, in the app, on the website, or by email to Tutti · Cloud account holders). Material changes that affect paid plans or this section will not apply retroactively. Your continued use of the Services after a change takes effect means you accept the updated Terms; if you do not agree, stop using the hosted Services.

16. General

These Terms (with the Privacy Policy and any service-specific terms) are the entire agreement between you and us regarding the hosted Services. If any provision is held unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them to a successor in connection with a merger, acquisition, or sale of assets. We are not liable for delays or failures caused by events beyond our reasonable control.
