Terms of Service

Effective date: October 29, 2026

These Terms of Service ("Terms") are an agreement between you and Feiyu Liu, the independent developer who operates Timo ("we", "us"). They cover the Timo mobile app, the Timo desktop app and command-line tool, and the Timo sync service (together, "Timo"). By creating an account or using Timo, you agree to these Terms and acknowledge our Privacy Policy. If you do not agree, do not use Timo.

The English version of these Terms is the authoritative version. A Chinese translation is provided for convenience.

1. What Timo does

Timo lets you follow, approve and send instructions to AI coding agents, such as Claude Code or Codex, that run on your own computer, and keeps your sessions in sync between your computer and your phone.

Timo does not provide AI models. To use an agent, you need your own account and, where applicable, a subscription or API access with that agent's provider (for example Anthropic or OpenAI). Your use of those agents is governed by their providers' terms, and any fees they charge are between you and them.

2. Your account

You must be at least 13 years old, or the minimum age of digital consent in your country if higher, and able to form a binding contract.
Provide accurate information and keep your password and devices secure. You are responsible for activity under your account.
Tell us promptly at liufeiyu135@gmail.com if you believe your account has been compromised.
You can delete your account at any time in the app. Deletion is described in our Privacy Policy.

3. Your computer, your agents, your responsibility

AI agents can read and change files, run commands, install software and make network requests on your computer. Through Timo, you can start sessions, send instructions and approve actions remotely. You understand and agree that:

you are responsible for the instructions you send, the actions you approve, and the permissions and settings you give your agents;
agents can make mistakes, and their output may be incorrect, insecure or harmful; review it before relying on it;
you should keep backups and use version control for anything you care about;
you are responsible for any costs your agents incur with their providers;
you must have the right to use the computers, code and data you connect to Timo.

4. Your content

You keep all rights to the messages, code, files and other content you send or synchronize through Timo ("Your Content"). You grant us a limited license to store, transmit and process Your Content only as needed to operate Timo for you, as described in our Privacy Policy. This license ends when Your Content is deleted from our service.

5. Acceptable use

You must not use Timo to:

break any law or infringe anyone's rights;
access computers, accounts or data without authorization;
distribute malware or attack, disrupt or overload Timo or any other service;
circumvent Timo's security, usage limits or access controls, or access the service other than through the Timo apps and tools or interfaces we provide;
violate the terms of the AI providers whose agents you run;
resell or provide Timo to others as a service without our written permission.

We may suspend or terminate accounts that violate these Terms or put the service or other users at risk.

6. Paid features

Timo may offer paid features or subscriptions. If we do:

purchases in the iOS app are made through Apple's App Store and are subject to Apple's terms; Apple processes the payment;
subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before the period ends; you can manage or cancel them in your Apple account settings;
the price, period and features are shown before you buy; if we change a subscription price, you will be told in advance as Apple requires;
refunds are handled by Apple under its policies.

7. Open-source software

Parts of Timo are based on open-source software, including Happy, which is licensed under the MIT License. Open-source components are governed by their own licenses, which are available in the app and in the source code. Nothing in these Terms limits your rights under those licenses.

8. Changes and availability

Timo is under active development. We may add, change or remove features, and we may suspend or discontinue the service. We will try to give reasonable notice of significant changes or of shutting down the service. We do not guarantee that Timo will always be available, uninterrupted or free of errors, or that data will never be lost; keep your own copies of anything important.

9. Termination

You may stop using Timo and delete your account at any time. We may suspend or end your access if you breach these Terms, if required by law, or if we discontinue the service. Sections 3, 4 (until Your Content is deleted), 10, 11, 12 and 14 survive termination.

10. Disclaimers

To the maximum extent permitted by law, Timo is provided "as is" and "as available", without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, and accuracy. We are not responsible for the behavior or output of AI agents, for the services of AI providers, or for actions you approve through Timo.

11. Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, profits, revenue or business, arising from or related to your use of Timo. Our total liability for all claims relating to Timo will not exceed the greater of the amount you paid us for Timo in the 12 months before the claim or USD 50.

Some jurisdictions do not allow these exclusions or limits. In that case they apply only to the extent permitted, and nothing in these Terms limits liability that cannot be limited by law, or your statutory rights as a consumer.

12. Indemnity

To the extent permitted by law, you agree to indemnify us against claims, losses and expenses, including reasonable legal fees, that arise from your misuse of Timo, Your Content, or your breach of these Terms.

13. Apple App Store terms

If you downloaded Timo from Apple's App Store, the following also applies:

These Terms are between you and us, not Apple. We, not Apple, are solely responsible for Timo and its content.
Your license to use the app is limited to use on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
Apple has no obligation to provide maintenance or support for the app.
If the app fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app.
We, not Apple, are responsible for addressing any claims by you or a third party relating to the app, including product liability claims, claims that the app fails to conform to legal or regulatory requirements, and claims under consumer protection, privacy or similar laws.
If a third party claims that the app or your use of it infringes its intellectual property rights, we, not Apple, are responsible for investigating, defending, settling and discharging that claim.
You represent that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

14. General

Governing law. These Terms are governed by the laws of the jurisdiction where the operator resides, without regard to its conflict-of-law rules. If you are a consumer, this does not deprive you of the protection of the mandatory laws of your country of residence, and you may bring claims in your local courts.
Changes. We may update these Terms. We will post the updated version on this page with a new effective date and notify you in the app or by email of material changes before they take effect. If you continue to use Timo after that, you accept the updated Terms.
Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and us about Timo. If any provision is found unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver.
Assignment. You may not transfer your rights under these Terms without our consent. We may transfer ours to a successor operator of Timo.
