Terms of Service

Effective: July 14, 2026 · applies to opencoworker.app, the downloadable app, and OpenCoworker Cloud · supersedes the June 11, 2026 version

These terms are a contract between you and the maintainers of the Open Coworker project (“Open Coworker,” “we,” “us”). They cover this website, the pre-built copies of the app we distribute, and the optional OpenCoworker Cloud account service (together, the “Services”). The Open Coworker source code is open source and is governed solely by its own license — currently the MIT License — not by these terms. By using the Services, you agree to what follows.

01The software is open source — and free

Open Coworker is free software released under the MIT License. You may use, copy, modify, and redistribute the source code under that license without reference to these terms. These terms only add conditions for the website and the convenience builds (installers) we publish; they never restrict rights the open-source license grants you.

We don’t charge for the app, and there are no subscriptions or in-app purchases. The app works without an account; signing in to the optional, free OpenCoworker Cloud adds managed connections to third-party services (section 03a). If anything ever costs money, we’ll say so clearly first.

02You bring your own model provider

Open Coworker ships without an AI model and includes no model credits. The app will not work until you connect a model yourself. To use it, you must obtain your own API key directly from a model provider — such as OpenAI, Anthropic, or Google — and pay that provider for your usage under your own agreement with them, or run a local model on your own hardware (for example, with Ollama). That means:

  • Your use of any model provider is governed by your agreement with that provider, including their usage policies and pricing. Charges they bill you are between you and them.
  • Content you send through the app to a provider is handled under that provider’s privacy and data-retention practices, which we don’t control.
  • We are not responsible for the availability, accuracy, or behavior of any third-party model or service, and you release us from claims arising out of your use of them.
  • You are responsible for keeping your API keys secure. Keys you enter are stored locally on your machine.

03The app acts on your machine, at your direction

Open Coworker is an agent: at your instruction it can read and edit files on your computer, run commands, and — when you connect them — send messages and emails through your own accounts (for example Slack, Telegram, or email). You are the operator. That means:

  • You are responsible for the tasks you delegate and for reviewing what the agent does, especially actions that are hard to undo — sending messages, deleting or overwriting files, or anything involving money or credentials.
  • Anything the app sends or changes through your connected accounts is treated as done by you, under your agreements with those services.
  • Keep backups of data you care about. Agents make mistakes.

03aOpenCoworker Cloud and connected services

Signing in to OpenCoworker Cloud is optional and free. It provides managed connections: one-click sign-in to third-party services (such as Google, Slack, GitHub, or Microsoft) whose access tokens are delivered to and stored on your device. Our servers complete the sign-in handshake and relay inbound events; they do not store your tokens or your content — see the Privacy Policy for exactly what is and isn’t stored. Additionally:

  • Your use of each connected service remains governed by that service’s terms, and you must have the right to connect the accounts you connect.
  • We may suspend accounts or connections that abuse the Services (for example, spam sent through connectors).
  • You can disconnect any service, or ask us to delete your Cloud account, at any time.

04AI output can be wrong

Output generated by AI models may be inaccurate, incomplete, outdated, or biased, and may resemble other people’s content. Don’t rely on it for consequential decisions — legal, medical, financial, or safety-related — without independent verification by a qualified human. As between you and us, you own your input and, to the extent we hold any rights in it, the output you generate; you are responsible for how you use both.

05Acceptable use

When using the Services, you agree not to:

  • violate any applicable law, or use the app to harm others or their systems;
  • infringe anyone’s intellectual-property, privacy, or publicity rights;
  • misrepresent AI-generated output as human-created where that matters to the recipient;
  • attack, overload, or attempt to disrupt this website or our distribution infrastructure;
  • use the Services to develop, train, or operate systems in violation of your model provider’s terms.

06Privacy

The app is local-first and collects no telemetry. Your sessions, files, and the agent’s memory stay on your machine, except for what you choose to send to your model provider or through connectors you enable. What the optional OpenCoworker Cloud account stores, how connected services (including Google user data) are handled, and how to delete everything are described in our Privacy Policy, which is part of these terms.

07Changes to the Services and to these terms

Open Coworker is young software that changes quickly. We may modify, pause, or discontinue any part of the Services at any time without liability to you — though the open-source code, and your local copy of the app, remain yours to use under the MIT License regardless.

We may also update these terms. When we do, we’ll post the new version here with a new effective date. If you keep using the Services after a change, that means you accept it; if you don’t agree, stop using the Services.

08Termination

You can stop using the Services at any time. We may suspend or block access to the website or our distribution channels (for example, for abuse). Sections 02–05 and 09–11 survive termination. Your rights under the MIT License are independent of these terms and are not affected.

09No warranty

THE SERVICES, THE APP, AND ALL CONTENT ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED OR ERROR-FREE OPERATION. YOU USE THE SERVICES AT YOUR OWN RISK.

10Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, DATA, OR GOODWILL, ARISING FROM OR RELATED TO THE SERVICES OR THE APP — INCLUDING ACTIONS THE AGENT TAKES ON YOUR MACHINE OR THROUGH YOUR CONNECTED ACCOUNTS — EVEN IF ADVISED OF THE POSSIBILITY. OUR TOTAL LIABILITY FOR ALL CLAIMS WILL NOT EXCEED ONE HUNDRED U.S. DOLLARS (US$100) OR THE AMOUNT YOU PAID US IN THE PAST TWELVE MONTHS, WHICHEVER IS GREATER. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO PARTS OF THIS SECTION MAY NOT APPLY TO YOU.

11Indemnity, governing law, and the rest

You agree to indemnify us against claims arising from your use of the Services in violation of these terms or of applicable law, including reasonable attorneys’ fees.

These terms are governed by the laws of the State of California, USA, without regard to conflict-of-laws rules, and disputes will be brought in the state or federal courts located in California. If any provision is found unenforceable, the rest remains in effect. Our not enforcing a provision is not a waiver. These terms are the entire agreement between you and us about the Services, and you may not assign them without our consent.
