Legal

Terms of use

Last updated 25 October 2026

These terms cover this website and the kwant software you download from it. In short: kwant is free, you run it yourself, and you are responsible for what it does with your accounts.

License

kwant is open source under the GNU Affero General Public License v3.0 (AGPL-3.0). You can use, copy, change and share it for free, for any purpose. If you change kwant and let others use it over a network, you must offer them your changed source code under the same license.

If you want to use kwant without those conditions, for example to sell it, host it or build it into your own product without publishing your changes, you can ask for a commercial license at [email protected]. Versions published before the switch, including mac-v0.1.0, stay under MIT OR Apache-2.0. If anything in these terms conflicts with the license, the license wins for the software.

Provided as is

kwant is provided "as is", without warranty of any kind, as the license says. We don't promise that it works for your purpose, is free of bugs or keeps your data safe. To the extent the law allows, we are not liable for any damage from using it, including lost data, lost profits or costs you run up with other services. Nothing here limits liability that the law doesn't allow us to limit, such as for intent or gross negligence.

You run it, you're in charge

  • No hosted service. We don't run kwant for you and don't offer accounts, support contracts or uptime. kwant runs on your own computer or server.
  • Your accounts and keys. You bring your own AI accounts and API keys (Anthropic, OpenAI, xAI, Google, OpenRouter and others) and must follow those providers' terms and usage policies. Keep your keys and your kwant access token secret.
  • What your bots do. Bots act with the accounts, files, browser and tools you give them. You are responsible for what they do, including messages they send, purchases, changes to files and websites, and anything they post.
  • Approvals. kwant can ask before risky actions, but you choose the approval mode and you decide what to approve. Turning approvals down or off is your choice and your risk.
  • Costs. Model providers and other services may charge you for what your bots use. kwant's cost figures are estimates. Check your providers' billing and set limits there.
  • Other people's data. If you run kwant for others or let bots handle other people's personal data, you are responsible for doing that lawfully, including under the GDPR.

Mac app

The Mac app is signed ad hoc and not notarized by Apple, so macOS warns you the first time you open it. Opening it anyway is your decision. You can check the code and build it yourself from apps/mac.

Security issues

Please report vulnerabilities privately as described in SECURITY.md, not in a public issue.

Trademarks

kwant is an independent project. It is not affiliated with, endorsed by or sponsored by Anthropic, OpenAI, xAI, Google or Apple. Claude, ChatGPT, Codex, Grok, Gemini, macOS and other names belong to their owners and are used here only to say what kwant works with.

Law

These terms are governed by the law of Slovenia. If you are a consumer in the EU, you keep the protection of the mandatory rules of the country where you live. We may update these terms; the date at the top shows the last change.
