1. Acceptance of terms
By using this website, or by downloading, installing, or running the Tangison Agent software, you agree to these terms. If you do not agree, do not use the software and do not browse this site. These terms form a binding agreement between you and Tangison, the company that owns and maintains the project. If you are using the software on behalf of an employer or a client, you represent that you have the authority to bind that organization to these terms. If you are under the age of 16, or if you are otherwise unable to enter into a binding contract under the laws of your jurisdiction, you may not use the software. We have kept these terms as short and as plain as we can. Nothing in them is designed to surprise you. If anything is unclear, ask before you deploy. Contact details are at the bottom of this page.
2. The software
Tangison Agent is open source software released under the MIT License. You can read the full license text in the repository at github.com/tangison/agent. The MIT License is one of the most permissive open source licenses in existence. It grants you broad rights to use, copy, modify, merge, publish, distribute, sublicense, and sell copies of the software. The only conditions are that you retain the copyright notice and the permission notice in all copies or substantial portions of the software. The license also states, in plain language, that the software is provided "as is" without warranty of any kind, and that the authors or copyright holders are not liable for any claim, damages, or other liability arising from the software. Those warranty and liability disclaimers are repeated in sections 6 and 7 below for convenience, but the MIT License is the controlling document. The parent company behind the project is described at tangison.com.
3. Usage
You may use Tangison Agent for any purpose permitted by the MIT License. That includes personal projects, commercial products, internal tooling, and redistribution. You are responsible for how you configure the agent, which skills you enable, and what data you allow it to access. The agent is powerful. It can read files, call external APIs, send messages on your behalf, and execute code. Think carefully before you grant it access to production systems or sensitive directories. You are also responsible for complying with the terms of service of any third-party API you connect to the agent. That includes OpenRouter for model access, Telegram and WhatsApp for messaging, Vercel for deploys, and any other service you wire up through a skill or an MCP connector. Their terms apply on top of these terms, not instead of them. If a third-party provider bans your account because of how you used the agent, that is between you and them.
4. Self-hosting responsibility
When you self-host Tangison Agent, you are the operator. That means you are responsible for securing your server, for rotating your API keys on a sane schedule, for backing up your data, and for complying with every law and regulation that applies to the people whose data flows through your deployment. Tangison is not liable for any damage caused by your deployment, including damage caused by a misconfigured skill, a leaked API key, an exposed port, or an agent that did something you did not expect. You should run the agent with the lowest privileges it needs to do its job, in a workspace you can rebuild from a script, with network policies that limit what it can reach. You should read every tool call in the audit log when something goes wrong. If you do not have the time or the expertise to operate a self-hosted agent safely, do not deploy it in production. The marketing site at tangison.com points to documentation that walks through hardening steps.
5. The marketing site
This website is provided as-is, as a courtesy, so that you can learn about the Tangison Agent project before you download it. We may change or remove content at any time, without notice. We may redesign pages, rewrite copy, remove sections, or take the entire site offline for maintenance. We may also discontinue the waitlist at any time, in which case the WhatsApp button on the homepage will stop working or will be removed. The waitlist is not a contract. Joining the waitlist does not guarantee you anything, including access to a hosted version of the software, a reply within a specific timeframe, or a feature you requested. The AI concierge widget on this site is a convenience. It answers questions about the project based on a model that can hallucinate. Do not rely on its answers for legal, medical, financial, or operational decisions. Read the source code and the documentation instead. If the widget gives you a wrong answer, we are not liable for what you do with it.
6. No warranty
The software and this website are provided "as is" without warranty of any kind, express or implied. The MIT License contains the complete warranty disclaimer and that disclaimer controls. To summarize it plainly: there is no warranty of merchantability, no warranty of fitness for a particular purpose, and no warranty of non-infringement. We do not promise that the software will meet your requirements, that it will run without errors, that it will be secure, or that it will be available at any given moment. We do not promise that the documentation is accurate, that the examples are safe to copy, or that the default configuration is right for your environment. Security vulnerabilities may exist. We fix them when we learn about them, and you can report one through the channels at the bottom of this page. But you deploy at your own risk. If you need a warranty, you need a commercial support contract, which we do not currently offer. Until then, the MIT License is the whole agreement on warranty.
7. Limitation of liability
To the maximum extent permitted by applicable law, Tangison and Tangi Iigonda shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the software or this website. That includes damages for loss of profits, loss of data, loss of business goodwill, business interruption, equipment failure, or any similar commercial damage or loss. Our total liability for any claim arising out of or relating to the software or the website, regardless of the form of the action, shall not exceed the amount you paid us for the software in the twelve months preceding the claim. Since the software is free and open source under the MIT License, that amount is typically zero. We are a small brand. We cannot absorb the liability that a large enterprise vendor can. If your use case cannot tolerate that limitation, you need different software or you need to negotiate a separate commercial agreement. Do not deploy Tangison Agent into a critical path unless you have accepted this limitation.
8. Indemnification
You agree to indemnify and hold harmless Tangison, Tangi Iigonda, and any contributor to the project against any claim, demand, suit, or proceeding that arises from your use of the software or your violation of these terms or any third-party right. That includes claims that your deployment of the agent infringed someone's intellectual property, violated a data-protection law, sent unsolicited messages through a messaging API in breach of that API's terms, or caused damage to a third party through a tool call the agent made on your behalf. You are responsible for the actions of your deployment. If a third party sues us because of something your agent did, you will cover the cost of defending the claim, including reasonable legal fees, and any damages or settlement amounts we are ordered to pay. We will give you notice of any such claim promptly and will cooperate with you in defending it. You will not settle a claim without our consent if the settlement would impose an obligation on us.
9. Changes to these terms
We may update these terms from time to time. When we do, we will change the "Last updated" date at the top of this page and, for material changes, post a notice on tangison.com. Continued use of the software or the website after a change takes effect constitutes your acceptance of the updated terms. If you do not agree to the updated terms, stop using the software and the site. Because the software is open source under the MIT License, you may continue to use any version you have already downloaded under the license that accompanied it. These terms govern the project website and our relationship with you as a user of the project. They do not override the MIT License, which continues to apply to the source code itself. If you want to track revisions, the public commit history for this page shows every change. We will not silently narrow your rights under these terms, and we will not retroactively remove a permission the MIT License already grants.
10. Governing law
These terms are governed by the laws of the Republic of Namibia, without regard to its conflict of law principles. Any dispute arising out of or relating to these terms, the software, or this website shall be resolved in the courts of Namibia, and you submit to the exclusive jurisdiction of those courts for that purpose. We chose Namibia because Tangison is owned and operated by Tangi Iigonda, who is based in Namibia. If you are outside Namibia, you are responsible for complying with any local laws that apply to your use of the software, including export control laws, sanctions, and data-protection laws. Nothing in these terms limits any consumer rights you may have under mandatory local law. If a court finds any provision of these terms unenforceable, the rest of the terms remain in effect. The original English version of these terms is the controlling version. Any translation is provided as a convenience only.
11. Contact
If you have a question about these terms, or if you want to negotiate a separate commercial agreement that overrides any section of them, the fastest way to reach us is WhatsApp. Message Tangi Iigonda directly through the button below. He replies within one business day. If your question is detailed or legal in nature, email is better. Write to contact@tangison.com and put "Terms question" in the subject line so it reaches the right inbox. You can also learn more about Tangison, its other projects, and its philosophy on sovereignty and open source at tangison.com. We welcome feedback on these terms. If a section reads like legalese and you think it could be clearer, tell us. We will rewrite it. Plain language is a feature, not a limitation. If you want to flag a potential issue with the software license, the repository, or any third-party dependency, use the same channels. We aim to acknowledge every legitimate report within one business day, and to publish a fix or a workaround as soon as we have one.
