By using the Syntaur application or anything published on syntaur.app, you agree to the following. These terms are brief because the product surface they cover is intentionally narrow today; they will be expanded if and when that changes.
About "Syntaur Systems": Syntaur Systems is the trade name under which Sean Cherry operates the Syntaur product. References to "we," "us," and "Syntaur Systems" in these terms refer to Sean Cherry doing business as Syntaur Systems.
The marketing site at syntaur.app is provided as-is for informational purposes. Nothing on the site is a binding offer, contract, or guarantee. We may change the content at any time.
The Syntaur application is proprietary software of Syntaur Systems. The core experience — the main-screen chat and agent — is free to use, with no fee or account required. Additional module components and functionality are unlocked with a one-time purchase. Binaries are distributed from github.com/syntaur-systems/syntaur-dist; the software is provided "as is," without warranty of any kind. You are responsible for how you deploy and operate the gateway on your own hardware, including any third-party services you connect it to. Syntaur Systems is not a party to those third-party services and accepts no liability for actions taken by or against those services through your installation.
AI output is not professional advice. Syntaur relies on AI models — including smaller or local models you may choose to run — to generate chat responses, agent actions, and module output. AI can be wrong: it may produce inaccurate, incomplete, outdated, or misleading information, and the likelihood of error is generally higher on lower-capability models. Anything Syntaur generates — including assistance with taxes, finances, health, or any other regulated or high-stakes matter — is provided for informational and convenience purposes only. It is not legal, tax, financial, medical, or other professional advice, and is not a substitute for a qualified professional (such as a CPA, attorney, or physician). You are solely responsible for reviewing and verifying any AI-generated output before relying on it, and for any decisions or actions you take based on it. To the fullest extent permitted by law, Syntaur Systems is not liable for any loss, damage, tax penalty, health outcome, or other harm arising from reliance on output produced by the software or its AI agents.
Pass-through integrations with regulated providers (e-file partners, payment processors, etc.) are governed by your relationship with those providers. Syntaur Systems is the intermediary; we route preparations to the provider and route their published per-transaction charges to you at cost, but the underlying service obligation and any service-level commitments are between you and that provider.
