Terms of service.

These Terms of Service (the “Terms”) govern your use of Demiurge, including the Demiurge software, the associated websites and documentation at getdemiurge.com, and any related services (collectively, the “Service”). The Service is provided by Geoff Hire (“we”, “us”).

By installing, accessing, or using the Service, you agree to be bound by these Terms. If you don't agree, don't use the Service.

Creating an account requires a valid email address and a password (or OAuth sign-in). You are responsible for keeping your credentials confidential and for all activity that happens under your account.

You must be at least 13 years old to create an account. If you're creating an account on behalf of an organisation, you represent that you have authority to bind that organisation to these Terms.

Demiurge is a scaffolding layer around a frontier language model (currently Anthropic's Claude family). Model compute is included in your subscription; you pay us, and we handle the upstream provider relationship.

That dependency is worth calling out explicitly:

• Your prompts are sent to Anthropic's API on your behalf so the model can generate a response. Anthropic's own privacy and security practices govern what happens during that call. Their terms are available at anthropic.com/legal.
• Upstream availability is outside our control. If the Anthropic API experiences an outage, a regional degradation, or a rate-limit event, your turns may fail or slow down. We log these and absorb transient failures where we can; genuine upstream outages will affect the Service.
• If the upstream model provider changes pricing in a way that makes a plan's included compute unsustainable, we may need to adjust plan limits. Section 4 describes how those changes happen — with notice, and with the option to cancel without obligation for the upcoming period.

The Service offers multiple subscription plans (“Free Plan”, “Starter”, “Pro”, “Studio”) detailed on the pricing page. Paid plans are billed monthly in US dollars by our payments processor.

You authorise us to charge your payment method for the selected plan at the start of each billing period until you cancel. Cancellation takes effect at the end of the current billing period; we don't pro-rate refunds unless required by applicable law.

Plan limits — hourly rate caps, allowed models, and monthly compute ceilings — are enforced by the Service. We may adjust limits at any time with reasonable notice; if the change materially reduces what you've paid for, you may cancel immediately without obligation for the upcoming period.

You agree not to use the Service to:

• Violate any law or the rights of others, including intellectual property rights.
• Generate content that is illegal, harmful, deceptive, or infringes the rights of third parties.
• Reverse engineer, decompile, or otherwise attempt to extract the non-public source of the Service.
• Circumvent rate limits, billing controls, or the safety-architecture checks (sandbox, confirmation, undo registration).
• Resell access to the Service, or use a single account to support multiple distinct users beyond what the plan permits.
• Use the Service to probe, scan, or test the vulnerability of any system or network, or to breach security or authentication measures.

We may suspend or terminate accounts that violate these rules, with or without notice depending on the severity.

You retain all rights to the Unity projects, scripts, assets, prompts, and any other content you provide to or generate through the Service. You grant us a limited, non-exclusive license to process your content solely to operate the Service on your behalf — for example, forwarding your prompt to Anthropic so Claude can respond to it.

That license ends when your content leaves our systems, which is usually immediately after the request completes. See the privacy policy for the full retention + deletion story.

The Service itself — the Demiurge software, documentation, website, branding, and all associated original materials — is protected by copyright and other intellectual property laws. We grant you a limited, non-exclusive, non-transferable license to use the Service for its intended purpose during the term of your subscription.

Portions of the Demiurge codebase are available under specific open-source licenses in our public repository. Those portions are governed by their stated licenses, not by these Terms.

The Service is provided “as is” and “as available” without warranty of any kind.

To the maximum extent permitted by law, we disclaim all warranties, express or implied, including fitness for a particular purpose, merchantability, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or free from harmful components.

Specifically: generated code is a best effort by a frontier model plus scaffolding, not a guarantee. You are responsible for reviewing every script before running it in your project. The per-turn safety architecture (sandbox, confirmation prompt, undo registration) reduces but does not eliminate the risk of bad output.

To the maximum extent permitted by law, our aggregate liability arising out of or relating to the Service is limited to the greater of (a) the amount you paid us in the twelve (12) months preceding the event giving rise to the claim, or (b) one hundred US dollars.

We are not liable for indirect, incidental, consequential, special, or punitive damages — including lost profits, lost data, or business interruption — even if we have been advised of the possibility of such damages.

You agree to indemnify and hold us harmless from any claim or demand made by a third party arising out of your use of the Service, your content, your violation of these Terms, or your violation of any law or the rights of a third party.

You may cancel your subscription and delete your account at any time. We may suspend or terminate your account if you breach these Terms, if required by law, or if continuing to provide the Service becomes commercially impracticable.

Upon termination, your right to use the Service ends immediately. Provisions that by their nature should survive termination (sections 6-10, 13, 14) survive.

We may update these Terms from time to time. Material changes (those that reduce your rights or expand your obligations) will be announced by email to account holders at least 14 days before taking effect. Non-material changes (clarifications, fixes, expanded commitments to users) take effect immediately and are called out in our public release notes.

Continued use of the Service after a change takes effect constitutes acceptance of the updated Terms.

These Terms are governed by the laws of the State of California, without regard to conflict-of-laws principles. Any dispute arising under these Terms shall be resolved in the state or federal courts located in San Francisco County, California, and you consent to the personal jurisdiction of those courts.

Before filing a formal claim, you agree to contact us in good faith through the contact form and give us 30 days to resolve the issue informally.

• Entire agreement. These Terms plus the privacy policy are the entire agreement between you and us regarding the Service.
• Severability. If any provision is held unenforceable, the rest of the Terms remain in effect.
• No waiver. Our failure to enforce a provision is not a waiver of our right to enforce it later.
• Assignment. You may not assign your rights under these Terms without our written consent. We may assign ours in connection with a sale, merger, or reorganisation.

For any question about these Terms, use the contact form.

These Terms are intentionally plain-English and are not intended as legal advice. They describe the normal operating expectations of a developer-tool SaaS. If anything here surprises you or feels hostile, email us — we prefer fixing the policy to losing a customer.
