Terms of Use

Who we are and who may use the Services

Arqa is an AI floor-planning service: you describe a home or building and our models and solver produce conceptual floor plans, drawings and related design material.

You must be at least 18 years old, or the age of majority where you live, to use the Services. If you use the Services on behalf of a company or another person, you confirm you are authorised to accept these Terms for them.

Accounts and access

You get an account by requesting access to the web app on our waitlist, which we review by hand. Connecting Arqa in ChatGPT or Claude uses that account and its password; it creates no account. We may suspend or disable accounts that break these Terms.

You are responsible for your account credentials and for activity under your account, including activity by apps you connect to it (for example ChatGPT or Claude). Tell us promptly if you believe your account has been compromised. You can disconnect a connected app at any time; we may revoke sessions and connections to protect your account.

Using our Services

You may use the Services in compliance with these Terms and applicable law. You may not:

• use the Services in a way that infringes, misappropriates or violates anyone’s rights, or to harm, harass or deceive others;
• attempt to access accounts, projects or data that are not yours, or bypass access controls, rate limits, credit checks or the waitlist;
• reverse engineer, scrape or systematically extract our models, prompts, pipeline or data, except as permitted by law;
• use outputs to develop models that compete with the Services;
• interfere with or disrupt the Services, including by sending malicious code or automated traffic beyond documented API limits;
• represent outputs as professionally certified, permit-ready or human-reviewed when they are not.

Your content

You may provide input to the Services ("Input"), such as briefs, room programs, locations, uploaded images and edits, and receive output ("Output"), such as floor plans, drawings, schedules and replies. Input and Output are "Content".

As between you and us, and to the extent permitted by law, you own your Input and, subject to these Terms, we assign to you our rights in the Output. Outputs may be similar to outputs produced for other users; you do not acquire rights in other users’ outputs or in our solver, templates and models.

You are responsible for your Content, including making sure you have the rights to the Input you provide (for example uploaded drawings or photos).

How we use Content to improve and train our models

We use Content to provide and maintain the Services, and to develop and improve them. This includes training, fine-tuning and evaluating our own models and our planning pipeline on model requests and responses, generated plans, the errors you flag, and the corrections and comments you give us.

Training data may be reviewed by people working with us and processed by service providers that run our training jobs, under confidentiality obligations. The Privacy Policy describes what we collect for this, how long we keep it and how to ask us to exclude your Content from training.

Accuracy and concept designs

Artificial intelligence is probabilistic and can produce output that is incomplete, inaccurate or unsuitable for your site. Plans, areas, code checks, MEP layouts, data-center figures and other outputs are indicative concept material only.

Outputs are not construction documents, permit sets, engineering calculations or a substitute for review by qualified architects, engineers, contractors and local authorities. Code checks are approximations of the referenced codes, not a compliance certificate. Have any output independently reviewed before relying on it.

Credits, payments and the developer API

Some features use credits. The price of an action is reserved before the work starts and refunded if the action fails or you stop it. Prices, credit packs and any expiry are shown in the Services before you buy or spend credits. Payments are processed by our payment provider (Stripe) under its terms.

Credits are not cash, are not transferable and are non-refundable except where required by law or stated at purchase. Purchases happen only in the Arqa app. The same actions use credits wherever you run them: in the Arqa app, through ChatGPT or Claude, or through the developer API; when you run out we ask you to buy more before continuing.

The developer API uses separate API keys, approval and billing, documented at /docs. API keys work only on the API and must be kept secret.

Connected apps and third-party services

The Services rely on third parties, including model providers, mapping and climate data, hosting and payments. When you use Arqa through a third-party app such as ChatGPT or Claude, that app’s own terms and privacy policy also apply to what you do there; we receive only what the app sends us for each request.

Our rights

We own the Services, including our software, models, prompts, solver, templates, drawings conventions and brand. Except for the rights to your Content described above, these Terms do not grant you any rights in them. Feedback you give us may be used without restriction or compensation.

Suspension and termination

You may stop using the Services at any time and ask us to delete your account. We may suspend or end your access if you breach these Terms, if required by law, or to protect the Services or other users. Where reasonable we will tell you first. Sections that by their nature should survive termination will survive.

Disclaimers and limitation of liability

The Services are provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement and that the Services will be uninterrupted, error-free or that outputs will be accurate or compliant.

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or exemplary damages, or for loss of profits, data or goodwill, and our total liability for any claim relating to the Services is limited to the greater of the amount you paid us in the 12 months before the claim or USD 100. Nothing in these Terms limits liability that cannot be limited by law.

Changes to these Terms

We may update these Terms as the Services change. We will post the new version here with a new date and, for material changes, give notice in the Services or by email before they take effect. Continuing to use the Services after that means you accept the updated Terms.
