The rules of the road,
without the trapdoors.

01The agreement

This is a contract between you (or the organization you represent — "Customer", "you") and Arcus AI, Inc. ("Arcus", "we"), a Delaware corporation. It governs your use of the Arcus reasoning workspace, our website, and anything we publish under usearcus.ai (collectively, "the Service").

By creating an account, signing a quote, or clicking "I agree", you tell us you've read this and you have the authority to bind your organization. If you don't have that authority, don't click the button.

02Your account

One human per login. Don't share credentials; don't let bots act as users. You're responsible for what happens under your account, including charges, until you tell us a credential is compromised — at which point we'll lock it within an hour of confirmation.

If you're an admin, you also accept these terms on behalf of every user you invite. Tell them about your acceptable-use policy before you give them a seat.

03What you may do

Within your subscription or pilot scope you may use the Service to ask questions, review answers, build approved artifacts, and share results, as long as you stay within (a) the limits of your signed agreement or workspace configuration and (b) the rules in §4.

You may publish individual answers, charts, memos, and dashboards externally — to your investors, your customers, your regulator. You don't need our permission. Crediting Arcus is appreciated, never required.

04What you may not do

Don't:

• Try to circumvent rate limits, authentication, or our security controls.
• Use the Service to build a competing reasoning product, train a model on its outputs, or scrape it for offline reuse.
• Load data you don't have the legal right to process — including unconsented PII, stolen credentials, or third-party data under NDA without their permission.
• Use the Service to do something illegal, harassing, or harmful — including bulk profiling people in ways their jurisdiction forbids.
• Send prompts or data designed to extract or expose other tenants' data, our prompts, or our models. We treat this as a security incident.
• Resell, sublicense, or expose the Service to non-licensed users via a wrapper. Embedding individual outputs in your product is fine; reselling the Service itself is not.

Violation gives us the right to suspend the offending user or workspace immediately, with notice and (where possible) a chance to cure. Egregious violations may end the contract without refund.

05Your data, your rights

You own everything you bring to Arcus and everything Arcus produces from it. We claim no rights to your prompts, your source data, your threads, your memos, your dashboards, or your audit log.

You grant us a narrow, non-exclusive license to process that data only as needed to run the Service for you (compute the answer, render it, store it where you tell us to, deliver it to your channels). That license ends when the data leaves the Service.

Specifically, we will not: train models on your data, sell it, share it for advertising, or use it to develop unrelated products. The full data-handling promise is in our Privacy Policy and operationalized in our Data Processing Addendum.

06AI output & reliance

Arcus is a reasoning system. It synthesizes answers from your data and from large language models. The system is good. It is not infallible.

• Always verify high-stakes outputs against the cited sources. Every answer ships with lineage; use it.
• Don't use Arcus output as the sole basis for medical, legal, financial, or safety-of-life decisions without a qualified human review.
• You are responsible for the consequences of acting on Arcus output, including outputs your team automates.

07Fees, billing & refunds

Fees, billing terms, renewal terms, usage limits, and support commitments are defined in your signed order form, pilot agreement, or billing settings where available. The public Pricing page describes current engagement paths but does not override a signed agreement.

• Taxes are added where required by law and shown on your invoice before charge.
• Usage limits and overage apply only when stated in your order form or billing settings.
• Refunds are handled according to your signed agreement and applicable law.
• Auto-renewal applies only when stated in your signed agreement or billing settings.
• Past due: If an invoice is more than 15 days late we may suspend; more than 60 days, we may terminate. We'll always email you first.

08Term & termination

The term starts when you sign up, start a pilot, or sign an order form and continues until cancelled or expired under the applicable agreement. Either party may end it for material breach with 30 days' notice and a chance to cure. We may end it immediately for non-payment after notice, or for the egregious-violation cases in §4.

On termination: you keep export rights for 30 days, after which we delete your tenant unless you ask in writing to extend. We refund pre-paid, unused fees only when we end the contract for our reasons (not yours).

09Warranties & disclaimers

What we promise. We will provide the Service with reasonable care and skill, materially as described in our docs, in compliance with our Privacy Policy and DPA, and with the security controls listed at usearcus.ai/trust.

What we don't promise. Unless a signed agreement says otherwise, we don't warrant that the Service will be uninterrupted, error-free, or that AI output will be accurate in every case. Except as expressly written here, the Service is provided "AS IS" to the maximum extent allowed by law.

10Limitation of liability

Neither party is liable to the other for indirect, consequential, special, or incidental damages, or for lost profits or revenue, even if advised of the possibility.

Each party's total aggregate liability under these terms is capped at the greater of (a) the fees you paid us in the 12 months before the claim, and (b) USD 50,000. The cap does not apply to: breach of confidentiality, IP indemnity (§11), gross negligence, or willful misconduct.

We do not use AI hallucination as an excuse to avoid responsibility for actual security failures, data breaches, or breaches of our written commitments.

11Indemnification

From us, to you. We'll defend you from third-party IP claims that the Service infringes their copyright, trademark, or US patent — and pay any settlement or final judgment — provided you tell us about the claim promptly and don't admit liability without our consent.

From you, to us. You'll defend us from third-party claims arising out of your data, your use of the Service in violation of §4, or your distribution of outputs you weren't entitled to publish.

That's the deal. No theatrical "you indemnify us against everything in the universe" language.

12Changes & conflicts

We may update these terms. For material changes (anything affecting your rights, fees, or data) we email all admins 30 days before the change takes effect and post a redline. Continued use after the effective date counts as acceptance. If you don't accept, cancel before the effective date for a full prorated refund.

If a quote or order form you signed says something different than this page, the order form wins.

13Governing law & disputes

These terms are governed by the laws of the State of New York, USA, without regard to conflict-of-law rules. The courts of New York County, New York have exclusive jurisdiction; both parties waive any right to a jury trial.

Before filing a lawsuit, the parties agree to escalate in good faith to a senior leader on each side and try to resolve the dispute within 30 days. We'll waive that step for genuine emergencies (preliminary injunctions, IP issues that need immediate relief).

EU and UK customers: nothing in this section deprives you of mandatory consumer protections in your jurisdiction.

14Miscellaneous

• Force majeure. Neither party is liable for failures caused by events outside reasonable control — except neither party is excused from paying money owed.
• Assignment. Either party may assign these terms to an affiliate or successor in a corporate event with notice.
• Independent contractors. No agency, partnership, joint venture, or employment is created.
• Notices. Email is fine. To us: legal@usearcus.ai. To you: the admin email on your account.
• Severability & waiver. If a clause is unenforceable, the rest survives. Failure to enforce a right is not a waiver.
• Entire agreement. These terms, the Privacy Policy, the DPA, your active order form/MSA, and any in-product policies you accept are the whole deal.
