Terms of Service

Effective 2026-05-28 · DUEX (duex.app) · Toronto, Canada

DUEX is an early-stage product operated by Arvinder Singh from Toronto, Canada ("DUEX", "we", "us"). Contact: [email protected].

These terms apply when you use DUEX, take part in a pilot, or access any DUEX service. Visiting the public website on its own does not create a paid-service relationship. A signed pilot agreement may add to or override these terms for a specific customer pilot.

The service

DUEX is deal-review software for sales, revenue operations, and finance teams, with delivery right inside Slack coming soon. During early access, DUEX is offered through structured paid pilots with a clear scope and an agreed success metric. Early-access features may change, be limited, or be discontinued during the pilot. DUEX does not guarantee that any pilot feature will become generally available.

A few words we use a lot

What you can and can't do

The short version is in our Acceptable Use Policy — please read it. In summary:

Your data and the outputs

Outputs may be wrong — a person must review them

DUEX produces Output using automated language models. Any factual claim in an Output — including any statement about a deal, a counterparty, a contract clause, a price, a risk, or a person — may be incorrect, incomplete, misleading, or out of date. Models can also produce reasoning that sounds confident but is wrong (sometimes called a "hallucination").

You must have a qualified person review every Output against the source material, your company policy, and applicable law before relying on it. DUEX is not legal, financial, tax, accounting, or compliance advice, and is not a substitute for human business judgment, especially on material commercial decisions. You remain responsible for any decision you make based on an Output.

No high-risk decisions

DUEX is a sales workflow tool. It is not a tool for high-stakes decisions about people. You may not use DUEX, or any Output, as the sole or main basis for hiring or firing, credit or lending, healthcare, legal advice, housing, education access, government-benefits eligibility, or any decision that has legal effects on a person within the meaning of GDPR Article 22, or that would be a "high-risk AI system" under the EU AI Act. The Acceptable Use Policy has the full list.

Untrusted content in your inputs

Customer Content may contain text or instructions designed to manipulate the review or pull out information it shouldn't. DUEX uses technical and procedural controls to reduce that risk, but cannot guarantee that every malicious or conflicting instruction will be caught. Please review Outputs before relying on them.

Pilots and fees

Pilot fees, scope, usage targets, and termination rights are spelled out in the pilot agreement signed before the pilot begins. If anything here and the signed pilot agreement disagree, the signed pilot agreement applies.

Confidentiality

Each side may receive non-public business, technical, financial, product, security, or deal information from the other side. The side receiving the information will use it only to run or use the service, protect it with reasonable care, and not share it — except with personnel, contractors, subprocessors, or legal/accounting advisers who need to know, or as required by law.

We can suspend access

We may suspend your access right away if we reasonably believe your use creates a security risk, breaks these terms or the Acceptable Use Policy, may break the law or a Provider's rules, or may harm DUEX, another customer, or a Provider. We will restore access once the issue is resolved.

No warranty

DUEX is provided "as is" and "as available" during the early-access period, without warranties of any kind — whether express, implied, statutory, or otherwise — including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, completeness, or uninterrupted or error-free operation. You are solely responsible for verifying every Output before relying on it.

Limit of liability

To the maximum extent allowed by law, DUEX and its operator will not be liable for any indirect, incidental, consequential, special, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, business interruption, or reputational damage, even if we have been told the damages might happen.

Each side's total liability for direct damages arising out of or related to the service is limited to the fees you paid to DUEX for the applicable pilot during the 3 months before the event giving rise to the claim, or CAD $100 if no fees were paid. This cap does not apply to: (a) payment obligations, (b) breach of confidentiality, (c) misuse of the other side's intellectual property, (d) violation of the Acceptable Use Policy, or (e) liabilities that cannot be limited by law.

Any claim arising out of or related to the service must be brought within one year after the event giving rise to the claim, or be permanently barred.

IP indemnification

If a third party claims that the DUEX platform — not including your Customer Content or anything provided by a third-party review Provider — infringes a valid patent, copyright, or trademark, DUEX will defend you and pay any court-ordered damages or settlement amounts, as long as you (a) tell us about the claim promptly, (b) let us control the defense and any settlement, and (c) reasonably cooperate with us. This does not apply to claims that arise from your use of DUEX outside what these terms allow.

Export and sanctions

You may not use DUEX if you are located in, organized under the laws of, or ordinarily resident in a country or region subject to comprehensive US or Canadian sanctions, or if you are on a US, Canadian, EU, or UK sanctions or restricted-party list. You are responsible for following all export-control and sanctions laws that apply to you.

Governing law

These terms are governed by the laws of the Province of Ontario, Canada, without regard to conflict-of-law principles. Any disputes will be resolved in the courts located in Toronto, Ontario.

Changes

We may update these terms as DUEX grows. The effective date at the top reflects the most recent revision.
