Terms and conditions

Last updated: July 20, 2026

These Terms and Conditions ("Terms") govern access to and use of the website, dashboard, and API operated by Aurex ("Aurex," "we," "us," or "our") (together, the "Services"). By creating an account, accessing our API, or otherwise using the Services, you agree to these Terms on behalf of yourself and the business you represent ("Merchant," "you," or "your"). If you do not agree, do not use the Services.

The Services

Aurex provides sales tax calculation, product classification, nexus monitoring, and filing infrastructure for businesses selling collectibles, precious metals, and other high-value goods. Specific features, pricing, and usage limits are described in your order form, the dashboard, or our then-current published plans.

Accounts

You must provide accurate information when creating an account and keep it up to date. You are responsible for safeguarding your API keys and account credentials, and for all activity that occurs under your account. Notify us promptly of any unauthorized use.

Merchant responsibilities

You are responsible for:

  • The accuracy of the transaction, product, and customer data you submit to the Services
  • Confirming the accuracy of tax registrations, exemption certificates, and filings before relying on them
  • Reviewing and approving filings prepared on your behalf prior to submission, where our plan includes filing preparation
  • Ensuring you have a lawful basis to submit any End Customer data to us
  • Complying with applicable law in your use of the Services, including tax collection and remittance obligations that remain yours as the merchant of record

Aurex's calculations, classifications, and nexus monitoring are decision-support tools based on the data you provide and the tax content available to us at the time of calculation. They do not constitute legal, tax, or accounting advice, and you remain responsible for your own tax compliance.

Fees and payment

Fees are set out in your order form or our published pricing. Unless stated otherwise, fees are billed in advance or based on usage in arrears, are non-refundable, and are exclusive of taxes, which you are responsible for (other than taxes on our net income). We may suspend access for accounts with amounts significantly past due, after reasonable notice.

Acceptable use

You will not, and will not permit others to: reverse engineer the Services except as permitted by law; use the Services to build a competing product; attempt to bypass rate limits or security controls; submit unlawful, fraudulent, or infringing content; or use the Services in a way that violates applicable law or these Terms.

Intellectual property

We retain all rights in the Services, including our software, tax content, and classification models. Subject to these Terms, we grant you a non-exclusive, non-transferable license to access and use the Services during your subscription term for your internal business purposes. You retain all rights in the data you submit to us ("Merchant Data"). You grant us a license to use Merchant Data to provide, maintain, and improve the Services.

Confidentiality

Each party may receive confidential information of the other in connection with these Terms. Each party will use the other's confidential information only to perform its obligations and exercise its rights under these Terms, and will protect it using at least reasonable care.

Disclaimers

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT TAX CALCULATIONS, CLASSIFICATIONS, OR FILINGS WILL BE ERROR-FREE OR THAT THEY WILL SATISFY YOUR SPECIFIC LEGAL OR REGULATORY OBLIGATIONS.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS OR REVENUE, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES. EACH PARTY'S TOTAL LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS WILL NOT EXCEED THE AMOUNTS PAID OR PAYABLE BY YOU TO US IN THE TWELVE MONTHS PRECEDING THE CLAIM. Nothing in these Terms limits liability that cannot be limited under applicable law.

Indemnification

You will indemnify and hold Aurex harmless from any claims, damages, and expenses (including reasonable attorneys' fees) arising from your breach of these Terms, your violation of applicable law, or your use of the Services, including reliance on our calculations, classifications, or filings without independent verification where required.

Term and termination

These Terms remain in effect for as long as you maintain an account or your subscription term, as applicable. Either party may terminate for the other's uncured material breach after written notice. We may suspend or terminate access for violations of the Acceptable Use section or to comply with law. Upon termination, your right to access the Services ends, though provisions that by their nature should survive (including payment obligations, confidentiality, disclaimers, and limitations of liability) will survive.

Changes to the Services or these Terms

We may update these Terms from time to time. If we make material changes, we will update the "Last updated" date above and, where appropriate, provide additional notice. Continued use of the Services after changes take effect constitutes acceptance of the updated Terms.

Governing law

These Terms are governed by the laws of the State of Delaware, without regard to conflict-of-laws principles, unless otherwise agreed in a signed order form.
