Terms and conditions

The terms governing use of the Byron platform and website.

‍

Last updated: May 1st, 2026

These Terms of Service (“Terms”) govern your use of the Byron platform and the website at usebyron.com (collectively, the “Service”) provided by Rialto Finance, Inc. (“Byron,” “we,” “us,” or “our”). These Terms are a binding agreement between Byron and the individual or entity accessing the Service (“Customer,” “you,” or “your”).

By accessing or using the Service, you agree to be bound by these Terms. If you are accessing the Service on behalf of a firm or other organization, you represent that you have the authority to bind that organization to these Terms, and “you” refers to that organization.

If you do not agree to these Terms, do not use the Service.

1. The Service

Byron provides software-as-a-service tools that automate parts of tax return preparation, including extracting data from tax documents, generating workpapers, and exporting data to tax preparation software. The specific features available to you depend on your subscription plan, as set forth in your Order Form or other written agreement with Byron.

We may modify, add, or remove features of the Service at our discretion. We will provide reasonable notice of material changes that adversely affect your use of the Service.

2. Account registration and eligibility

To use the Service, your firm must register an account and designate one or more administrators. The administrator is responsible for managing user access within the firm and for the actions of all users on the firm’s account.

You agree to:

Provide accurate and complete account and registration information.
Keep your account credentials confidential and not share them.
Notify us promptly at support@usebyron.com of any unauthorized use of your account.
Use the Service only for lawful business purposes and only in connection with your firm’s tax preparation work.

You may not use the Service if you are under 18 years of age.

3. Acceptable use and restrictions

You will not, and will not allow any third party to:

Reverse engineer, decompile, disassemble, or attempt to derive the source code or underlying logic of the Service.
Use the Service to develop, train, or improve any product or service that competes with the Service, including any artificial intelligence or machine learning model.
Resell, rent, lease, sublicense, or otherwise commercially exploit the Service except as expressly permitted.
Access the Service through automated means (bots, scrapers, etc.) except through APIs we expressly make available.
Interfere with the integrity, performance, or security of the Service.
Upload or transmit any unlawful, infringing, or harmful content.
Use the Service in a way that violates any applicable law, regulation, or third-party right.

We may suspend or terminate your access if we reasonably believe you are violating this section.

4. Customer data

Ownership. As between you and Byron, you retain all right, title, and interest in and to the data you upload to the Service or that the Service generates on your behalf, including tax documents, extracted values, workpapers, and exports (“Customer Data”).

‍Limited license to Byron. You grant Byron a limited, non-exclusive, worldwide license to host, process, transmit, and display Customer Data solely as necessary to provide and improve the Service for you, to comply with legal obligations, and as otherwise expressly permitted under these Terms.

‍Customer responsibilities. You are responsible for the accuracy, legality, and appropriateness of Customer Data, for obtaining all rights and consents needed to upload Customer Data to the Service (including any consents required from your own clients), and for ensuring that your use of the Service complies with applicable laws, including tax, privacy, and data protection laws.

‍Data security. Byron maintains administrative, technical, and physical safeguards designed to protect Customer Data, as further described in our Privacy Policy and How we protect client data. No system is completely secure, however, and Byron does not guarantee absolute security.

5. AI and machine learning

Byron uses artificial intelligence and machine learning as part of the Service. The following commitments apply:

We do not use Customer Data to train, fine-tune, or otherwise improve generally available third-party AI models.
Where the Service relies on third-party AI providers, we engage them under contractual terms that prohibit them from using submitted data to train their own models.
The Service may use de-identified, aggregated data — that cannot reasonably be used to identify you, your firm, or your clients — to operate, debug, and improve the Service and for related diagnostic purposes.

6. Intellectual property

The Service, including all software, content, designs, logos, documentation, and improvements, is owned by Byron or its licensors and is protected by intellectual property laws. Subject to your compliance with these Terms, Byron grants you a non-exclusive, non-transferable, revocable license to access and use the Service during your subscription term solely for your firm’s internal business purposes.

No other rights are granted by implication or otherwise. All rights not expressly granted to you are reserved by Byron.

If you provide Byron with feedback, suggestions, or ideas about the Service (“Feedback”), you grant Byron a perpetual, worldwide, royalty-free license to use that Feedback for any purpose, without obligation to you.

7. Fees and payment

Fees for the Service are set forth in your Order Form or in the pricing made available to you at the time of subscription. Unless otherwise stated:

Fees are due according to the schedule in your Order Form.
Fees are non-refundable except as expressly required by law or as set forth in your Order Form.
You are responsible for any taxes associated with your use of the Service, other than taxes based on Byron’s net income.
Late payments may accrue interest at the lower of 1.5% per month or the maximum permitted by law.
Byron may suspend the Service for non-payment after providing reasonable notice and an opportunity to cure.

8. Term and termination

These Terms remain in effect for the subscription term set forth in your Order Form and will renew automatically as set forth there unless either party provides notice of non-renewal in accordance with the Order Form.

Either party may terminate these Terms for cause if the other party materially breaches these Terms and fails to cure the breach within the agreed period.

On termination, your right to access and use the Service ends immediately. Byron will delete Customer Data within 60 days of termination, except where retention is required by law or by these Terms.

Sections of these Terms that by their nature should survive termination — including Customer Data ownership, intellectual property, fees owed, confidentiality, indemnification, warranty disclaimers, and limitation of liability — will survive termination.

9. Confidentiality

Each party may have access to the other party’s non-public business, technical, or financial information (“Confidential Information”). The receiving party will use reasonable care to protect the disclosing party’s Confidential Information and will use it only as needed to perform under these Terms. Confidential Information does not include information that is publicly available, was already known to the receiving party without obligation of confidence, was independently developed without use of the disclosing party’s Confidential Information, or is required to be disclosed by law (in which case the receiving party will provide reasonable advance notice where lawful).

10. Third-party integrations

The Service may integrate with third-party tax preparation software and other third-party services (“Third-Party Services”). Your use of any Third-Party Service is subject to that third party’s own terms and privacy practices. Byron is not responsible for Third-Party Services and does not warrant their accuracy, availability, or compliance with applicable laws.

11. Beta and early-access features

Byron may make features available on a beta, preview, or early-access basis (“Beta Features”). Beta Features are provided “as is” for evaluation purposes, may be modified or discontinued at any time, and may not be subject to the same service commitments as generally available features. We may collect feedback on Beta Features as part of their development.

12. The Service is not professional advice

The Service is a software tool for tax professionals. It does not provide, and is not a substitute for, legal, tax, accounting, financial, or other professional advice. You are solely responsible for the accuracy and completeness of any tax return or filing prepared with the assistance of the Service, for reviewing all extractions and exports before submission, and for compliance with all applicable professional and regulatory standards.

13. Warranties and disclaimers

Byron warrants that it will provide the Service in a manner consistent with applicable industry standards.

EXCEPT AS EXPRESSLY SET FORTH IN THESE TERMS, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” BYRON DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. BYRON DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE FROM HARMFUL COMPONENTS, OR THAT ANY DATA WILL BE COMPLETELY SECURE OR FREE FROM LOSS.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL BYRON OR ITS AFFILIATES, OFFICERS, EMPLOYEES, AGENTS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION DAMAGES FOR LOST PROFITS, LOST REVENUE, LOST DATA, BUSINESS INTERRUPTION, OR COST OF SUBSTITUTE SERVICES, ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE, WHETHER BASED IN CONTRACT, TORT, OR ANY OTHER THEORY, EVEN IF BYRON HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

BYRON’S TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE TOTAL FEES PAID OR PAYABLE BY YOU TO BYRON FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

THE LIMITATIONS IN THIS SECTION APPLY EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

15. Indemnification

By you. You will defend, indemnify, and hold harmless Byron and its affiliates, officers, employees, and agents from and against any third-party claim arising out of or relating to: (a) your or your users’ use of the Service in violation of these Terms or applicable law; (b) Customer Data, including any claim that Customer Data infringes a third party’s rights or violates law; or (c) your professional services or work product, including the tax returns you prepare using the Service.

‍By Byron. Byron will defend, indemnify, and hold harmless Customer from and against any third-party claim alleging that the Service, when used in accordance with these Terms, infringes a U.S. patent, copyright, or trademark of that third party. Byron’s obligation does not apply to claims arising from Customer Data, third-party services, modifications to the Service not made by Byron, or use of the Service outside the scope of these Terms.

The indemnified party will provide prompt written notice of the claim, give the indemnifying party sole control of the defense (provided it does not settle in a way that admits liability or imposes an obligation on the indemnified party without consent), and reasonable cooperation.

16. Privacy

Our Privacy Policy describes how we collect, use, and protect personal information in connection with the Service. The Privacy Policy is incorporated into these Terms by reference.

17. Modifications to the Terms

We may modify these Terms from time to time. When we do, we will update the “Last updated” date at the top of this page. For material changes, we will provide reasonable advance notice through the Service, by email, or by other appropriate means. Your continued use of the Service after the effective date of changes constitutes acceptance of the updated Terms. If you do not agree to the updated Terms, you must stop using the Service.

18. Governing law and dispute resolution

These Terms are governed by the laws of the State of California, without regard to conflict of laws principles.

All disputes shall be resolved through binding arbitration under the rules of JAMS in San Francisco, California.

19. Miscellaneous

Entire agreement. These Terms, together with any Order Form and any other agreements expressly referenced, constitute the entire agreement between you and Byron and supersede any prior agreements relating to the Service.

‍Assignment. You may not assign or transfer these Terms without Byron’s prior written consent, except to a successor in connection with a merger, acquisition, or sale of substantially all of your assets. Byron may assign these Terms without restriction. Any attempted assignment in violation of this section is void.

‍Severability. If any provision of these Terms is held unenforceable, the remaining provisions will remain in full effect, and the unenforceable provision will be modified to the minimum extent necessary to make it enforceable.

‍No waiver. Failure to enforce any provision of these Terms is not a waiver of that provision.

‍Force majeure. Neither party is liable for failure to perform due to causes beyond its reasonable control, including natural disasters, war, terrorism, labor disputes, governmental action, or interruption of internet or utility services.

‍Notices. Notices to Byron under these Terms must be sent to support@usebyron.com. Notices to you may be sent to the email address associated with your account.

‍Independent contractors. The parties are independent contractors. These Terms do not create any agency, partnership, joint venture, or employment relationship.
