End User License Agreement

Effective Date: 8/16/2026 Last Updated: 8/16/2026

1. Acceptance of Terms

This End User License Agreement (“Agreement”) is a binding contract between you (“User” or “you”) and C4 Hot Rods, [LEGAL ENTITY TYPE — e.g. LLC, Inc.] (“C4 Hot Rods,” “we,” “us,” or “our”) governing your access to and use of C4 Argus (the “Application”), an internal business-intelligence tool that allows authorized C4 Hot Rods personnel to ask questions about company operating data — including data accessed from Intuit QuickBooks Online via the Intuit Developer Platform, from Google Drive, and from Time Tracker by eBillity — using natural language.

By accessing or using the Application, you acknowledge that you have read, understood, and agree to be bound by the terms of this Agreement. If you do not agree, you may not access or use the Application.

2. Eligibility & Authorized Use

The Application is provided exclusively for the internal business use of C4 Hot Rods and its authorized employees, contractors, and agents. You may only access the Application if you have been issued valid credentials by C4 Hot Rods and your access has not been revoked.

The Application is not offered to the general public and is not a service sold to or made available to third parties. Any attempt to access or use the Application without authorization is strictly prohibited and may be subject to civil and criminal penalties.

3. License Grant

Subject to your compliance with this Agreement, C4 Hot Rods grants you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to access and use the Application solely for legitimate C4 Hot Rods business purposes during the term of your authorization.

4. Restrictions

You shall not, and shall not permit any third party to:

  • Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code or underlying ideas, algorithms, or structure of the Application;
  • Modify, adapt, translate, or create derivative works of the Application;
  • Rent, lease, lend, sell, sublicense, distribute, or otherwise transfer the Application or rights granted under this Agreement;
  • Remove, alter, or obscure any proprietary notices, including copyright, trademark, or attribution notices;
  • Use the Application to transmit malicious code, attempt unauthorized access to other systems, or interfere with the operation of the Application;
  • Use the Application in any manner that violates applicable laws, regulations, or third-party rights, including the Intuit Developer Agreement, applicable QuickBooks terms, the Google API Services User Data Policy, and applicable eBillity terms;
  • Share your access credentials — including any connector URL issued to you — with any other person, or allow another person to use your access;
  • Export or extract data from the Application in bulk for use outside the scope of authorized C4 Hot Rods business purposes;
  • Disclose customer names, vehicle details, pricing, or financial figures obtained through the Application to anyone outside C4 Hot Rods without express authorization.

5. Connected Services and Data Sources

The Application reads data from third-party services on C4 Hot Rods’ behalf. By using the Application, you acknowledge that:

  • The Application is read-only with respect to every connected service. It contains no capability to create, modify, or delete any record in QuickBooks Online, Google Drive, or Time Tracker by eBillity. Its own database records only the interpretations and review decisions described in Section 6.
  • Data accessed by the Application is the property of C4 Hot Rods and is governed by C4 Hot Rods’ applicable data and information-security policies.
  • You will not use, copy, export, or disclose data accessed through the Application except as authorized by C4 Hot Rods and in compliance with applicable third-party terms.
  • The Application does not read, store, or expose payment card numbers, card verification values, bank account or routing numbers, ACH instructions, tax identification numbers (including EINs, SSNs, and ITINs), government-issued identification numbers, or dates of birth.
  • Intuit and its terms (including the Intuit Privacy Statement and the Intuit Developer Agreement) govern the underlying connection to QuickBooks Online; Google’s terms govern the underlying connection to Google Drive; eBillity’s terms govern the underlying connection to Time Tracker. This Agreement governs only your use of the Application itself.
  • Access to any connected service may be revoked by C4 Hot Rods or by the third-party provider at any time, and the Application may become partially or wholly unavailable as a result.

6. Nature of the Information Presented

The Application presents information derived from operational records that were created for other purposes. You acknowledge and agree that:

  • Estimates are not invoices. Figures drawn from estimate documents represent work that was *quoted*, which may include quotes that were revised, superseded, declined, or never accepted. They must not be treated as revenue, as amounts owed, or as amounts collected.
  • Certain records require human confirmation before they are counted. The Application deliberately withholds documents from any total until an authorized person has confirmed what those documents represent. Figures presented as pending confirmation are not authoritative.
  • Information may be out of date. Where the Application reports the age of the underlying data, you are responsible for taking that age into account. Data that has not been refreshed does not reflect activity occurring since the last refresh.
  • Some values are interpreted rather than recorded. Where source records contain free-form notes, the Application may infer structure from them. Such interpretations are estimates and are identified as requiring review.

7. Employee Time and Work Records

The Application may present employee and contractor time records, job assignments, and derived measures of billable time.

  • Such information is presented for legitimate business purposes including scheduling, job costing, capacity planning, and operational review.
  • Derived measures are calculated from time entries as recorded and may be incomplete where time has not been entered, entered late, or attributed to the wrong job. They are not a complete or authoritative record of any individual’s work.
  • No employment decision affecting any individual should be made on the basis of Application output alone, without independent verification and review of the underlying records.
  • Access to individual-level time information is restricted to personnel with a legitimate business need.

8. Intellectual Property

The Application, including all software, content, features, functionality, design, documentation, and underlying technology, is the exclusive property of C4 Hot Rods and its licensors and is protected by United States and international copyright, trademark, patent, trade secret, and other intellectual property laws.

No rights or licenses are granted by implication, estoppel, or otherwise, except as expressly set forth in this Agreement.

9. User Responsibilities & AI-Generated Content

You are responsible for maintaining the confidentiality of your access credentials, including any connector URL issued to you, and for all activity occurring under your access. You agree to notify C4 Hot Rods immediately of any unauthorized access, credential disclosure, or security breach of which you become aware.

You acknowledge that the Application interprets natural-language questions using artificial intelligence, and that responses it generates — while grounded in underlying business data — may be incomplete, may misinterpret a question, or may present accurate figures in a misleading context. You will exercise reasonable professional judgment in evaluating responses before relying on them, and you will not use the Application as the sole basis for decisions having significant legal, financial, employment, or customer-facing consequences without independent verification against the underlying records.

10. Disclaimers

THE APPLICATION IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. C4 HOT RODS EXPRESSLY DISCLAIMS ALL WARRANTIES, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED OPERATION.

Without limiting the foregoing, C4 Hot Rods does not warrant that (a) the Application will meet your requirements; (b) operation of the Application will be uninterrupted or error-free; (c) defects in the Application will be corrected; or (d) information presented by the Application will be complete, accurate, or current.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL C4 HOT RODS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE APPLICATION, REGARDLESS OF THE LEGAL THEORY ON WHICH SUCH CLAIM IS BASED, EVEN IF C4 HOT RODS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

12. Termination

C4 Hot Rods may suspend or terminate your access to the Application at any time, with or without notice, for any reason, including breach of this Agreement, termination of your employment or contractor relationship with C4 Hot Rods, or any actual or suspected unauthorized use. Upon termination, you must immediately cease all use of the Application, destroy any copies of materials obtained from it, and delete any connector URL or credential issued to you.

13. Updates and Modifications

C4 Hot Rods may update or modify the Application or this Agreement at any time. We will provide notice of material changes by posting an updated version at the same URL where this Agreement is published, and the “Effective Date” at the top of this document will be revised. Your continued use of the Application after such changes constitutes your acceptance of the updated Agreement.

14. Governing Law & Dispute Resolution

This Agreement is governed by and construed in accordance with the laws of the State of Colorado, without regard to its conflict of laws principles. Any dispute arising out of or relating to this Agreement shall be resolved exclusively in the state or federal courts located in Denver County, Colorado, and the parties consent to the personal jurisdiction of those courts.
