1. Acceptance of these Terms

These Terms and Conditions (the "Terms") govern your access to and use of the Callisto Bridge website (callistobridge.com), the Keystone application (app.callistobridge.com), and all associated services (collectively, the "Service"). The Service is operated by TechStack Consulting LLC, founded by Daniel Michael Newland, a Texas limited liability company and the parent company of the Callisto Bridge product brand.

By accessing or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

2. The Service

Callisto Bridge is the brand under which TechStack Consulting LLC markets the Keystone product — a verified-asset rail for industrialized construction. Keystone comprises five engines: Module Registry, Capital Rail, Disbursement Rail, Insurance Rail, and the Modular Index. The Service is provided on an "as available" basis and is subject to evolution as the product develops.

3. Account registration

To access the Keystone application, you must create an account. You agree to provide accurate information, keep your credentials secure, and accept responsibility for activity occurring under your account. You must be at least 18 years of age and authorized to bind any organization on whose behalf you register.

4. Acceptable use

You agree not to:

Use the Service for any unlawful purpose or in violation of any applicable law or regulation
Attempt to access workspaces, accounts, or data not belonging to you
Circumvent the workspace isolation, row-level security, or any other access control
Introduce malware, viruses, or any malicious code into the Service
Interfere with or disrupt the operation of the Service
Reverse-engineer, decompile, or attempt to extract source code, except where permitted by law
Use automated means to access the Service except via our published APIs
Resell, sublicense, or otherwise commercialize the Service without our written authorization

5. Workspace data ownership

You retain ownership of the data you submit to your workspace ("Workspace Data"). You grant TechStack Consulting LLC a limited, worldwide, non-exclusive license to host, process, transmit, and display the Workspace Data solely to provide the Service to you. Industry-aggregated data — such as the Modular Index — may be derived from Workspace Data in de-identified form that does not identify your workspace, organization, manufacturer, or project.

6. Intellectual property

The Service, including the Keystone software, the Callisto Bridge brand, the website design, the Modular Index methodology, and all related materials, is owned by TechStack Consulting LLC or its licensors. Except for the license to use the Service granted in these Terms, no rights are granted to you, by implication or otherwise.

Module-related provenance, QA, and lifecycle records belong to the workspace that submitted them. Patent rights related to underlying industrialized-construction methods (where applicable) are held by the respective patent assignees and are not part of the rights granted under these Terms.

7. Fees and billing

Certain tiers of the Service — including the Modular Index licensing tiers (Standard, Pro, Enterprise) — are paid subscriptions. Subscription fees, billing cadence, and applicable taxes are specified in a separate written agreement with the subscriber. Trial, pilot, or design-partner access may be provided at no cost for a defined evaluation period.

8. Service availability

We aim to keep the Service available continuously, but do not guarantee uninterrupted access. We may suspend or restrict the Service for maintenance, security, legal, or operational reasons. We will provide reasonable notice of planned outages where practical.

9. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING (WITHOUT LIMITATION) MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE.

KeyScore values, pool ratings, insurance pricing, disbursement eligibility results, and all other outputs of the Service are informational. They are not financial advice, underwriting decisions, insurance quotes, or legal opinions. You are responsible for your own decisions made on the basis of Service outputs.

10. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TECHSTACK CONSULTING LLC AND ITS AFFILIATES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, GOODWILL, OR DATA, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE.

OUR AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) ONE HUNDRED DOLLARS ($100) OR (B) THE FEES PAID BY YOU TO US FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

11. Indemnification

You agree to defend, indemnify, and hold harmless TechStack Consulting LLC and its officers, directors, employees, and agents from any claims, damages, liabilities, and expenses (including reasonable attorneys' fees) arising out of your use of the Service, your Workspace Data, or your violation of these Terms.

12. Termination

You may terminate your account at any time by contacting us. We may suspend or terminate your access to the Service at any time if you violate these Terms or for legitimate operational reasons. Upon termination, the rights granted to you under these Terms cease. Provisions that by their nature survive termination (including Sections 5, 6, 9, 10, 11, 13, and 14) will continue to apply.

13. Governing law

These Terms are governed by the laws of the State of Texas, without regard to conflict of laws principles. Any dispute arising out of or related to these Terms shall be brought in the state or federal courts located in Texas, and the parties consent to the personal jurisdiction of those courts.

14. Changes to these Terms

We may update these Terms from time to time. Material changes will be communicated by updating the "Last Updated" date at the top of this page and, where required, by direct notice to account holders. Continued use of the Service after a change constitutes acceptance of the updated Terms.
