PlanFlag — Terms of Service

Effective date: June 20, 2026 · Version: 2026-06-20

These Terms of Service ("Terms") govern your access to and use of PlanFlag (the

"Service"), operated by Computer Services International, LLC, a Missouri limited

liability company and parent of the Highpass Studio brand ("PlanFlag," "we,"

"us"). By creating an account or using the Service, you agree to these Terms.

1. Acceptance of Terms

By creating an account or using PlanFlag, you agree to these Terms. You represent

that you are authorized to enter this agreement, on your own behalf or for the

organization you represent, and that you are at least 18 years old. Acceptance is

per individual user: each user accepts these Terms for themselves, even where

multiple users belong to the same organization. If you do not agree, do not use

the Service.

2. Description of the Service

PlanFlag is an AI-assisted quality-assurance and quality-control aid for

construction plan-set review. It surfaces candidate findings, checklist items,

and table or schedule discrepancies for a licensed professional to evaluate. It

is a software tool. It is not an engineering firm and not a licensed

professional.

3. Not a Substitute for Professional Engineering Judgment

PlanFlag assists a qualified reviewer; it does not perform engineering, does not

constitute a professional engineering review, and does not seal, stamp, certify,

or approve any document. Its output is informational only and must be

independently verified by a licensed professional exercising their own judgment.

reviewing professional remains solely responsible for their review and for any

decision to act, or not to act, on PlanFlag output.

threshold inspector, or plan reviewer of record, and creates no such

professional duty.

use it to seal or stamp documents, or use it in any way that violates

professional licensing law.

4. No Warranty of Completeness or Accuracy

PlanFlag may miss real issues and may surface items that are not issues. It does

not and cannot guarantee that it identifies every defect, omission, code

violation, or coordination problem in a plan set, or that any finding is correct.

A clean or short PlanFlag result is not evidence that a plan set is complete or

compliant. You must not rely on PlanFlag as a complete or authoritative review.

Where provided, PlanFlag's coverage disclosures describe only what was assessed,

not a guarantee of what was found.

5. Your Documents

Plan sets, drawings, and files you upload ("Customer Documents") remain the

property of you and your clients. You grant us only the limited, non-exclusive

license necessary to host, process, and deliver the review you request, and to

maintain it for your access. We will not use the content of Customer Documents to

train machine-learning models. We retain Customer Documents for three months, and

we delete them upon closure of your account. You represent that you have the right

to upload them.

6. Feedback and Evaluation Data

"Feedback" means any grade, rating, correction, label, severity adjustment,

confirmation, rejection, or comment you or your users submit about findings or

outputs generated by the Service. Feedback does not include, and this license

does not extend to, the content of your Customer Documents (the drawings and plan

sets themselves), which are governed by Section 5.

You grant us a worldwide, perpetual, irrevocable, non-exclusive, royalty-free,

sublicensable, and transferable license to use, store, reproduce, modify,

aggregate, and create derivative works from Feedback for any purpose related to

operating, evaluating, and improving the Service and developing related products,

including training, validating, and tuning machine-learning models and rule sets.

Models, calibration datasets, check definitions, and other artifacts derived from

Feedback are owned solely by us. Feedback used for model improvement is decoupled

from your identity and from Customer Document content to the extent that does not

defeat its evaluative value.

7. Acceptable Use

You will not: (a) reverse engineer, scrape, or attempt to extract the Service's

models, checklists, or calibration data; (b) resell or sublicense the Service, or

present its output as independent engineering; (c) use it to circumvent

professional licensing obligations; (d) upload unlawful content or content you

lack the rights to; or (e) probe, overload, or disrupt the Service.

8. Accounts and Security

You are responsible for your credentials and API keys and for activity under your

account. Notify us of any unauthorized use. Accounts are per user; credentials may

not be shared across users without our explicit prior consent.

9. Fees, Subscriptions, and Billing

Paid plans are billed in advance on a recurring subscription basis. We may refuse

or limit service for any reason, including abuse or excessive use. Tier

definitions and any usage limits are as described at purchase.

10. Intellectual Property

We own the Service, including its software, checklists, corpus, models,

calibration datasets, and all derived artifacts. No rights are granted to you

except the limited right to use the Service under these Terms.

11. Confidentiality

Each party will protect the other's non-public information. We will apply

commercially reasonable measures to protect Customer Documents.

12. Privacy

Your use of the Service is subject to the PlanFlag Privacy Policy, which is

incorporated into these Terms by reference.

13. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY

KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR

PURPOSE, ACCURACY, COMPLETENESS, AND NON-INFRINGEMENT.

14. Limitation of Liability

To the maximum extent permitted by law, we are not liable for indirect,

incidental, consequential, special, or punitive damages, or for any

professional-liability, design-error, construction, or property damages arising

from use of or reliance on the Service. Our total aggregate liability is capped at

the fees you paid in the twelve months preceding the claim.

15. Indemnification

You will indemnify us against claims arising from your use of the Service, your

Customer Documents, or your violation of these Terms or applicable law.

16. Term and Termination

Either party may terminate in accordance with the plan terms. On termination,

your right to use the Service ends; provisions that by their nature should

survive, including intellectual property, the Feedback license, disclaimers, and

limitation of liability, survive.

17. Changes to These Terms

We may update these Terms; the current version is identified by the version string

above, and continued use after an update constitutes acceptance. We will notify

you of material changes.

18. Governing Law

These Terms are governed by the laws of the State of Missouri, without regard to

its conflict-of-laws rules. The contracting party is Computer Services

International, LLC.

19. Miscellaneous

These Terms are the entire agreement between you and us regarding the Service. If

any provision is held unenforceable, the remaining provisions remain in effect. No

waiver of any term is a waiver of any other term. We may assign these Terms; you

may not assign them without our consent.
