Terms of Use

1. Agreement and eligibility

These Terms of Use are an agreement between you and MarginCrew LLC, a Michigan limited liability company that offers MarginBrace ("Company," "we," "us," or "our"). By accessing or using the MarginBrace website or calculator (the "Service"), you agree to these terms and our Privacy Policy. If you do not agree, do not use the Service.

The Service is intended for adults using it for business or professional planning. You must be at least 18 years old and legally capable of entering this agreement.

2. The current Service

MarginBrace provides a free, browser-based calculator that estimates job prices, costs, payment fees, gross profit, and gross margin from numbers you enter. The free calculator does not require an account or save its inputs to Company servers. The optional Pro beta requires sign-in and can save business settings, jobs, price-book items, margin history, and estimate information.

The current Service does not accept payments. Prices shown for a future paid Pro plan are informational only and are not an offer, preorder, or commitment to release paid features at a particular price or time.

3. Permission to use the Service

Subject to these terms, the Company grants you a limited, revocable, nonexclusive, nontransferable right to use the Service for your own lawful business planning. You may print or copy results for your own records and customer discussions.

4. Your numbers and decisions

Results depend entirely on your inputs and assumptions. You are responsible for verifying labor burden, material prices, overhead, taxes, fees, permits, contract requirements, market conditions, and job-specific risk before giving a quote or entering a contract.

MarginBrace is a planning aid, not accounting, tax, legal, financial, engineering, insurance, estimating, or other professional advice. It does not guarantee a job’s final cost, customer acceptance, cash flow, or profit. Read the Calculator Disclaimer for additional limitations.

5. Your calculator inputs

In the free calculator, values are processed in your browser and are not submitted to or saved by the Company. When you intentionally save a Pro job, the information is stored so it can be returned to the signed-in account. You represent that you have a lawful business reason to enter customer information and will limit it to what is reasonably needed for the estimate. Do not enter card data, Social Security numbers, medical information, or other unnecessary sensitive data.

6. Acceptable use

You may not:

• use the Service for an unlawful, fraudulent, or deceptive purpose;
• interfere with, overload, damage, or bypass the Service’s security;
• use automated means to scrape or extract the Service at unreasonable volume;
• introduce malware or attempt unauthorized access to systems or data;
• misrepresent that MarginBrace or the Company prepared, approved, or guarantees your customer quote; or
• copy or resell the Service itself except as permitted by law or written agreement.

7. Ownership

The Company and its licensors own the Service, including its software, design, text, graphics, branding, and other content, subject to applicable third-party and open-source licenses. These terms do not transfer ownership to you. You retain ownership of information you create outside the Service and of your own business records.

8. Availability and changes

We may correct, change, suspend, or discontinue any part of the Service. We do not promise uninterrupted availability, permanent storage, or compatibility with every browser or device. Pro beta is a preview and may change. Keep your own copy of any estimate or record that is essential to your business.

9. Disclaimer of warranties

To the maximum extent permitted by law, the Service is provided "as is" and "as available." The Company disclaims implied warranties of merchantability, fitness for a particular purpose, title, and noninfringement. We do not warrant that any result is complete, accurate for your circumstances, error-free, or suitable as a final bid or contract price.

10. Limitation of liability

To the maximum extent permitted by law, MarginCrew LLC and its member, personnel, and service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profit, revenue, data, opportunity, goodwill, or business, arising from the Service or your pricing decisions.

To the maximum extent permitted by law, their total liability for all claims related to the Service will not exceed the greater of $100 or the amount you paid the Company for the Service during the 12 months before the event giving rise to the claim. Some laws do not allow certain exclusions or limits, so those provisions apply only to the extent allowed by applicable law.

11. Indemnification

To the extent permitted by law, you will defend and indemnify MarginCrew LLC from third-party claims, damages, and reasonable costs arising from your unlawful misuse of the Service, your violation of these terms, or customer-facing claims or contracts you create using your results. This section does not require indemnification for the Company’s own unlawful conduct.

12. Governing law

Michigan law governs these terms, without regard to conflict-of-law rules. Any court proceeding must be brought in a state or federal court with jurisdiction over Oakland County, Michigan, unless applicable law requires another forum. Mandatory rights that cannot lawfully be waived remain unaffected.

13. Changes and general terms

We may update these terms by posting a revised version and changing the effective date. Continued use after an update means you accept the revised terms. If one provision is unenforceable, the remaining terms remain in effect. These terms, the Privacy Policy, and the Calculator Disclaimer are the entire agreement governing the current Service.
