Terms of Service

Effective date: November 15, 2026

1. Who we are

These Terms of Service ("Terms") cover the Masterline HQ mobile apps, the Masterline HQ office website and this website (together, the "Service"). The Service is provided by Masterline Trades Software LLC, Charlotte, North Carolina ("we", "us"). By using the Service you agree to these Terms. If you use the Service for a company, you agree to them for that company.

2. Accounts

Company accounts for Masterline HQ are created by the company on this website. Your company administrator decides who has access and what each person can see. Keep your sign-in details private. You are responsible for activity under your account and for keeping your information accurate.

3. Plans, subscriptions and payments

Masterline HQ company plans and trade add-ons are billed by us through Stripe and renew each month or year until canceled. You can cancel from the Billing page in the office website; access continues to the end of the paid period. Prices do not include tax, which is added where required.

Bills from a service company to its own customers for repair or service work are between that company and its customer and are paid on that company's payment page.

4. Your data

Your company owns the business records it puts into the Service. You give us permission to store and process that data only to provide the Service, as described in our Privacy Policy. If you connect an accounting system such as QuickBooks or Xero, we only use that connection to send and read the records needed for the features you turn on, and you can disconnect it at any time in Settings. You can delete your account by following the steps on our Delete Account and Data page.

5. Tools, AI features and safety

Sizing tools, troubleshooting guides, code references, AI features and other guidance can be wrong or out of date, and local codes vary. They do not replace a qualified, licensed technician, the authority having jurisdiction, the manufacturer's instructions or your company's safety procedures. Always lock out and tag out equipment, de-energize circuits, and relieve pressure before working on it, and get the permits and inspections your area requires. You are responsible for decisions you make using the Service.

6. Acceptable use

Do not misuse the Service. For example, do not break the law with it, try to get into accounts or data that are not yours, interfere with how it works, upload harmful code, or copy, resell or reverse engineer it except as the law allows.

7. Changes and availability

We work to keep the Service running and improving, and we may add, change or remove features. We may suspend or end access for anyone who breaks these Terms. You can stop using the Service at any time.

8. Disclaimers

The Service is provided "as is" and "as available". To the extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement.

9. Limitation of liability

To the extent the law allows, we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue or data. Our total liability for any claim about the Service is limited to the amount you paid us for the Service in the 12 months before the claim.

10. Apple and Google

If you got an app from the Apple App Store or Google Play, these Terms are between you and us, not Apple or Google, and Apple and Google are not responsible for the app or its support. Apple and its subsidiaries are third-party beneficiaries of these Terms for apps downloaded from the App Store and may enforce them against you. Your use of the app must also follow the store's own terms.

11. Governing law

These Terms are governed by the laws of the State of North Carolina, without regard to its conflict of law rules. Nothing in these Terms takes away rights you have under consumer protection laws where you live.

12. Changes to these Terms

We may update these Terms. If a change is significant, we will tell you in the app or by email before it takes effect. Continuing to use the Service after the change means you accept the new Terms.
