Terms of Service

Effective date: November 13, 2026

1. Who we are

These Terms of Service ("Terms") cover the TradeSystem HQ and TradeSystem Connect mobile apps, the TradeSystem 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 TradeSystem HQ are created by the company on this website. Your company administrator decides who has access and what each person can see. TradeSystem Connect can be used without an account; if you create one, 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

TradeSystem HQ company plans 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.

TradeSystem Connect Pro and Pro + AI Tech are auto-renewing subscriptions sold through the Apple App Store or Google Play. Payment is charged to your Apple or Google account when you confirm the purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You manage or cancel these subscriptions in your App Store or Google Play account settings. Refunds for them follow Apple's or Google's refund policies.

Bills from your own plumbing or electrical service company for repair or service work are between you and that company and are paid on that company's payment page.

4. Your data

Your company owns the business records it puts into the Service, and you own what you add as a Connect user. You give us permission to store and process that data only to provide the Service, as described in our Privacy Policy. You can delete your account in the app under Account or by following the steps on our Delete Account and Data page.

5. Tools, codes, AI features and safety

Code references, sizing tools (such as wire, fuse, breaker and pipe sizing), fix-it guides, AI Tech and other AI features give guidance only. They can be wrong or out of date, and local codes and amendments vary. They do not replace a licensed, qualified plumber or electrician, the authority having jurisdiction, the manufacturer's instructions or your company's safety procedures. Always de-energize and lock out circuits before electrical work, shut off and relieve water and gas before plumbing work, and get the permits and inspections your area requires. Do not do work you are not trained or licensed to do. 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.
