Terms of Service

1. Who can use Stringlyne

You must be at least 18 years old and authorized to enter into contracts on behalf of any business you list. By using the Service you represent that all information you provide is accurate and that you have the right to use it.

2. Account responsibility

You are responsible for keeping your login credentials confidential and for all activity under your account. Notify us immediately if you suspect unauthorized access.

3. Contractor responsibilities

• You are solely responsible for the accuracy of every proposal you send. Stringlyne's AI generates a draft based on your inputs; you must review and edit it before sending.
• You are responsible for compliance with all applicable building codes, permits, licensing, insurance, and labor laws.
• You are responsible for fulfilling the work described in any signed proposal and for honoring any payment terms you set.
• You will not use Stringlyne to send misleading, fraudulent, or unsolicited communications.

4. Homeowner acknowledgments

When you sign a proposal via a Stringlyne link, you are entering a binding agreement with the contractor — not with Stringlyne. Stringlyne acts only as the platform that transmits the proposal, captures your e-signature, and forwards your deposit to the contractor via Stripe. Stringlyne is not a party to the construction contract and is not liable for the contractor's performance.

5. AI-generated content

Stringlyne uses large language models (currently Anthropic Claude) to generate proposal drafts. Generated content may contain errors, including incorrect material pricing, incorrect span calculations, or non-compliant code references. You must verify all generated content before sending it to a customer or relying on it for construction purposes. Stringlyne disclaims liability for losses arising from reliance on AI-generated content without review.

6. Payments

Payments from homeowners are processed by Stripe Connect. By accepting payments through Stringlyne you also agree to Stripe's Connected Account Agreement. We do not hold, transfer, or have custody of funds — Stripe transfers deposits directly to your connected bank account.

7. Acceptable use

You agree not to:

• Reverse engineer, decompile, or attempt to extract source code from the app.
• Use the Service to harass, defraud, or harm any person.
• Submit content that infringes the intellectual property of others.
• Use the Service to send spam or unsolicited communications.
• Attempt to circumvent rate limits, authentication, or access controls.
• Resell or commercially redistribute the Service without our written consent.

8. Intellectual property

Stringlyne and its design, code, and content are owned by us. We grant you a limited, non-exclusive, non-transferable license to use the Service for your business operations. You retain ownership of the content you submit (walkthroughs, photos, proposal content).

9. Termination

You may cancel your account at any time from the Settings screen or by emailing support@stringlyne.app. We may suspend or terminate your account if you breach these Terms, with reasonable notice unless the breach involves fraud, abuse, or legal noncompliance, in which case we may act immediately.

10. Disclaimers

The Service is provided "as is" without warranties of any kind, express or implied. We do not warrant uninterrupted or error-free operation, accuracy of generated content, or compatibility with any specific use case.

11. Limitation of liability

To the maximum extent permitted by law, Stringlyne's total liability arising out of or relating to the Service shall not exceed the greater of (a) the amount you paid us in the 12 months preceding the claim, or (b) one hundred U.S. dollars ($100). We are not liable for indirect, incidental, consequential, or punitive damages.

12. Indemnification

You agree to indemnify and hold Stringlyne harmless from claims arising out of (a) your use of the Service in violation of these Terms, (b) work you perform or fail to perform under proposals generated using the Service, or (c) your violation of any third-party right.

13. Governing law

These Terms are governed by the laws of the State of North Carolina, United States, without regard to its conflict-of-laws principles. Any dispute will be resolved in the state or federal courts located in Wake County, North Carolina, and you consent to personal jurisdiction there.

14. Changes

We may update these Terms from time to time. Material changes will be announced via email and in the app at least 14 days before they take effect. Continued use after the effective date constitutes acceptance.
