Terms of Service

1. Acceptance of Terms

By accessing or using Opzun ("the Service"), available at opzun.com, you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.

2. Description of Service

Opzun is a free options strategy visualization and sharing tool. It allows users to construct options strategies, view theoretical payoff diagrams, and share strategies via unique URLs ("Zuns"). The Service does not require user accounts and is provided at no cost.

3. No Warranty

The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or free of harmful components. Options data displayed is delayed and may be inaccurate. All calculations are theoretical estimates and should not be relied upon for trading decisions.

4. User-Generated Content

When you create and share a Zun, you retain ownership of any original content you contribute (such as strategy names and notes). By sharing a Zun, you grant Opzun a non-exclusive, worldwide, royalty-free license to store, display, and distribute that content through the Service. Shared Zuns are publicly accessible to anyone with the link.

5. Acceptable Use

You agree not to:

• Use the Service for any illegal purpose or in violation of any applicable laws
• Attempt to interfere with, compromise, or disrupt the Service or its infrastructure
• Abuse the Service through automated scraping, excessive API calls, or denial-of-service attacks
• Share content that is defamatory, obscene, fraudulent, or otherwise objectionable
• Misrepresent the Service or its outputs as professional financial advice

6. Content Removal

We reserve the right to remove any shared Zun or content at our sole discretion, for any reason, without prior notice. This includes but is not limited to content that violates these Terms, is reported as abusive, or places undue burden on the Service.

7. Limitation of Liability

To the maximum extent permitted by applicable law, Opzun and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses resulting from: (a) your use of or inability to use the Service; (b) any errors, inaccuracies, or omissions in the data or calculations provided; (c) any trading decisions made based on information from the Service; or (d) any unauthorized access to or alteration of your content.

8. Third-Party Services

The Service relies on third-party data providers and infrastructure services including CBOE, Finnhub, Yahoo Finance, Supabase, Vercel, and Upstash. We are not responsible for the availability, accuracy, or reliability of these third-party services.

9. Changes to Terms

We may update these Terms at any time. Changes take effect when posted to this page. Your continued use of the Service after changes are posted constitutes acceptance of the revised Terms. We encourage you to review this page periodically.

10. Governing Law

These Terms shall be governed by and construed in accordance with applicable law, without regard to conflict of law principles.
