Terms of Purchase & License Agreement

Last Updated: 10 December 2025

1. Acceptance of Terms

By purchasing, downloading, or using the Estate Agent Protocol ("the Asset"), you agree to be bound by these Terms. If you do not agree to these terms, do not purchase or use the Asset. These Terms constitute a binding legal agreement between you ("the Licensee") and HighSyntax ("the Licensor").

2. Nature of the Product

The Asset is a downloadable digital zip file containing proprietary prompt logic, license, and instructional text designed for use with third-party Large Language Models (LLMs). You acknowledge that:

  • This is a text-based protocol, not executable software application.
  • No cloud services, servers, or ongoing maintenance are provided by HighSyntax.
  • You are responsible for obtaining access to compatible third-party AI models (e.g., ChatGPT, Claude, Gemini, Deepseek).

3. Grant of License

Upon payment of the one-time license fee, HighSyntax grants you a non-exclusive, non-transferable, perpetual, worldwide license to use Version 1.4 of the Asset, subject to the following strict conditions:

3.1 Authorized Use

  • Single User: You may store and utilize the Asset on local LLMs installed on devices you solely operate, or on third-party AI accounts (e.g., ChatGPT, Claude) that you own.
  • Commercial Rights to Output: You own 100% of the text, narratives, and descriptions generated by the Protocol. You may use this output for real estate listings, marketing materials, and client communications royalty-free.
  • Modification: You may edit the Protocol code for your own personal workflow.

3.2 Prohibited Use

  • No Resale or Redistribution: You may not sell, rent, lease, sub-license, or distribute the Asset file itself to any third party.
  • No Team Sharing: You may not host the Asset on a shared company server, Intranet, or Slack channel for use by a team or agency. Each user requires a separate license.
  • No Reverse Engineering for Resale: You may not reverse-engineer the logic of the Protocol to build a competing "Real Estate AI" product or template.

3.3 Product Versioning

  • This license grants access specifically to Version 1.4. HighSyntax is under no obligation to provide free updates to future major releases (e.g., Version 2.0).
  • Future iterations may be sold as separate products and they will have their own legal terms.

4. Intellectual Property

The structure, logic, syntax, archetypes, ban list contained within the Protocol remain the sole intellectual property of HighSyntax. The purchase of a license does not transfer copyright ownership of the code to you.

5. Disclaimer of Warranties & Model Dependency

"As Is" Basis The Asset is provided "as is" without warranties of any kind. HighSyntax makes no guarantees regarding the specific quality, accuracy, or legal compliance of the real estate descriptions generated by the Asset.

  • AI Model Variance: The quality of the output is dependent on the capabilities of the local or third-party Large Language Model (LLM, e.g., OpenAI GPT-5, Claude 4.5 Sonnet, Google Gemini 3.0, DeepSeek R2, or any other AI model, free or paid) you use. You acknowledge that the models can hallucinate, invent non-existent property specs, or produce different results in varying degrees of quality. HighSyntax is not responsible for poor outputs generated by the AI.
  • Non-Deterministic Nature: Due to the probabilistic nature of AI, HighSyntax does not guarantee the consistency of the interview process or the output. The Protocol functions as a guide, not a hard-coded script.
  • No Business Results Guarantee: HighSyntax makes no representations or warranties that use of the Asset will increase your property sales rates, lead conversion, client engagement, revenue, or any other business outcome. Results depend on numerous factors outside the Protocol's control, including but not limited to: market conditions, property quality, pricing strategy, agent experience, and competitive landscape.

6. User Responsibility

You acknowledge that AI models can hallucinate or generate factually incorrect statements. You agree to act as the "Editor-in-Chief" and are solely responsible for verifying the accuracy of the generated listing narrative before publication. HighSyntax is not liable for misrepresentations, Fair Housing violations, or factual errors contained in your final listings.

7. Payment and Refunds

  • One-Time Payment: Access to the Asset requires a one-time license fee payment processed securely via our third-party payment processor (Stripe). We do not store financial data.
  • All Sales Final: Due to the nature of downloadable digital goods, which cannot be "returned," all sales are final. HighSyntax does not offer refunds, exchanges, or cancellations with the sole exception of:
    • Duplicate or erroneous charges (double billing)
    • Technical failure preventing download within 48 hours of purchase

8. Limitation of Liability

To the maximum extent permitted by law, HighSyntax shall not be liable for any direct, indirect, incidental, or consequential damages arising from the use of the Asset, including but not limited to loss of data, loss of revenue, loss of profits, loss of business opportunities, loss of real estate sales, or errors in listing descriptions. You acknowledge that the Protocol is a writing tool, not a business consulting service, and that HighSyntax has made no representations about business results. In no event shall HighSyntax's total liability exceed the amount paid by you for the Asset.

9. Governing Law and Jurisdiction

These Terms shall be governed by and construed in accordance with the laws of Hong Kong Special Administrative Region (HKSAR). Any disputes shall be subject to the exclusive jurisdiction of the courts of HKSAR.

10. Severability

If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary while preserving the remaining provisions.
