1. Acceptance of Terms

BY ACCESSING OR USING AGRSTAK, YOU AGREE TO BE BOUND BY THESE TERMS OF SERVICE AND OUR PRIVACY POLICY. IF YOU DO NOT AGREE, DO NOT USE THE PLATFORM.

These Terms of Service ("Terms") constitute a legally binding agreement between you and NumeriXGPT LLC ("we," "us," "our"), a Georgia Limited Liability Company, governing your access to and use of the AgrStak platform, including all calculator storefronts, the AgrStak Chat Widget (ACW), and related services hosted at numerixgpt.com and associated domains (collectively, the "Platform").

These Terms replace and supersede the prior Terms of Service dated December 2024. If you are an institutional partner, your use is also governed by your executed Data Sharing Agreement (DSA), which supplements these Terms.

2. Description of Service

AgrStak is an AI-powered agricultural decision support platform operated by NumeriXGPT LLC. The Platform transforms USDA agricultural research into accessible calculator tools for farmers, researchers, and agricultural professionals.

The Platform currently includes:

  • 431 agricultural calculator models across 14 specialized categories, built on USDA-ARS research
  • 14 calculator storefronts covering domains including soil science, plant breeding, animal science, food science, nutrition, and agricultural economics
  • AgrStak Chat Widget (ACW) — an AI-powered assistant on each calculator page, powered by the Anthropic Claude API
  • Research model registry — traceable sourcing and versioning for all calculator models
  • Institutional partnership services — data sharing and model development for USDA research institutions and extension services
Agricultural Decision Disclaimer

AgrStak calculators are decision support tools based on USDA research models. Outputs should be validated with a qualified agronomist, extension agent, or agricultural professional before making farm management, financial, or operational decisions. AgrStak does not provide professional agronomic, financial, or legal advice.

3. Accounts & Access

Some features of AgrStak may require you to create an account. When creating an account you agree to: (a) provide accurate and complete information; (b) maintain the security of your password; (c) promptly update your account information if it changes; and (d) accept responsibility for all activity that occurs under your account.

3.2 Account Security

You are responsible for maintaining the confidentiality of your account credentials. Notify us immediately at [email protected] if you believe your account has been compromised. We are not liable for losses caused by unauthorized use of your account.

3.3 Eligibility

You must be at least 18 years of age to create an account or use AgrStak services. By using the Platform you represent that you meet this requirement. AgrStak is designed for agricultural professionals, researchers, and producers — not for general consumer use.

  • Use the Platform to develop competing products or services during the Term and for two (2) years following termination
  • Transmit through the Platform any content that is unlawful, harmful, fraudulent, or violates the rights of others

We reserve the right to suspend or terminate access to any user who violates these acceptable use provisions, with or without notice.

5. Calculator Tools & Research Models

5.1 Nature of Calculator Outputs

AgrStak's 431 calculator models are built on published USDA agricultural research. All outputs are intended as decision support tools only. They are not a substitute for professional agronomic advice, soil testing, extension services, or qualified expert consultation.

5.2 Accuracy & Model Updates

While we strive to keep all models current with the latest USDA research, agricultural science evolves and models may not reflect the most recent findings at all times. We maintain a versioning and validation cycle for all models but cannot guarantee that outputs will be accurate for every specific geographic, soil, crop, or climate condition.

5.3 Calculator Input Data

Input values you enter into AgrStak calculators are processed in your browser session and are never stored on AgrStak servers. See our Privacy Policy for full details. You are responsible for the accuracy of data you input into calculators.

5.4 Export & Use of Outputs

You may export and use calculator outputs for your own farm management, research, or educational purposes. Any publication, commercial use, or redistribution of AgrStak outputs must include attribution to AgrStak and the underlying USDA research source. You may not commercialize AgrStak outputs without a separate written licensing agreement.

6. AI & Chat Feature Terms

6.1 AI-Powered Assistance

The AgrStak Chat Widget (ACW) is powered by the Anthropic Claude API. By using the chat feature, you acknowledge that your messages are processed by Anthropic's systems, subject to Anthropic's Terms of Service and Privacy Policy.

6.2 AI Output Limitations

AI-generated responses from the ACW are provided for informational and guidance purposes only. You agree that:

  • AI outputs may contain errors, inaccuracies, or omissions and should be independently verified
  • AgrStak is not responsible for decisions made based on AI chat outputs
  • AI responses do not constitute professional agronomic, legal, financial, or medical advice
  • You will not rely solely on AI outputs for significant farm management or financial decisions

6.3 Prohibited Chat Uses

You agree not to use the ACW to:

  • Attempt to extract, reverse engineer, or probe the underlying AI model or its training data
  • Submit personally identifiable information, financial data, or other sensitive personal details
  • Generate content unrelated to agricultural decision support
  • Attempt to circumvent, manipulate, or jailbreak the AI system
AI Transparency

AgrStak does not use your chat messages to train AI models. Our AI governance principles, including no-training commitments and hallucination monitoring, are publicly documented in our Data Governance Framework.
