Terms of Service
Effective: February 19, 2026
Acceptance of Terms
These Terms of Service ("Terms") constitute a legally binding agreement between you ("User," "you," or "your") and Nyrus Inc. ("Nyrus," "we," "us," or "our"), the operator of the Cato platform ("Cato" or the "Service").
By creating an account, accessing, or using Cato, you acknowledge that you have read, understood, and agree to be bound by these Terms, our Privacy Policy, and our Usage Policy. If you do not agree to these Terms, you must not use the Service.
If you are using Cato on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms.
Description of Service
Cato is an AI-powered data analysis platform designed for biomedical and life sciences researchers. The Service provides:
- Conversational AI assistance for data analysis and statistical modeling
- Sandboxed code execution environments for Python and R
- Literature Intelligence: multi-source academic search across PubMed, BioRxiv, arXiv, ClinicalTrials.gov, patent databases, and OpenAlex, with AI-powered evidence extraction, citation network analysis, and document generation
- Interactive data visualizations and publication-ready figures
- Dataset management, organization, and cloud storage integration
- Access to curated biomedical databases and specialized analysis tools
We reserve the right to modify, suspend, or discontinue any aspect of the Service at any time, with or without notice. We will make commercially reasonable efforts to notify users of material changes in advance.
Account Registration & Security
To use Cato, you must create an account by providing accurate and complete information. You are responsible for:
- Maintaining the confidentiality of your login credentials
- All activity that occurs under your account
- Notifying us immediately of any unauthorized access or use of your account
- Ensuring that your account information remains accurate and up to date
You must be at least 18 years of age or the age of majority in your jurisdiction to create an account. We reserve the right to suspend or terminate accounts that violate these Terms or that we reasonably believe are being used fraudulently.
Subscription Plans & Billing
Plans & Pricing
Cato offers multiple subscription tiers, including free and paid plans. Details of each plan, including features, usage limits, and pricing, are available on our pricing page. We reserve the right to change our pricing at any time, with 30 days' notice to existing subscribers before changes take effect on their next billing cycle.
Free Trials
Paid plans may include a free trial period. At the end of the trial, you will be automatically billed at the applicable rate unless you cancel before the trial expires. You may cancel your trial at any time through your account settings.
Billing & Payment
Paid subscriptions are billed in advance on a monthly recurring basis. Pay-as-you-go usage is billed in arrears based on actual consumption. All payments are processed through Stripe. By subscribing to a paid plan, you authorize us to charge the payment method on file for all applicable fees.
Cancellation & Refunds
You may cancel your subscription at any time through your account settings. Cancellation takes effect at the end of your current billing period, and you will retain access to paid features until that date. We do not provide prorated refunds for partial billing periods. If you believe you have been billed in error, please contact us within 30 days of the charge.

You agree to use Cato only for lawful purposes and in compliance with these Terms. You may not:
- Use the Service to violate any applicable law, regulation, or third-party right

User Content & Data
Ownership
You retain all rights, title, and interest in the data, datasets, files, and other content you upload to or create within Cato ("User Content"). We do not claim ownership of your User Content.
License Grant
By uploading User Content, you grant us a limited, non-exclusive, worldwide license to store, process, transmit, and display your User Content solely as necessary to provide and improve the Service. This license terminates when you delete your User Content or close your account.
Data Handling
Your datasets are processed within isolated, sandboxed environments. Code execution occurs in ephemeral containers that are destroyed after each session. We do not use your User Content to train AI models. For full details on how we handle your data, please refer to our Privacy Policy.
Data Portability & Deletion
You may export or delete your User Content at any time through the Service. Upon account deletion, we will remove your User Content from our active systems within 30 days. Backup copies may persist for up to 90 days before being permanently purged.
AI-Generated Output
Cato uses artificial intelligence models to generate analysis results, code, visualizations, and text ("AI Output"). You acknowledge and agree that:
- AI Output may contain errors, inaccuracies, or biases and should not be relied upon as the sole basis for scientific conclusions, clinical decisions, or regulatory submissions
- You are solely responsible for reviewing, validating, and verifying all AI Output before use in research, publications, or any downstream applications
- AI Output does not constitute medical, clinical, legal, or professional advice of any kind
- Statistical results, p-values, and analytical conclusions generated by Cato must be independently verified using established scientific methodology
- AI Output may vary between sessions even for identical inputs, and reproducibility is not guaranteed
You are responsible for ensuring that your use of AI Output complies with the publication guidelines of any journals, institutions, or funding bodies to which you submit work.
Intellectual Property
Our Property
The Service, including its design, architecture, source code, documentation, branding, and all associated intellectual property rights, is and remains the exclusive property of Nyrus Inc. These Terms do not grant you any right, title, or interest in the Service except the limited right to use it in accordance with these Terms.
Your Output
Subject to the rights of any underlying third-party models, you retain ownership of the analyses, visualizations, reports, and other outputs you create using the Service. You are free to use, publish, and distribute these outputs without restriction, provided you comply with applicable laws and institutional policies.
Feedback
If you provide feedback, suggestions, or ideas about the Service, you grant us a perpetual, irrevocable, royalty-free license to use that feedback for any purpose, including to improve the Service, without any obligation to you.
