Terms of Service
Effective: July 21, 2026
Acceptance of Terms
These Terms of Service ("Terms") constitute a legally binding agreement between you ("User," "you," or "your") and Nyrus Corp. ("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.
Standard CATO accounts are currently available only to users in the United States. You may not create or use a standard account if you are located in the European Union or United Kingdom.
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 18 public scholarly sources, ClinicalTrials.gov, and patent databases, 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
- Full-text access for open-access research papers via PMC, BioRxiv, MedRxiv, and Europe PMC, with abstract fallback for paywalled content
- Support for 50+ file formats including SPSS, microbiome, genomics, and medical imaging data
CATO's AI models and underlying infrastructure are periodically upgraded to improve performance, accuracy, and reliability. Model versions may change without prior notice, and outputs may vary across model versions.
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.
Pay-as-you-go pricing varies by AI model tier and is published on the Pricing page. Advanced analysis modes may consume credits at higher rates than standard queries.
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.
Acceptable Use
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
- Upload, transmit, or process Protected Health Information (PHI) as defined under HIPAA unless you are on an Enterprise plan with a signed Business Associate Agreement (BAA)
- Upload, transmit, or process other identifiable consumer health, genetic, biometric, or patient-level data through a standard account
- Attempt to gain unauthorized access to any part of the Service, other users' accounts, or our systems and infrastructure
- Reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code of any part of the Service
- Use the Service to develop competing products or services
- Interfere with or disrupt the integrity or performance of the Service
- Use automated means (bots, scrapers, crawlers) to access the Service except through our published API
- Resell, sublicense, or commercially exploit the Service without our prior written consent
- Upload content that is unlawful, harmful, threatening, abusive, defamatory, or otherwise objectionable
Violation of these restrictions may result in immediate suspension or termination of your account.
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 as necessary to provide, secure, evaluate, and improve the Service, subject to these Terms and our Privacy Policy.
Data Handling
User files and project artifacts are stored in Google Cloud object storage. When an analysis needs a file, a trusted controller stages a temporary copy into an isolated sandbox. Sandbox pods do not receive cloud-storage credentials, application secrets, or mounted object storage. The temporary copy is removed when the sandbox pod or session is cleaned up, subject to operational recovery and security processes outside the sandbox.
Uploading a file does not, by itself, copy the full raw file into an agent trajectory. If CATO reads or processes the file, excerpts, selected rows, summaries, tool results, generated outputs, or other content surfaced to the agent may be recorded in the applicable trajectory. For full details, please refer to our Privacy Policy and Data Processing notice.
Service Trajectories, Safety, and Model Improvement
During and after the beta period, CATO records agent trajectories. A trajectory may include your prompts, model responses, tool calls and results, generated code, citations, reviewer results, execution metadata, safety signals, and User Content that appears in those records. We use these records to operate and restore workflows, reproduce failures, evaluate scientific performance, prevent misuse, enforce our policies, investigate security events, create curated evaluation and training data, and improve or train CATO models and agent systems.
Operational trajectories and training-approved trajectories are kept in separate Google Cloud storage boundaries. Production systems may create operational records but cannot read them back for training. A restricted cleaning and approval pipeline must read an operational record, apply the applicable review and minimization controls, and create a separate approved copy before a training system can access it. Training systems have read access only to the training-approved store.
By accepting these Terms and using CATO, you authorize this processing. Do not submit PHI, other identifiable health data, confidential information, unpublished data, or third-party content unless the applicable CATO plan permits it and you are authorized to use it for these purposes. You may contact contact@nyrus.ai to request that identifiable records no longer be selected for future model-improvement datasets. A request does not affect processing completed before it is implemented or records that must be retained for security, fraud prevention, policy enforcement, disputes, or legal obligations.
We do not authorize third-party model providers to use your User Content to train their own models. Where supported, CATO uses zero-data-retention inference paths. This restriction does not prevent Nyrus from using trajectories to improve CATO and its other offerings as described above.
Data Portability & Deletion
You may export or delete User Content through the Service. Deleting a conversation or project removes the primary application copy, but it may not immediately remove copies from security, diagnostic, trajectory, or backup systems. Contact contact@nyrus.ai for a verified request to delete identifiable trajectory data. Deidentified or aggregated evaluation and training data may be retained where permitted by law. Data already included in a training run that is underway, and improvements already incorporated into trained model weights, cannot generally be traced back and selectively reversed.
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
- AI capabilities are periodically expanded with new analysis libraries and tools. Users should validate all outputs, especially when using newly available analytical methods
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 Corp. 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.
Third-Party Services
CATO integrates with third-party services to deliver its functionality. Current hosted-service providers include Fireworks AI and Anthropic for AI inference, Railway for application hosting, PostgreSQL metadata, Redis, Temporal workflow state, service logs, and a transient trajectory delivery spool, Google Cloud for authoritative user-file, artifact, operational-trajectory, and training-approved-trajectory object storage and sandbox execution, Sentry for error monitoring, Stripe for billing, and Resend for email delivery. The Privacy Policy identifies the function, data categories, and retention posture for each provider. The Literature Intelligence feature transmits your search queries to external academic databases and APIs, including PubMed, PMC, Europe PMC, Unpaywall, CORE, Crossref, OpenAlex, DataCite, Semantic Scholar, arXiv, bioRxiv, medRxiv, ChemRxiv, SSRN, Research Square, OSF, Zenodo, HAL, ClinicalTrials.gov, and patent databases. By using CATO, you acknowledge that your data may be processed by these providers in accordance with their respective terms.
Third-party AI models may be used for specialized analytical tasks such as research-mode reasoning, literature planning and writing, reviewer operations, multi-agent delegation, and code generation or repair. By using CATO, you acknowledge that the prompt and the context needed for the selected operation may be processed by these partner models.
Sandboxed analyses may make outbound requests to public HTTP and HTTPS destinations for package installation, scientific data retrieval, or code that you request or approve. CATO blocks sandbox access to internal cloud networks and metadata services, but public destinations are not limited to the named providers above. You are responsible for ensuring that requested destinations and data transfers are appropriate for your data.
Contracted service providers process data for CATO under their applicable agreements. Public research services operate under their own terms and policies. Review our Privacy Policy, Data Processing notice, and Subprocessors page for details about how data is handled.
