"Account" means your registered Chion account.

"Content" means any data, queries, database schemas, SQL statements, visualizations, or other materials you submit to, generate through, or access via the Service.

"Generated Output" means SQL queries, D3.js visualizations, narrative analytics, and any other content produced by the Service's AI-powered pipeline in response to your inputs.

"Data Source" means any third-party database or data system you connect to the Service via credentials or connection strings.

"Credits" means the unit of consumption used to meter access to pipeline features, as defined by your subscription plan.

2.1. You must be at least 18 years old and capable of forming a binding contract to use the Service.

2.2. You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. You agree to notify us immediately of any unauthorized use.

2.3. You may not create multiple accounts to circumvent usage limits, rate limits, or credit caps.

3.1. Chion is an AI-native analytics platform that transforms natural language queries into SQL and data visualizations. The Service connects to your databases, processes queries through large language model (LLM) pipelines, and returns structured analytical outputs.

3.2. The Service uses third-party AI models — including Anthropic Claude, OpenAI, Google Gemini, and Mistral — to process natural language inputs and generate SQL and analytical content. Your queries are transmitted to these third-party providers for processing. Model selection is automatic in Quick Start mode and fully configurable in Custom Setup. See Section 10 (Third-Party Services) for details.

3.2a. No Model Training on Your Data. Chion accesses all LLM providers exclusively through paid commercial API tiers. Under the standard commercial terms of these providers, your queries and generated outputs are not used to train, improve, or fine-tune any third-party AI models.† However, all providers retain prompts and responses for limited periods (typically 30–55 days) solely for abuse monitoring, safety enforcement, and compliance with legal obligations. See Section 10 for provider-specific details.

3.3. The Service stores database connection credentials using AES-GCM encryption with time-limited in-memory decryption. Plaintext credentials are never logged, persisted to disk, or retained beyond the active session window.

3.4. Data Sampling. To power entity resolution and semantic understanding, the Service samples a limited number of representative values from categorical columns in your connected data sources. These samples — such as frequent category values, dimension labels, or entity names — are used to improve query accuracy (e.g., matching a natural language reference like "Q3 revenue" to the actual column value "2024-Q3" in your data). Sampled values are stored in your tenant-isolated space, protected by row-level security, and are never shared with other users or used for any purpose outside your account. You may delete all sampled data at any time through the Service's account settings.

3.5. Document Processing. When you connect a document source (such as Google Drive), the Service processes document content to extract structure, summaries, keywords, and temporal references for analytical use. Document content is stored in your tenant-isolated space, protected by row-level security, and processed through the same AI providers listed in Section 10. You control which documents are approved for processing, and you may delete all document data at any time through the Service's account settings.

5.1. Your Data. You retain all ownership rights in the data, schemas, queries, and other content you provide to the Service ("Your Data"). We claim no ownership over Your Data.

5.2. Generated Output. You own the Generated Output produced by the Service in response to your inputs, including SQL queries, visualizations, and narrative analytics. We retain no rights to your Generated Output except as necessary to provide the Service.

5.3. Platform IP. We retain all rights in the Service itself, including but not limited to: the pipeline architecture, prompt templates, semantic layer logic, UI/UX design, and underlying code. Nothing in these Terms grants you rights to our proprietary technology.

5.4. Feedback. If you provide feedback, suggestions, or ideas about the Service, you grant us a non-exclusive, royalty-free, perpetual license to use that feedback for any purpose without obligation to you.

5.5. Open-Source Components. The Service incorporates open-source software components, including D3.js (ISC License, Copyright 2010–2023 Mike Bostock) for data visualization rendering. These components are provided under their respective open-source licenses, which are made available at chion.ai/licenses. In the event of any conflict between these Terms and the license terms of any open-source component, the open-source license terms shall govern with respect to that component.

You agree not to use the Service to:

6.1. Execute, generate, or attempt to generate SQL that intentionally damages, corrupts, or destroys data in any connected database, or that is designed to exfiltrate data beyond what is necessary for your authorized analytical purposes.

6.2. Connect databases containing data you do not have authorization to access or analyze.

6.3. Attempt to inject malicious content into prompts, queries, or pipeline inputs for the purpose of manipulating the AI system's behavior, bypassing safety controls, or extracting proprietary system prompts or pipeline logic.

6.4. Use the Service in connection with regulated industries (healthcare, financial services, legal) without independently validating all Generated Output against applicable regulatory requirements. The Service does not provide compliance guarantees for regulated use cases.

6.5. Reverse-engineer, decompile, or attempt to extract the source code, prompt templates, or pipeline architecture of the Service.

6.6. Use automated scripts, bots, or other tools to access the Service in a manner that exceeds the published rate limits or circumvents usage controls.

6.7. Resell, sublicense, or redistribute access to the Service or its Generated Output as a competing analytics product.

6.8. Use the Service for any purpose that violates applicable local, state, national, or international law or regulation.

6.9. Access the Service from, or provide access to the Service in, any U.S. embargoed country or region, or to any person or entity on the U.S. Treasury Department's Specially Designated Nationals list, the U.S. Department of Commerce Denied Persons or Entity Lists, or any other applicable restricted party list. You represent and warrant that you are not located in any such country and are not on any such list.

6.10. Store, process, or transmit protected health information (as defined by HIPAA) through the Service without a separately executed Business Associate Agreement. The Service is not HIPAA-compliant by default.

7.1. AI-Generated Content. The Service generates SQL and analytical content using large language models. Generated Output may contain errors, inaccuracies, suboptimal query patterns, or incorrect analytical conclusions — including material inaccuracies that may appear accurate due to their level of detail or specificity. Factual assertions in Generated Output should not be relied upon without independently checking their accuracy, as they may be false, incomplete, misleading, or not reflective of recent events or information. You are solely responsible for reviewing, validating, and testing all Generated SQL before executing it against any database, especially production systems.

7.2. No Warranty of Correctness. We do not warrant that Generated Output will be accurate, complete, error-free, or suitable for any particular purpose. The Service is a productivity tool, not a substitute for qualified data engineering or analytical judgment.

7.3. Execution Risk. You acknowledge that executing AI-generated SQL against a live database carries inherent risk, including but not limited to data loss, corruption, or unintended modification. We strongly recommend using read-only database connections and testing queries in non-production environments before executing them against production data.

7.4. No Professional Advice. Generated Output does not constitute financial, legal, medical, or other professional advice. You should not rely on it as such.

8.1. Credential Storage. Database connection credentials are encrypted at rest using AES-GCM encryption. Credentials are decrypted in-memory only during active pipeline operations and are subject to time-to-live (TTL) expiration. We never log, persist, or retain plaintext credentials.

8.2. Tenant Isolation. Your data is logically isolated from other users' data through row-level security (RLS) policies applied at the database layer. Each user's data sources, queries, and outputs are accessible only to their authenticated account.

8.3. Transmission Security. All data in transit between your browser and the Service, and between the Service and connected databases, is encrypted using TLS 1.2 or higher.

8.4. Your Responsibility. You are responsible for the security of your database credentials and for ensuring that the database user you connect has appropriate permission scoping (e.g., read-only access). We recommend granting the minimum privileges necessary for your analytical needs.

9.1. Our collection, use, and processing of personal data is governed by our Privacy Policy, which is incorporated into these Terms by reference.

9.2. We collect limited account information (email address, name, and company name if provided) for authentication, billing, and service communications. We do not collect personally identifiable information from your connected databases. The data transmitted to AI providers for query processing consists of structural metadata, semantic labels, and limited representative samples — never full row exports, credentials, or bulk data.

9.2a. Data transmitted to third-party AI providers may be processed and temporarily stored in any country in which those providers or their agents maintain facilities. By using the Service, you consent to this transfer and processing. We enter into data processing agreements with all sub-processors to ensure appropriate safeguards are in place.

9.3. We collect usage telemetry (pipeline execution counts, token consumption, feature usage) for billing, performance optimization, and product improvement. This data is aggregated and anonymized where feasible.

9.4. We retain AI inference records (prompts submitted to and responses received from AI providers) in your tenant-isolated space for the purpose of maintaining your semantic layer and session continuity. These records are protected by the same row-level security policies as all other user data and are included in data deletion requests.

9.5. The Service generates mathematical representations (vector embeddings) of your data source metadata and document content for semantic search and entity resolution. These embeddings are derived metadata, not full content reproductions — they contain only statistical representations used for retrieval. They are stored in your tenant-isolated space and deleted when you delete the associated data.

10.1. The Service relies on the following third-party services ("Sub-Processors") to operate:

10.2. We may update Sub-Processors with 30 days' advance notice. Material changes to Sub-Processors will be communicated via email to your registered account.

10.3. We enter into appropriate data processing agreements with all Sub-Processors and require them to maintain security standards consistent with industry best practices.

† Chion is actively negotiating dedicated data processing agreements (DPAs) with each LLM provider marked above to formalize contractual prohibitions against model training on customer content. Until these agreements are executed, the no-training guarantees described in this section are governed by each provider's standard commercial API terms, which prohibit the use of paid API inputs and outputs for model training. We will update this section as agreements are finalized.

11.1. Disclaimer of Warranties. THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE."

13.2. Binding Arbitration. Any dispute not resolved informally shall be resolved by binding arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules. The arbitration shall take place in Broward County, Florida. The arbitrator's decision shall be final and binding.

13.3. Class Action Waiver. YOU AND DAGNOSTICS LLC DBA CHION AGREE THAT EACH PARTY MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING.

13.4. Small Claims Exception. Either party may bring qualifying claims in small claims court in Broward County, Florida.

13.5. Governing Law. These Terms are governed by the laws of the State of Florida, without regard to conflict of law principles.

13.6. Export Controls. The Service relies on third-party AI services subject to U.S. export control laws and regulations. You may not use, export, or re-export the Service except as authorized by United States law, the laws of the jurisdiction in which the Service was accessed, and any other applicable laws and regulations. In particular, the Service may not be exported or re-exported into any U.S. embargoed countries or to anyone on the U.S. Treasury Department's Specially Designated Nationals list or the U.S. Department of Commerce Denied Persons or Entity List.
