1. Products Covered

This Privacy Policy covers:

• CaudexCatena, a Caudena public blockchain analytics product for wallet exploration, labels, flows, dashboards, public-chain context, and related features.

2. Information We Collect

Account, Waitlist, and Contact Information

We may collect your name, email address, role or focus, organization name, country or region, login credentials, account settings, communication preferences, waitlist responses, and messages you send to us.

Billing and Subscription Information

For CaudexCatena MCP and any paid services, we may collect selected plan, billing cycle, subscription status, renewal date, billing name and address, tax information where required, invoices, receipts, payment status, failed-payment events, usage balance, top-up history, and payment-method metadata such as card brand, last four digits, and expiry date as provided by our payment processor.

We do not store full payment card numbers, card security codes, or raw payment credentials.

Product Usage and Technical Information

We may collect information about how you use the Services, including pages viewed, features used, search or prompt activity, account actions, authorization events, successful and failed CaudexCatena MCP calls, timestamps, request IDs, browser or client metadata, device information, IP address, approximate location, logs, diagnostic events, and security events.

Blockchain Queries, Prompts, and User-Submitted Context

Depending on how you use the Services, we may process blockchain addresses, transaction hashes, cluster identifiers, chain names, asset names, timestamps, exposure questions, labels, notes, comments, reports, investigation prompts, and other context that you or your AI client submit.

Some blockchain identifiers and public-chain activity may become personal data when they are linked or reasonably linkable to an identifiable person. You are responsible for ensuring that you are authorized to submit any information you provide to the Services.

Do not submit seed phrases, private keys, passwords, private case details, sensitive personal information, or information you are not authorized to provide.

Public Blockchain, Label, and Open-Source Context

The Services may display or use public blockchain records, public labels, entity categories, exposure information, cross-chain swap context, open-source information, and user-submitted or reviewed label context. Public blockchain data can be permanent and may be copied by third parties outside our control.

AI Client and Integration Information

For CaudexCatena MCP, we may process information needed to authorize, secure, meter, and troubleshoot requests from supported AI clients. Your AI client may receive CaudexCatena MCP responses and may summarize, store, or otherwise process them under that AI client’s own settings and policies.

Support and Communications

If you contact us, we may collect your contact details, message content, account information, support history, screenshots or attachments you provide, and related diagnostic information.

Cookies and Similar Technologies

We use cookies and similar technologies to operate the Services, keep accounts secure, remember preferences, support checkout and billing, understand website and product usage, diagnose errors, and measure performance. See our Cookie Policy for more detail.

7. Third-Party AI Clients

CaudexCatena MCP is designed to work with AI clients and MCP-capable tools that you choose. Caudena does not control how your AI client collects, uses, stores, trains on, or shares your prompts, files, logs, or outputs.

Review the terms, privacy policy, settings, and enterprise controls of your chosen AI client before using it with sensitive, regulated, confidential, or third-party personal data.

Caudena, users, service providers, and infrastructure may be located in different countries. Your information may be transferred to, stored in, or processed in countries other than where you live or work, including Cyprus, the European Economic Area, the United States, and other jurisdictions.

9. Data Retention

We keep personal information for as long as reasonably necessary for the purposes described in this Privacy Policy, including to provide the Services, manage accounts and billing, maintain security, resolve disputes, comply with legal obligations, and enforce agreements.

Retention periods may depend on account status, billing history, tax and accounting requirements, support history, legal or dispute needs, security needs, enterprise contract requirements, and whether information can be deleted, aggregated, or de-identified.

Payment, invoice, receipt, tax, and accounting records may be retained for legally required periods. Security and diagnostic logs are generally retained for limited periods unless needed for security, dispute resolution, legal compliance, or service integrity.

10. Security

We use administrative, technical, and organizational safeguards designed to protect personal information. These may include access controls, authentication, logging, encryption where appropriate, monitoring, provider review, and incident-response procedures.

No online service can guarantee perfect security. You are responsible for keeping your credentials secure and configuring your AI client, browser, wallet, and organization systems appropriately.
