MARKER GLOBAL PRIVACY POLICY
Last updated May 15, 2026
Marker Advisors, LLC ("Marker Advisors," "we," "us," or "our") is a cybersecurity channel research firm operating the Marker Global research platform at notes.markerglobal.com, including the Marker Global MCP connector, which provides authenticated access to our published research notes through Model Context Protocol-compatible AI assistants such as Claude and ChatGPT.
This Privacy Policy explains what information we collect, how we use it, who we share it with, and how long we keep it. It applies to all users who authenticate with the Marker Global MCP connector.
1. Who we are
Marker Advisors, LLC is a cybersecurity channel research firm registered in the State of Arizona, United States. Our research is distributed exclusively to active subscribers under individual subscription agreements.
For any questions about this Privacy Policy or your data, contact us at privacy@markeradvisors.com.
2. Information we collect
When you authenticate with the Marker Global MCP connector, we collect:
Account identity information — Provided through Auth0 during the OAuth authentication flow. This includes your email address and a unique user identifier issued by Auth0. We use this to associate connector activity with your active Marker Advisors subscription.
API key metadata (where applicable) — For subscribers who access the MCP via API key rather than OAuth, we store a SHA-256 hash of your API key, the date it was created, the date it was last used, and a revocation status. We do not store plaintext API keys.
Connector activity — Each call to the MCP server is logged at the infrastructure layer by our hosting providers (described below). This includes the request timestamp, request path, IP address, and user agent. We do not log the content of your queries, the research notes you retrieve, or any AI assistant conversations.
We do not collect financial information, browsing history outside the connector, location data, biometric data, or any special-category personal information through the MCP connector.
3. How we use your information
We use the information we collect to:
-
Authenticate your access to the Marker Global MCP connector and verify your subscription is active
-
Operate, maintain, and secure the service
-
Investigate and respond to security incidents, abuse, or unauthorized access
-
Comply with our legal obligations
We do not use your information for advertising, marketing profiling, AI model training, or sale to third parties.
4. Third-party service providers
We rely on a small number of third-party service providers to operate the Marker Global MCP connector. Each is contractually bound to handle data on our behalf:
Auth0 (Okta, Inc.) — Identity and authentication. Auth0 processes your email and authentication metadata. See Okta’s privacy policy at okta.com/privacy.
Supabase, Inc. — Database hosting for subscriber records, API key hashes, and research notes. See Supabase’s privacy policy at supabase.com/privacy.
Cloudflare, Inc. — Edge hosting for the Marker Global MCP endpoint, including default request-level logs as described in Section 2. See Cloudflare’s privacy policy at cloudflare.com/privacypolicy.
We do not share your information with any other third parties except as required by law.
5. Data retention
-
Account identity information is retained for as long as your subscription is active, plus up to 12 months after termination to support reactivation, billing reconciliation, and recordkeeping.
-
API key metadata is retained until the key is revoked, plus up to 12 months thereafter for audit purposes.
-
Connector activity logs held by our hosting providers are retained according to those providers' default retention policies, typically not exceeding 30 days.
6. Security
We protect your information with industry-standard safeguards, including TLS encryption in transit, encryption at rest in Supabase, OAuth 2.0 with RS256-signed JWTs validated against Auth0’s JWKS, and SHA-256 hashing of API keys. The MCP server runs read-only and cannot modify subscriber data or research content.
7. Your rights
Depending on your jurisdiction, you may have the right to access, correct, delete, or export your personal information, and to object to or restrict certain uses. To exercise any of these rights, contact us at privacy@markeradvisors.com. We will respond within 30 days.
If you are a California resident, you have additional rights under the California Consumer Privacy Act (CCPA), including the right to know what personal information we collect about you and the right to request deletion. We do not sell personal information.
If you are in the European Economic Area or the United Kingdom, you have rights under the General Data Protection Regulation (GDPR), including the rights listed above and the right to lodge a complaint with your local data protection authority. Marker Advisors processes your data on the legal basis of contractual necessity to provide the subscription service you have agreed to.
8. Children’s privacy
The Marker Global MCP connector is intended for institutional investment professionals and is not directed at children under 18. We do not knowingly collect information from children.
9. Changes to this Privacy Policy
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top. Material changes will be communicated to active subscribers by email.
