Subprocessors

Last updated: June 28, 2026

Not A Number Labs Incorporated ("Chorus," "we," "us," "our") works with a small number of trusted third parties, called sub-processors, that help us operate the Service. A sub-processor is a company we use to process customer data on our behalf, for example to host our systems, store data, or generate the agent's responses. This page lists the sub-processors we currently use and what each one does.

1. Current sub-processors

The companies below process customer data on our behalf to deliver the Service. All of them operate in the United States.

• Anthropic: Provides the large language models that power the agent. It processes the message content we send to the model in order to generate a response. Anthropic does not train its models on this data.
• Amazon Web Services: Cloud hosting and infrastructure for our application and database.
• Neon: Managed PostgreSQL database where customer data is stored.
• Render: Hosts the service that routes messages between platforms such as Slack and the agent.
• Clerk: Authentication and user account management.
• Nango: Manages the OAuth connections between an agent and the third-party tools a customer chooses to connect.

2. How we choose sub-processors

Before a sub-processor handles customer data, we review how it stores and protects that data and confirm it offers terms consistent with the commitments in our privacy policy. We give each sub-processor only the data it needs to perform its function.

3. Changes to this list

We keep this page up to date when we add or remove a sub-processor that handles customer data. We encourage you to check back here for the current list.
