📏 Telemetry

Chroma contains a telemetry feature that collects anonymous usage information.

Why?

We use this information to help us understand how Chroma is used, to help us prioritize work on new features and bug fixes, and to help us improve Chroma’s performance and stability.

Opting out

If you prefer to opt out of telemetry, you can do this in two ways.

In Client Code

Set anonymized_telemetry to false in your client's settings:

from chromadb.config import Settings
client = chromadb.Client(Settings(anonymized_telemetry=False))

In Chroma's Backend Using Environment Variables

Set ANONYMIZED_TELEMETRY to False in your shell or server environment.

If you are running Chroma on your local computer with docker-compose you can set this value in an .env file placed in the same directory as the docker-compose.yml file:

ANONYMIZED_TELEMETRY=False

What do you track?

We will only track usage details that help us make product decisions, specifically:

• Chroma version and environment
• Usage of embedding functions that ship with Chroma and aggregated usage of custom embeddings (we collect no information about the custom embeddings themselves)
• Collection commands. We track the anonymized uuid of a collection as well as the number of items
  • add
  • update
  • query
  • get
  • delete

We do not collect personally-identifiable or sensitive information, such as: usernames, hostnames, file names, environment variables, or hostnames of systems being tested.
