+## Telemetry
+
+As with the Haystack core package, we rely on anonymous usage statistics to determine the impact and usefulness of the experimental features. For more information on what we collect and how we use the data, as well as instructions to opt-out, please refer to our [documentation](https://docs.haystack.deepset.ai/docs/telemetry).
