# Telemetry

> Understanding Browser Use's telemetry

## Overview

Browser Use is free under the MIT license. To help us continue improving the library, we collect usage telemetry with [PostHog](https://posthog.com). Telemetry may include usage metadata and task-level data such as task instructions, URLs visited, action traces, errors, and final results. We may use this information to operate, debug, secure, analyze, develop, and improve Browser Use and related offerings, including by creating aggregated, de-identified, or sanitized datasets and workflow patterns in accordance with our Terms of Service and Privacy Policy.

## Opting Out

You can disable telemetry by setting the environment variable:

```bash .env theme={null}
ANONYMIZED_TELEMETRY=false
```

Or in your Python code:

```python theme={null}
import os
os.environ["ANONYMIZED_TELEMETRY"] = "false"
```

<Note>
  Even when enabled, telemetry has zero impact on the library's performance. Code is available in [Telemetry
  Service](https://github.com/browser-use/browser-use/tree/main/browser_use/telemetry).
