What's Wrong?

Description

Claude Code makes continuous network calls to datadoghq.com every few seconds during the entire session, which is completely undisclosed in the official documentation.

## Environment

• Claude Code Version: 2.0.76
• Platform: WSL2 (Linux 6.6.87.2-microsoft-standard-WSL2)
• Network Setup: Running through corporate proxy

## Observed Behavior

Proxy logs show:

1. datadoghq.com - Continuous calls every few seconds throughout the entire Claude Code session
2. GitHub API - Called on startup
3. Both services not mentioned in official documentation

### Example Pattern
[timestamp] datadoghq.com - request
[timestamp+3s] datadoghq.com - request
[timestamp+6s] datadoghq.com - request
[timestamp+9s] datadoghq.com - request
... (continues throughout session)

## Expected Behavior

According to the official documentation, Claude Code only uses:

• Statsig: for telemetry
• Sentry: for error logging

There is no mention of Datadog anywhere in the documentation.

## Critical Privacy Concerns

1. Undisclosed continuous monitoring: Persistent background network calls every few seconds
2. Unknown data transmission: What is being sent so frequently?
3. Potential data leakage: What information is being transmitted in real-time?
4. Corporate compliance violation: Continuous external calls to undisclosed services

## Questions

1. Why is Claude Code connecting to datadoghq.com every few seconds?
2. What data is being transmitted so frequently?
3. Why is this completely absent from the documentation?
4. Is this monitoring user activity in real-time?
5. Is Datadog collecting metrics on user code, commands, or behavior?
6. How can users disable this completely?

## Reproduction Steps

1. Set up a network proxy/monitor (e.g., corporate proxy, mitmproxy, Wireshark)
2. Start Claude Code in any directory
3. Observe continuous network calls to datadoghq.com every few seconds
4. Calls continue throughout the entire session

## This is a Serious Issue For:

• Enterprise users: Violates corporate data governance policies
• Regulated industries: HIPAA, SOX, PCI-DSS compliance violations
• Privacy-conscious users: Continuous unreported data transmission
• Network security: Unexplained persistent connections trigger security alerts
• Bandwidth-limited environments: Unnecessary continuous network usage
• Air-gapped or restricted networks: Tool completely unusable

## Required Actions

1. Immediately disclose what data is being sent to Datadog and why
2. Document all third-party services in the official documentation
3. Provide configuration option to completely disable these calls
4. Add hard kill switch for all network calls except Claude API
5. Provide offline mode for users who cannot have continuous external connections

## Legal and Trust Implications

• GDPR: Users in EU must be informed and consent to continuous data collection
• CCPA: California users have right to know what data is collected
• Enterprise contracts: May violate data processing agreements
• User trust: Undisclosed persistent monitoring seriously damages trust

This needs urgent clarification and fix. Users have a right to know what data is leaving their machines continuously.

What Should Happen?

1. Immediately disclose what data is being sent to Datadog and why
2. Document all third-party services in the official documentation
3. Provide configuration option to completely disable these calls
4. Add hard kill switch for all network calls except Claude API
5. Provide offline mode for users who cannot have continuous external connections
