SECURITY AND PRIVACY

NoobHeaders respects your privacy:

• No external connections: no servers, no telemetry
• Open source: audit the code yourself on GitHub

PERMISSIONS EXPLAINED

storage: Save your profiles locally
declarativeNetRequest: Modify HTTP headers (core functionality)
declarativeNetRequestFeedback: Verify that rules are active

No permission is superfluous. Each one is essential for proper operation.
