Purpose
Header Relay is a Chrome extension for API development and testing. It helps developers inspect browser-based HTTP requests when fixed or captured headers are attached.
Host permissions
The extension requests access to all URLs so developers can choose local, staging, internal, or test origins. Header capture and attachment are limited by the enabled profile's Target Origins and Excluded Paths.
Data stored locally
Profiles, captured header values, session state, and audit logs are stored locally in the extension's browser storage and IndexedDB. Captured values are shown in plain text in the popup and management screen so developers can verify the actual values used on requests.
Limited use
Browser permissions and locally stored data are used only for the extension's single purpose: capturing configured response header values and relaying configured request headers for developer-selected target origins. The data is not used for advertising, creditworthiness, lending, or unrelated purposes.
Data sharing
The extension does not transmit profile settings, captured headers, audit logs, or browsing data to external servers. Network requests are only the pages and APIs you open while using configured profiles.
No human access
The developer does not receive, inspect, sell, or share profile settings, captured values, audit logs, or browsing activity. This data remains in the local Chrome profile unless you choose to export or disclose it.
Audit log retention
Audit logs are capped at the 1,000 most recent entries, and entries older than 7 days are removed automatically. Logged URLs include only the origin and pathname; query strings and fragments are omitted. All audit logs can be removed from the management screen.
Your control
You can disable a profile, remove target origins, clear captured values, or uninstall the extension to stop capture and attachment behavior.
