Header Forge does not collect, store, transmit, or share any user data.
All header rules created by the user are stored locally on the user's device using the browser's extension storage (browser.storage.local). This data never leaves the device and is not accessible to the developer or any third party.
The extension does not use analytics, telemetry, or tracking of any kind. It makes no network requests of its own. The host permission is used exclusively to apply the user's header rules to web requests via the declarativeNetRequest API; no page content or browsing activity is read or recorded.
Uninstalling the extension removes all stored data.
