Privacy Policy for Header Override
Last updated: July 10, 2026

Header Override lets users create local rules that override HTTP request headers for URL patterns they choose.

Data the extension handles
Header Override stores the rules you create in your browser's local extension storage. These rules may include:

Header names.
Header values.
URL filter patterns.
Whether each rule is enabled.
The extension uses these rules only to configure the browser's declarativeNetRequest API and apply the header changes you requested.

Data collection and sharing
Header Override does not send your rules, browsing activity, website content, or any other personal data to the developer or to any third party. The extension does not use analytics, advertising, tracking, remote code, or external servers.

Data storage and deletion
Rules are stored locally in your browser using extension storage. You can edit or delete rules from the extension popup. Uninstalling the extension removes the locally stored extension data according to the browser's normal extension storage behavior.

Permissions
Header Override requests access to all URLs so that user-created header rules can apply to the websites and requests selected by the user's URL filters. It requests storage permission so rules can be saved locally.
