HEADER PROFILES

Privacy Policy

Header Profiles is a local browser tool for creating and switching HTTP header rules. Your rules stay in your browser.

Last updated: July 22, 2026

1. Scope

This policy applies to Header Profiles - HTTP Header Switcher (the “extension”). The extension lets you create profiles containing HTTP request or response header rules and URL matching conditions for development, testing, and debugging.

2. Information stored locally

The extension stores only the settings you intentionally create in the extension, including profile names, header names and values, rule operations, enablement states, URL matching conditions, your interface language preference, and rule application status. Application status includes local request identifiers, validation results, and the last apply outcome so the extension can distinguish saved settings from successfully applied rules. Depending on what you enter, header values may contain authentication information such as an API key or authorization token.

The extension does not automatically read or record your browsing history, web page content, form data, passwords, cookies, or request and response bodies.

3. How information is used

Your settings are used only to create the browser rules you enable. These rules can add, append, remove, or modify HTTP headers for the URLs you specify. They are not used for advertising, analytics, profiling, or any purpose unrelated to this functionality.

4. No external collection or sharing

The extension does not operate a server and does not transmit your profiles, header values, URL rules, browsing activity, or page content to the developer or any third party. It does not sell, rent, share, or use your data for advertising.

5. Storage and your controls

Settings are stored in your current Chrome profile using Chrome’s local extension storage. They remain there until you edit or delete them, clear the browser profile data, or uninstall the extension. You can also export a backup or import a backup using the controls in the extension.

Do not store passwords, long-lived access tokens, or other highly sensitive secrets in header rules. You are responsible for the values you add and the websites to which you apply them.

6. Permissions

7. Changes to this policy
