Local by design.
Clear by policy.

Last updated: July 26, 2026

01

Purpose

RequestHeaders adds HTTP request headers only according to key-value rows explicitly created and enabled by the user. It is intended for web development, API testing, and debugging.

02

Data handled

RequestHeaders stores profile names, header names, header values, row enabled states, the selected profile, and the global enabled state in Chrome’s local extension storage.

Header values may contain authentication information or other sensitive data if a user chooses to enter it. Users should only add values they intend to send to websites while the rule is enabled.

03

How data is used

Enabled values are applied locally through Chrome’s declarativeNetRequest API. While the global switch is on, those headers may be added to HTTP and HTTPS requests handled by Chrome’s network stack.

04

Collection, transmission, and sharing

RequestHeaders does not transmit extension settings, browsing activity, or usage information to the developer or any third party. It contains no analytics, advertising, tracking, account system, remote code, or external synchronization service.

RequestHeaders does not sell or share user data and does not use data for advertising, creditworthiness, or purposes unrelated to its single purpose.

05

Retention and deletion

Settings remain in local browser extension storage until the user removes rows or profiles, clears the extension’s storage, or uninstalls RequestHeaders.

Uninstalling the extension removes its locally stored configuration through Chrome’s extension-data controls.
06

Permissions

storage

Retains user-created profiles and header settings locally between browser sessions.

declarativeNetRequest

Applies only the request-header rules explicitly configured and enabled by the user.

Host access

Required because enabled headers can apply to HTTP and HTTPS websites. Individual rows and all rules can be disabled.

07

Changes and contact

Material changes to this policy should be reflected in the Chrome Web Store listing before the corresponding extension update is published.

For privacy or support questions, use the publisher contact displayed on the RequestHeaders Chrome Web Store listing.
