ChatGPT Region Cloak

Align ChatGPT browser language and time zone signals with regional presets and an optional clean sign-in reset.

ChatGPT Region Cloak keeps browser-side language and time zone signals consistent on ChatGPT and OpenAI pages. Features: - Choose from 14 country or region presets and 22 IANA time zones. - Select a browser language independently, with 20 locale variants. - Align Accept-Language, navigator.language, default Intl formatting, and local Date behavior. - Remove the legacy `/zh-Hans-CN/` route from matching ChatGPT and OpenAI navigations. - Use a confirmed site-data reset for clean sign-in troubleshooting. Privacy: - Does not read chats, prompts, responses, page text, cookies, or account details. - Does not collect or transmit user data. - Contains no analytics, advertising, tracking, telemetry, or remote code. - Stores only extension preferences locally in the browser. This extension changes browser-side locale signals only. It does not change an IP address, account country, billing region, subscription, model access, or server-side experiment assignment. It cannot guarantee model quality or prevent server-side routing changes. ChatGPT and OpenAI are trademarks of OpenAI.
