JWT Viewer & Decoder by Lotarion is a browser extension that helps users detect, inspect, and copy token-related values available in the current browser context.
The extension may access cookies, local storage, session storage, and token-like values available on the active website tab in order to identify and display JWT or related token data to the user.
The accessed data is used only to provide the core functionality of the extension, including displaying token information inside the extension popup, decoding JWT payloads locally in the browser, and allowing users to copy token values manually.
JWT Viewer & Decoder does not collect, store, sell, transmit, or share user data with the developer or with any third party. All processing happens locally in the user's browser.
The extension does not retain token data after use and does not maintain any external database, analytics pipeline, or remote logging system for such information.
JWT Viewer & Decoder does not use external analytics services, advertising services, or remote servers to process token or browsing data.
Because token data may be sensitive, users should handle copied token values carefully. Token values copied using the extension may be temporarily available in the system clipboard until replaced.
This Privacy Policy may be updated from time to time. Any updates will be posted on this page with a revised “Last updated” date.
