Privacy Policy — JWT Decoder

Last updated: 2026-08-07

Summary

JWT Decoder does not collect, store, transmit, or share any user data. There is no data collection of any kind.

What the extension does

You paste a JWT into the popup, or select one on any page and use the right-click "Decode as JWT" menu. The extension decodes the token's header and payload entirely inside the popup, using only your browser's built-in JavaScript — nothing leaves your machine.

Data collection

This extension does not collect any personal information, browsing history, analytics, or usage data. It has no background network activity and makes no requests to any server. The token you decode is never sent anywhere; it is only ever read locally to display its decoded contents to you.

Permissions

The extension requests contextMenus (to add the right-click "Decode as JWT" entry) and storage (used only to pass the selected token from the right-click menu to the popup on your own device). Neither is used to collect or transmit any data.

Third parties

This extension does not integrate with, or share data with, any third-party service, advertiser, or analytics provider.
