Privacy policy: JWT Decoder

What this tool does with your token
- The token and any key you paste are handled by code running in your browser on your own device, including the signature check, which uses the browser's built-in cryptography. Nothing is sent to us or to anyone else, and nothing is stored.
- There is no account and no cookie. We count visits with a code that changes every day and cannot identify you, plus the site that linked you here and your device type, and how many tokens are decoded: only the algorithm name, never a token, a claim or a key.
This page covers JWT Decoder only. The site-wide Privacy Policy covers everything else, and the Terms of Use apply to every tool.
