This privacy policy explains how JWT Decoder handles information when you use our website. We are committed to protecting your privacy and being transparent about our practices.
JWT Decoder does not collect, store, or transmit any personal information or JWT tokens. All JWT decoding, validation, and analysis operations are performed entirely within your web browser using JavaScript. The JWT tokens you input and the decoded results you receive never leave your device.
Your JWT tokens are never uploaded to our servers, stored in databases, or transmitted over the network. All processing happens locally in your browser. When you paste a JWT token into our decoder, it remains on your device and is processed using client-side JavaScript. This ensures complete privacy and security for sensitive authentication tokens, API tokens, and any other JWT data you work with.
