Overview
JWT Debugger is designed as a client-side tool for decoding, verifying, and generating JSON Web Tokens,
plus encoding and decoding Base64 text.
Token processing is intended to happen in your browser, not on an application server operated by this tool.
Information You Enter
Tokens, secrets, public keys, private keys, and JSON payloads entered into the tool are processed locally in
your browser. The static app does not intentionally transmit this input to a backend service for decoding,
validation, signing, verification, or Base64 conversion.
Information We Do Not Intentionally Collect
This tool does not intentionally collect account information, authentication tokens, secrets, private keys, or
decoded JWT payloads. Do not paste production secrets or sensitive personal data unless you understand and
accept the risks of using a browser-based utility.
Local Storage and Browser Features
The site may store simple preferences, such as the selected light or dark theme, in your browser local storage.
Clipboard actions only run when you click copy-related controls and depend on your browser permissions.
Analytics, Hosting, and Third Parties
We use Google Analytics (GA4) to measure aggregate site traffic and page usage. No JWTs, secrets, private keys,
or decoded payloads entered into the workspace are ever transmitted to Google Analytics or any server.
If this site is hosted by a third-party provider, that provider may collect standard technical logs such as IP
address, user agent, requested URL, timestamps, and error information. External links, including LinkedIn and
RFC references, are governed by their own privacy policies.
Work in Progress and Accuracy
JWT Debugger is a work in progress. Outputs may be incomplete, invalid, inaccurate, or unsupported in some
cases, including unusual algorithms, malformed tokens, browser API differences, invalid keys, or edge cases in
JWT/JWS handling. Always independently verify results before relying on them in production, security, legal, or
compliance decisions.
No Warranty
The tool is provided as-is and as-available, without warranties of any kind. You are responsible for how you
use the tool, the data you enter, and any decisions you make based on its output.
Security
Client-side processing can reduce server-side exposure, but it does not eliminate browser, device, extension,
clipboard, network, or hosting risks. Use test tokens where possible and avoid entering highly sensitive
production secrets.
Children's Privacy
This tool is intended for developers and technical users. It is not directed to children and does not knowingly
collect personal information from children.
Changes
This policy may be updated as the tool evolves. Continued use after an update means you accept the revised
policy.
