Terms of use
By using JSON Hearth, you agree to use the tools lawfully and to verify important output before relying on it.
The service
JSON Hearth provides free browser-based utilities for developers. Features may be changed, added, removed or temporarily unavailable without notice.
Your responsibilities
You are responsible for the content you process, for having the right to use it and for checking generated schemas, code, conversions, repairs and comparisons before using them in production systems.
No security guarantee
A decoded JWT is not a verified JWT. Syntax validation does not establish that data is safe, authentic or suitable for a particular system. Do not treat tool output as a substitute for security review, testing or professional advice.
Acceptable use
Do not use the service to violate law, infringe rights, interfere with the website, attempt unauthorized access or distribute malicious content.
Disclaimer and liability
The service is provided “as is” and “as available,” without warranties of accuracy, availability or fitness for a particular purpose. To the fullest extent permitted by law, the operator is not liable for indirect, incidental or consequential loss arising from use of the service.
Changes
These terms may be updated as the service develops. Continued use after an update means you accept the revised terms.
