Terms of Service

Using SparkJSON

SparkJSON provides a set of free, browser-based developer utilities (JSON formatting, JWT decoding, Base64 encoding, regex testing, and others listed on the tools page). By using this site, you agree to these terms. If you don't agree with them, please don't use the site.

No warranty

These tools are provided "as is," without warranty of any kind, express or implied. We make a genuine effort to handle edge cases correctly (malformed input, huge files, deeply nested data, and so on), but we cannot guarantee that every tool produces a correct or complete result for every possible input. Don't use output from these tools as the sole basis for a decision where correctness is safety- or business-critical without independently verifying it.

Your responsibility for generated output

Tools like the password generator and UUID generator produce output based on your chosen settings (length, character sets, and so on). You are responsible for choosing settings appropriate to your use case and for how you store and use the result — for example, we strongly recommend using a reputable password manager to store generated passwords rather than reusing or writing them down insecurely. We have no way to know how generated output is subsequently used, since nothing you generate is transmitted to us.

The JWT decoder specifically does not verify signatures

As stated on the tool itself: decoding a JWT with this tool only reveals its header and payload claims. It does not check the token's signature, and a successfully decoded token is not evidence that the token is authentic, unexpired-in-a-security-relevant-sense, or safe to trust. Signature verification must be performed server-side with the actual signing key.

Acceptable use

Please don't use SparkJSON to process content that is illegal to possess or distribute, or in a way that attempts to abuse, overload, or gain unauthorized access to the hosting infrastructure serving this site.

Availability

We aim to keep SparkJSON available and free, but we don't guarantee uninterrupted uptime. The site may occasionally be unavailable for maintenance, hosting issues, or reasons outside our control.

Intellectual property

The SparkJSON name, design, and original code are owned by their respective creators. You're welcome to use the tools for any personal or commercial purpose; you may not copy the site's design or codebase wholesale and represent it as your own.

Limitation of liability

To the fullest extent permitted by law, SparkJSON and its maintainers are not liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, these tools, including but not limited to data loss or business interruption.

Changes to these terms

We may update these terms occasionally to reflect new tools or clarify existing language. Continued use of the site after a change constitutes acceptance of the updated terms.
