UseKitl is an independently run project, not a company. The way to reach the person maintaining it is through the project’s public repository on GitHub.
Report a bug or an error in a tool
Every tool page has a “Report a correction” link at the bottom that opens a pre-filled GitHub issue for that specific tool. You can also open a new issue directly. Include what you expected, what happened instead, and — for a calculation — the inputs you used, so it can be reproduced.
Suggest a tool or a feature
Open an issue describing what you’re trying to do and why the existing tools don’t cover it. Feature requests are read, but there is no guarantee of when — or whether — a given request gets built.
Source code
The full source for this site, including every tool’s calculation logic, is public at github.com/ZAID-EHT/UseKitl. If you can see exactly how a number was produced, you don’t have to take our word for it.
