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.
Report outdated information
Guides and tools that depend on external data — rates, pricing, statutory figures — show when they were last verified. If a figure looks stale or a guide references something that has since changed, open an issue with a link to the page and, where possible, a source for the current figure. See Methodology for how data freshness is tracked.
Suggest a tool or a feature, or send general feedback
Open an issue describing what you’re trying to do and why the existing tools don’t cover it, or anything else you think should change. Feature requests and general feedback 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.
