Get in touch
Questions, bug reports, suggestions, or something that is just wrong — I want to know.
The best way to reach me is email. I check it regularly and respond to most messages, especially ones about specific tools that are broken or missing something.

What to include
If you're reporting a bug, the most helpful things to include are: the tool name, what you entered, what you expected to see, and what you actually got. A screenshot helps if the issue is visual.
If you're suggesting a new calculator or tool, just describe what it should do and what you'd use it for. Most of the tools on this site started as something I needed myself. The ones that get built next are usually the ones people ask for most.
What I'm not able to help with
I can't provide financial, legal, or medical advice. The tools on this site are calculators, not professional guidance. If a result looks off for your specific situation, run it by someone qualified in that area.
I also can't guarantee any particular response time. This is a side project alongside a full-time job. I try to respond within a few days.
