Questions, corrections, and calculator suggestions all land in the same inbox, and all of them are read.
Write to thesaadster.dev@gmail.com and you'll hear back, usually within a few days.
Reporting a wrong result
If a calculator gives an answer you believe is wrong, include three things: the tool's URL, the exact inputs you entered, and the result you expected. With those, most fixes ship within a day or two. Every tool page shows the formula it uses, so it's also worth a quick check that the difference isn't a different convention (for example, percent change measured against the starting value rather than the ending one).
Suggesting a calculator
A one-line description of the question you want answered is enough — "how much protein per day at my weight" beats "a nutrition calculator." Suggestions that solve a concrete problem are the ones that get built first.
