JugaadTools is made by one person, and every message is read. Write in for any of these:

A wrong answer. If a calculator gives an incorrect result, please include the inputs you used so it can be reproduced and fixed.
A tool request. The best tools on this site exist because someone asked for them.
Anything else — questions, feedback, or a bug in how a page looks or behaves.

Replies usually take a day or two. Remember that the tools themselves never send your data anywhere — so if you are reporting a problem, the inputs you mention in your email are the only copy that exists.
