Calquly is run by Alexis Hidalgo-Gato. The fastest way to reach me is email:
Reporting a wrong result
This is the most useful thing you can send. Include which calculator you were using, the exact values you entered, the result you got and the result you expected. Every report gets checked against the test suite, and if there is a genuine bug the fix and a new test go in together.
Suggesting a calculator
Tell me what you were trying to work out and, if you can, what you ended up using instead. Suggestions that describe a real task get built first.
Privacy, data and legal
Use the same address for anything covered by the privacy policy or the terms of use, including data requests.
What I cannot help with
I cannot check your homework, do your taxes, review a contract, or advise on a construction project. The calculators do the arithmetic; the judgement is yours.
