Contact

For anything at all — a wrong result, a calculator you would like to see, an advertising question, or a privacy request — write to info@alphacalcs.com. Every message is read and anything that needs a reply gets one.

Reporting a wrong result

Include the calculator name, the exact values you entered and the answer you expected. That is usually enough to reproduce the problem in a few minutes.

Suggesting a calculator

Tell us the question you were trying to answer, not just the tool name. The wording of the question often shows which inputs the calculator actually needs.

Advertising

Advertising enquiries are welcome at the same address. We do not publish paid links inside article text or dress advertising up as a recommendation.

Privacy requests

For access, correction, deletion or objection requests under the GDPR, write to info@alphacalcs.com and allow a little time for a reply. See the privacy policy for what is held, which is very little.
