Contact us

The fastest way to reach KakouCalc is email: contact@serverkakoulabs.org

Messages go directly to the site's operator and are read personally. There is no contact form by design — the site collects no data, and email keeps it that way. If you write to us, we receive your address and message and use them only to reply (see the Privacy Policy).

What to write about

Report an error

Think a calculator gave a wrong figure? Send the calculator's name, the exact inputs you used, the result you got, and the result you expected. Accuracy reports get first priority — every report is checked against our verification suite and fixed if confirmed.

Suggest a calculator

Missing a tool you need? Describe what it should compute and, if you can, the inputs you'd expect it to ask for.

Embedding & partnerships

The embed widget is free to use straight from any calculator page. Write in for anything beyond that — custom sizing, multiple widgets, or press.

Privacy & policy

Questions about the Privacy Policy or Terms of Service, or about an ad shown on the site.

One thing we can't help with

We cannot give personal financial advice — not by email, and not through the calculators. The tools are educational; for decisions about your own money, please consult a qualified professional. See about us for how the site is run.
