Frequently asked questions

Is Calculixy really free?

Yes — all 20 calculators are permanently free with no sign-up, no subscription, and no data collection. The site is supported by non-intrusive advertising placed below the calculator interface.

Can I trust the calculator results?

Every formula is verified against authoritative published sources — IRS tables for salary, HUD limits for reverse mortgage, Mifflin-St Jeor for calorie estimates. Results are estimates for educational purposes, not professional financial, medical, or legal advice.

Do you store what I enter into the calculators?

No. All calculation logic runs entirely in your browser. Nothing you type — your salary, mortgage amount, weight, due date, or any other input — is ever transmitted to our servers. See our Privacy Policy for full details.

I found an error in a calculator. What should I do?

Please use the form above and select “Incorrect Calculation” or “Bug Report.” Include the calculator name, your inputs, and the result you received. We investigate all formula reports and typically publish corrections within 24 hours.

Can I request a calculator that doesn’t exist yet?

Yes. Select “Feature Request” from the dropdown and describe the calculation you need. We review all requests and prioritize those that address real, practical use cases not well served by existing tools.

How do I make a privacy or data deletion request?

Select “Privacy/Data Request” from the dropdown. Since we do not collect personally identifiable information through calculator inputs, most data requests relate to contact form submissions or analytics identifiers. We respond to all privacy requests within 30 days as required by applicable law.
