🙋 Quick answers

Can I request a new calculator?

Absolutely — pick "Suggestion" above and describe what you need. It's one of the best reasons to write in!

I found a wrong result. What do I do?

Please report it! Pick "Bug Report" and include the calculator name and the result you expected. I'll fix it ASAP.

Is CalcDen really free?

Yes, 100%. The site is kept free through ads via Google AdSense — no subscriptions, no hidden charges, ever.

Are my calculator inputs stored?

Nope. All calculations run directly in your browser. Nothing you type is ever sent to a server.
