FAQ
Common Questions
Are all calculators really free?
Yes — every single calculator on CalcVerseHub is completely free. No subscription, no premium tier, no paywall. We are committed to keeping it that way.
Do you store the data I enter?
No. All calculations happen entirely inside your browser. Your inputs are never transmitted to or stored on any server. We have no database of user data whatsoever.
I found a calculation error. What should I do?
Please reach out via email with the calculator name, the values you entered, and the result you received vs. what you expected. We take accuracy very seriously and will investigate and fix it promptly.
Can I suggest a new calculator?
Absolutely! We love feature requests. Send us an email describing the calculator you need and the formula it should use. If it's widely useful, we'll build it.
Can I embed or link to a CalcVerseHub calculator?
Linking is always welcome. For embedding, please contact us — we're exploring embedding options for future releases.
Is CalcVerseHub open source?
We are working toward making the project publicly available. Stay tuned for announcements.
