Terms of Service

Last updated: January 2026

By using Calcona ("the Site"), you agree to these terms. If you don't agree, please don't use the Site.

Use of the Site

The calculators and articles are provided free of charge for personal, non-commercial use. You may use them as often as you like, but you may not scrape, resell or redistribute the Site's content or tools without written permission.

No warranty

The Site is provided "as is" and "as available". We work hard to keep formulas accurate, but we make no guarantees that results are error-free, complete or suitable for your situation.

Not professional advice

Calculator results and articles are educational only. They are not financial, investment, legal, medical or construction advice. Always consult a qualified professional before making decisions based on the numbers — especially for loans, health, taxes or building work.

Acceptable use

• You may not use the Site for unlawful purposes.
• You may not attempt to disrupt, overload or reverse-engineer the Site.
• You may not reproduce copyrighted content without permission.

Limitation of liability

To the maximum extent permitted by law, Calcona is not liable for any indirect or consequential damages arising from use of the Site, including reliance on calculator results.

Changes

We may update these terms at any time. Continued use after changes means you accept the updated terms.
