Acceptance of terms
By using SwiftSums, you agree to these terms. If you don't agree, please don't use the site.
Results are estimates, not advice
Every calculator on this site is provided for general informational purposes only. Financial calculators (mortgage, paycheck, compound interest, and similar) are not financial advice. Health calculators (BMI, calorie, pregnancy due date, and similar) are not medical advice and should not replace guidance from a qualified professional. Construction and science calculators are estimates and should be verified before use in any project where accuracy is safety-critical. Always confirm important figures with a qualified professional before relying on them.
No warranty
SwiftSums is provided "as is" without warranties of any kind, express or implied. I work to keep every formula correct, but I can't guarantee the site will be error-free, uninterrupted, or fit for any particular purpose.
Limitation of liability
To the fullest extent permitted by law, SwiftSums and its operators aren't liable for any loss or damage arising from your use of, or reliance on, this site or its calculators.
Acceptable use
Don't attempt to disrupt the site, scrape it at a rate that degrades service for other visitors, or use it for any unlawful purpose.
Changes to these terms
I may update these terms as the site changes. Continued use after a change means you accept the updated terms.
