Disclaimer

The tools and articles on this site are provided for general information and utility purposes. While we document the exact formulas and algorithms each tool uses — so you can verify any result — outputs are estimates that depend entirely on the inputs you provide.

No professional advice. Nothing here is medical, nutritional, psychological, financial, investment, tax, accounting, legal or employment advice. Health calculators (BMI, body fat, TDEE, pregnancy dating and similar) implement published population formulas and cannot account for individual clinical factors. Financial calculators (loans, ROI, payroll and similar) cannot know your actual contract terms, local rates or tax situation. Decisions that matter — health, money, law — deserve a qualified professional who can see your full picture.

External content. Articles reference third-party standards and studies for verification; we link to primary sources where possible and are not responsible for their content or availability.

Your data. Tools run in your browser; we do not see, store or transmit your inputs. That privacy is architectural — but it also means we cannot recover a computation you did not save.
