Free to use
CalcPark tools are free for personal and commercial use. You may link to any page. You may not copy the site or its tools and present them as your own, or use automated means to scrape the site at a rate that affects other visitors.
Results are estimates
Every tool shows the method it uses, but results depend on your inputs and on the formula's assumptions. Health, pregnancy, alcohol, finance and date calculations are for information only and are not medical, legal, tax or financial advice. Check important decisions with a qualified professional.
No warranty
The tools are provided "as is" without warranty of any kind. To the extent permitted by law, CalcPark is not liable for losses arising from the use of, or inability to use, the site or its results.
Your files
File tools process your files in your browser. You are responsible for the content you process and for keeping copies of your originals.
Changes
These terms may change when the site changes; the current version is always on this page.
