Every calculation runs entirely in your browser. We don't send your numbers anywhere. We don't store them. We don't track you. View the page source if you don't believe us.
If the calculators make you curious about the rest of the WTF family, the WTF Suite can decode your mystery charges, hidden fees, contracts, and more. But we'll never pressure you to sign up. The calculators are free forever.
