Privacy policy

Calculator inputs stay in your browser
Every calculator on this site runs entirely on your device. The incomes, custody details and other figures you enter are never sent to our servers, stored, or shared. Reloading the page clears them. There are no accounts and no forms that collect personal information other than email you choose to send us.
Analytics
We may use privacy-respecting analytics to count page views and understand which calculators are used. Where analytics cookies are used, they do not contain calculator inputs.
Advertising
This site may display advertising served by third parties such as Google AdSense. These providers may use cookies or similar technologies to show ads based on your visits to this and other websites. You can opt out of personalized advertising through Google's Ads Settings at adssettings.google.com or through the Digital Advertising Alliance at optout.aboutads.info. Advertisers never receive the figures you enter in a calculator.
Theme preference
If you switch between light and dark mode, the choice is saved in your browser's local storage so the site remembers it. Nothing else is stored there.
If you email us, we keep the message to respond and to track corrections. We do not add you to any list or share your address.
