Calculator inputs
Calculator inputs are processed in your browser. ProsperMath does not transmit the financial figures you enter to Google Analytics or store them on a ProsperMath server.
Browser storage
The site uses local browser storage to remember your preferred display currency. This preference remains on your device and can be removed by clearing site data in your browser.
Analytics
ProsperMath uses Google Analytics to understand page visits and general interactions such as which calculator or guide is opened, whether a calculation is completed, which currency or category is selected, whether a share link is copied and whether a guide-to-calculator link is used. Calculator amounts and other figures entered into fields are not included in these analytics events. Google may process device, browser and approximate location information under its own policies.
Advertising and consent
ProsperMath includes Google AdSense technology for site verification and future advertising. Advertising and analytics availability, storage and personalisation can depend on location, consent choices and browser settings.
