Calculator values
Calculator inputs stay only on the current page and reset to defaults when you reload or return. If you copy a URL containing transferable calculator inputs, anyone receiving that URL may see those included values.
Google AdSense and advertising
KuajingSuan uses Google AdSense to provide advertising. When advertising is not active or no ad inventory is available, a page may show only a reserved advertising space. Google and its advertising partners may place or read cookies, use browser local storage or similar technologies, and use web beacons or IP addresses as a result of serving ads on this website.
Advertising data may be used to deliver and measure ads, limit how often an ad appears, detect fraud and abuse, and provide personalized or non-personalized advertising. Personalized ads may use information about your activity or interests; non-personalized ads may still use contextual information such as the page topic, general location, or time of day.

Cookies and local storage
We do not save calculator inputs in browser local storage. This website uses local storage to remember your analytics-consent choice. Google services may use cookies or similar browser storage for advertising, measurement, security, and preference controls.
You can open the Cookie Settings control shown on this website to accept or reject analytics. You can also use your browser settings to review, block, or delete cookies and site data, including local storage. Blocking browser storage may affect saved choices or some website and advertising functions.
Turn off personalized advertising
You can use Google My Ad Center to turn personalized ads on or off and manage information used for advertising. Turning off personalization does not necessarily remove advertisements; you may still see non-personalized or contextual ads.
Statistics and analytics tools
Google Analytics 4 loads only after you give analytics consent. We may record page and interaction names, calculator type, language, and device context. We do not send selling prices, costs, profit, product dimensions, or other business values as custom analytics event parameters.
