Your tool inputs stay in your browser

Calculations run locally. We do not send calculator inputs to Google Analytics or store calculation history on a server. The site does not require an account.

Where analytics runs

Analytics covers our English and Chinese homepages, calculator directory, roof pitch, compound interest (English and Chinese), raised bed soil, mulch, and privacy pages. Both versions of the Wi-Fi sign maker contain no analytics or tracking scripts. Wi-Fi usage is therefore not included in Google Analytics reports; missing data does not mean zero usage.

We compare visits using each page path. These figures measure page traffic, not completed calculations, downloads or successful Wi-Fi connections.

Google Analytics

Google Analytics 4 loads by default unless you have turned it off in Analytics settings. We use it to understand page visits, traffic sources and basic engagement. Google may process device and browser information, approximate location derived from your IP address, and cookie identifiers. Google receives network connection information when your browser contacts its servers.

If a saved choice turns analytics off, our analytics code does not load Google's tag or send analytics requests. We disable advertising personalization and Google signals. We do not enable automatic form, site search, download or outbound-link measurement. Our page-location parameter excludes query strings and fragments, and our referrer parameter contains only the referring origin.

Google Analytics uses first-party cookies such as _ga and _ga_* to distinguish visits. These can last up to two years, depending on browser and Google settings. See Google's privacy policy for its data practices and international processing.

Your choices

Turning analytics on or off does not change access to our tools. Use Analytics settings in the footer to change your choice. We remember your choice in browser storage for up to 180 days. After the choice expires, or browser storage is cleared, analytics is enabled by default again. Turning analytics off stops future analytics and attempts to remove this site's Google Analytics cookies; it does not erase data previously collected by Google. You can also clear cookies and browser storage yourself. If storage is blocked, your choice may apply only to the current page.

Your appearance preference is stored separately in your browser to remember light, dark or system mode.
