Calculator data

Measurements and prices entered into the calculators are used only by the JavaScript running on your device. Project Matter does not submit, save, or transmit those values.

Storage and cookies

Your analytics choice is saved in local storage. If you allow analytics, Google Analytics may use first-party cookies to distinguish visits. Calculator values are not placed in cookies or local storage, and reloading a calculator restores its default examples.

Optional analytics

Google Analytics loads only after you select “Allow analytics.” It records page views, general device and location information, scrolls, outbound links, and calculator actions such as changing units or copying a result. It does not receive the dimensions, quantities, or prices you enter.

Advertising

Project Matter uses Google AdSense to display and measure ads. Google and its partners may process standard request information and, where allowed by your consent choices, use cookies or local storage for ad delivery, fraud prevention, measurement, and personalization.

Visitors in regions that require consent may see a Google-certified consent message before personalized advertising is enabled. You can review Google's advertising technologies policy for more information.

Third-party requests

The visual design loads fonts from Google Fonts, which receives standard web-request information such as your IP address and browser headers. Google Analytics receives data only with your permission. Google AdSense may receive standard request data when its script loads. Source links open external websites with their own privacy policies.
