Privacy

CartMargin is designed so that your business numbers never leave your device.

What happens to your inputs

Every calculation runs in your browser, in JavaScript. Prices, costs, fees, and any other number you type into the calculator are never sent to a server — there is no server to send them to. If you close the tab, the numbers are gone unless you chose to save them locally in your own browser.

Advertising on this site

CartMargin uses Google AdSense to support the site. AdSense may set cookies and use your visit data (such as your IP address and browsing activity) to show ads, including personalized ads based on your interests. This is separate from the calculator itself — your prices, costs, and other business inputs are never part of this and are never sent anywhere.

You can control the personalized ads Google shows you atGoogle Ad Settings, and learn more about how Google uses data from sites that use its services atHow Google uses information from sites that use our services.

No other analytics

Outside of AdSense, CartMargin does not run any analytics scripts and does not set its own cookies. If that changes, this page will be updated first.
