Privacy & analytics

The calculator works without an account and does not send the numeric envelope dimensions or weight you enter to our analytics service.

Optional Google Analytics

If you select “Allow analytics,” this site loads Google Analytics 4 using measurement ID G-HNEYDX8JLL. It records page visits and a limited event when the calculator is used, including the envelope preset, mail category, optional-service choices, and whether a valid price was returned. It does not receive the numeric measurements or weight you entered.

If you select “Essential only,” the Google Analytics script is not loaded and no analytics data is sent from this site. Your choice is stored in your browser's local storage so the site can remember it.

You can reopen the analytics controls at any time.
