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. If you revoke an earlier permission, the page reloads to remove the already-loaded Google tag. Your choice is stored in your browser's local storage so the site can remember it.

Google AdSense

This site loads Google AdSense publisher code to support advertising. Google may receive ordinary request information when that code loads. We do not send the envelope dimensions, weight, or calculated postage to AdSense. Advertising storage, ad user data, and ad personalization remain denied unless an appropriate regional consent flow updates that choice.

You can reopen the analytics controls at any time.
