All calculations run in your browser. The sizes, weights and settings you enter are not sent to any server and are not stored.
Analytics: this site uses Cloudflare Web Analytics to count visits. It does not use cookies or local storage and does not build a profile of you; it records anonymous, aggregate visit data such as the page viewed, referrer, country, browser type and page load timing. The numbers and settings you type into the calculators are never included.
The site has no accounts, sets no cookies and shows no advertising. If this changes, this page will be updated first.
Links to carrier websites and to SellerMath open those sites, which have their own privacy policies. The SellerMath link carries only the billable weight, its unit and the carrier preset name in the URL.
The hosting provider may keep standard server logs (such as IP address and time of request) for security.
