What This Version Stores
The calculators run in your browser. Measurements you type are not sent to us, because this version has no account and no form that submits to a server. There is no ZIP lookup and no region file.
This version does not install an analytics beacon and does not set its own cookies. The host that serves the files may keep ordinary request logs. We do not add a tracking script on top of that.
Ad slots are empty boxes with a fixed height. No advertising script is loaded, so no ad network cookie is set by this site in this version. If ads are added later, this page will name the provider and the choices you have.
