Questions People Ask

Honest answers about how this works.

Is my personal weight data stored?

Great question. No. All calculations are performed entirely in your browser's local memory. No data is sent to external servers.

How exactly does the Shipping Weight calculator work?

Great question. It computes the dimensional (volumetric) weight using standard carrier divisors (e.g., 139 for inches/lbs, 5000 for cm/kg) and compares it to the actual weight, identifying the billable weight.
