Margiqo, the browser-only Shopify margin scanner

Why it surfaced

This prototype makes a clear privacy promise: files are processed locally in the browser and disappear when the tab closes. It also shows its working, exposing the arithmetic behind findings while explicitly excluding returns, shipping, payment fees, and ad spend from the analysis.

Margiqo reads Shopify order and product-cost CSV exports to identify discount leakage and sales made below cost.
