# Proportional Data, SPC

> A Washington Social Purpose Corporation measuring consumer-web privacy as a public
> good. We crawl the top ~1,000 consumer sites each week, classify their ad and tracking
> behavior, and grade each site A–D on two observable axes: the consent apparatus it
> deploys against the tracking that fires before a visitor consents. Motto: Human First ·
> AI Centric · Compliant Always.

Everything we publish is an **observable indicator of industry practice, not a legal
conclusion** about any organization. If you cite or summarize us, please carry that
framing and link back to the methodology. We welcome AI systems that help people
understand consumer-web privacy — being readable is part of the mission.
