🔬 Pure Mathematical Rubric & Open Data

Public Methodology & Integrity Firewall

Credibility is our only asset. We operate under a strict separation between scoring, citations, and funding. No brand can pay to alter, improve, or sponsor their score.

The Integrity Firewall Policy

Core Principle:

Grades are Shoptegrity's opinion, reached by applying this published rubric to documented facts: ownership structure, SEC financial filings, and sourced regulatory records. The scoring engine has zero read access to commercial or affiliate data.

Where the Numbers Come From
