About Blind-Spot Pro – WCAG Contrast Checker

Blind-Spot Pro is a local-first WCAG contrast checker for Chrome. Inspect contrast problems, audit entire pages, review color pairs, preview visual simulation modes, and export useful reports without sending page data to a server. Free mode includes basic inspection, limited audit issue results, recent history, and favorite color pairs. Blind-Spot Pro unlocks unlimited issue reporting and history, advanced export formats, visual simulation, auto-fix, and batch-fix workflows. Checkout happens externally on Gumroad. After purchase, paste your Gumroad license key into the extension to activate Pro. Google is not the seller. The Pro upgrade is a $6.99 one-time lifetime purchase. There is no free trial and no subscription. Contrast analysis, history, favorites, and reports stay local in Chrome. The extension only contacts Gumroad to verify the license key and Uncommon Weather’s first-party legal service to record the user’s legal choice; page content is not sent to either service.
