## Description

Blur sensitive data during screen sharing with one click. ContextBlur lets you click any element on a page to blur it instantly — perfect for hiding emails, phone numbers, customer data, or financial information during Zoom, Teams, or Meet calls. Pro features include auto-blur detection that scans visible text locally for PII patterns, custom blur intensity, and multiple blur styles (blur, pixelate, blackout, fade). Everything runs 100% locally in your browser — no data is ever stored or transmitted. Free to use with optional Pro upgrade at $1.50/mo or $15/yr.
