RedactShield: Blur & Redact for Screen Share

About

Stop leaking private data during demos, screen shares, and recordings.

RedactShield hides sensitive information on any web page in one click — customer names, revenue, API keys, emails, account numbers, anything. Built for sales engineers, founders, support teams, and creators who share their screen on real, logged-in dashboards.

WHY REDACTSHIELD IS DIFFERENT — REAL, DEEP DOM REDACTION

Most blur extensions just apply a CSS filter, so the data is still sitting in the page — anyone can right-click → Inspect Element and read it, and it can flash on screen during a recording. RedactShield's deep redaction actually replaces the text in the page with block characters and keeps the original only in your browser's memory. Inspect the element and you see ███, never the real value.

PRIVACY FIRST

RedactShield runs entirely on your device. It does not collect, transmit, or sell your browsing data or page content. No host permissions are requested at install — you grant access per site, only when you choose. The only network request is license verification with Gumroad, made only when you activate a paid license.
