About this extension
Blur, mask, and redact anything on your screen before you share it. BlurMask is the privacy blur extension that hides sensitive data on any webpage — customer emails, credit cards, revenues, API keys, and personal PII — so nothing private ever appears in your screen share, screen recording, or livestream.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔹 BLUR SCREEN SHARE ON ZOOM, MEET & LOOM
Start every call with confidence. Blur any dashboard, inbox, or CRM tab before you hit "Share screen." The blur is applied to the live page itself, so Zoom, Google Meet, Microsoft Teams, Discord, and OBS only ever capture blurred pixels — zero video editing, zero leaks.

🔹 HIDE SENSITIVE DATA IN ONE CLICK
Hover and click to hide emails, phone numbers, credit cards, revenue figures, invoices, addresses, and patient records. Your private data stays private while everything else on screen stays readable.

🔹 MASK TEXT IN CHROME, EDGE, BRAVE & FIREFOX
Mask any text or element on any webpage. Alt+B toggles the click-to-mask inspector, Alt+S blurs highlighted text, and right-click → "Blur Selected Text" redacts in an instant.

🔹 REDACT SCREENS YOUR WAY
Three privacy modes: smooth Gaussian blur, pixelate/mosaic, and blackout redaction bars — with an adjustable radius to match your presentation style.

🤖 SMART AUTO-REDACTION (PRO)
Automatically detect and blur emails, SSNs, credit cards (Luhn-validated), API keys, JWT tokens, and currency amounts the moment a page loads.

💾 BLURS THAT STICK
Blurs persist across reloads and tab switches. Save named presets like "Client Demo" or "Loom Recording" and switch them in one click.

🔐 100% PRIVATE BY DESIGN
No accounts, no analytics, no servers, no tracking. All blurring runs locally in your browser — your data never leaves your device.

❓ FAQ
• How do I blur a Zoom meeting? Install BlurMask, press Alt+B, click what you want hidden, then share your screen — Zoom only captures blurred pixels.
• Can viewers un-blur my screen share? No. Screen shares and recordings capture flattened pixels; the original text never enters the video stream.
• Does it work on Google Meet, Loom, and OBS? Yes — if it plays in your browser, BlurMask blurs it before capture.
• Does BlurMask see my data? Never. Everything runs 100% locally.

🛡 PERMISSIONS
"Read and change data on all sites" is required solely to apply blur styles to pages you choose, in response to your actions. Nothing is uploaded, ever.

Install free today and make every screen share safe to share.
