MaskShare — Blur & Hide Sensitive Data Chrome extension security report

MaskShare lets you blur, hide or black-out any sensitive information on a web page — in one click — so you can safely share your screen, record a demo, or take screenshots without leaking private data. Zoom, Google Meet and Microsoft Teams only blur your webcam background — not your shared screen. MaskShare fills that gap: it hides the sensitive parts of the actual page you're showing. PERFECT FOR • Sales & support teams demoing a CRM, dashboard or ticketing tool • Finance, ops and HR sharing spreadsheets or internal tools • Developers and IT screen-sharing with API keys, tokens or config values in view • Creators recording tutorials, screenshots and screencasts • Anyone who screen-shares and cares about privacy and GDPR HOW IT WORKS • Click "Mask an element", then click anything on the page to blur it instantly • Save a profile per site — MaskShare re-applies it automatically on your next visit, before the page even renders, so nothing flashes on screen • Keyboard shortcut (Alt+Shift+M) to hide or show everything during a call • Hold Shift and hover to briefly peek at a hidden value AUTOMATIC DETECTION (PRO) Automatically find and mask, on any site and in any language: emails, phone numbers, credit/debit cards (Luhn-validated), IBANs, amounts, postal addresses, IP addresses. CUSTOMIZE THE MASK (PRO) Choose blur, a solid censor bar, or strikethrough. Adjust blur strength so bold text can't be read through. Pick your color. EVERYTHING STAYS IN YOUR BROWSER All masking and detection run locally on your device. To find an email or a card number, MaskShare reads the text of the page you're on — that's unavoidable — but the analysis happens entirely in your browser's memory. Nothing is uploaded, nothing is stored, and we never see it. MaskShare has no analytics, no tracking, no cookies and no ads. The only network request it ever makes is validating a Pro license key. AVAILABLE IN 8 LANGUAGES English · Français · Español · Deutsch · Italiano · Português · 中文 · 日本語 FREE & PRO Free forever: manual masking, per-site profiles, keyboard shortcut.
