Privacy Shield

What is Privacy Shield?

Privacy Shield is a Chrome extension designed to help protect on-screen content while you share your screen, present to others, or work in public spaces. It adds blur and masking controls so sensitive parts of a webpage are hidden from prying eyes.

The extension focuses on page-level privacy actions such as blurring the entire page, blurring specific elements on demand, and masking tab information during meetings.

Key Features

• Full-Page Blur Overlay: Activates a frosted-glass overlay that blurs the entire page, with an edge you can drag to reveal only the portion you need.
• Selective Element Blur: Allows you to blur individual webpage elements by holding Right Alt and clicking an element; blurred elements remain across page reloads.
• Meeting Mode for Tabs: One-click mode that masks tab titles as “Private Tab,” replaces favicons with a shield icon, and activates the overlay across all open tabs.
• Customizable Blur Settings: Lets you adjust blur intensity from subtle to opaque, and use Always Blur / Never Blur site lists to control where blur applies.
• Theme and Auto-Detect: Supports dark, light, or system theme selection and can auto-detect meetings via camera and microphone usage.
• Zero Data Collection (per extension listing): The extension is stated to work entirely within the browser, with no data collected, stored, or sent elsewhere.

How to Use Privacy Shield

1. Install the extension from the Chrome Web Store, then open the webpage you want to share or present.
2. Choose a privacy mode:
   • Use the full-page blur overlay to obscure everything on the page, or
   • Use selective blur to target only specific elements.
3. For screen sharing sessions, enable Meeting Mode to protect all open tabs at once by masking tab titles and activating the overlay across tabs.

Use Cases

• Video calls in shared environments: Blur sensitive sections of a page while you work on a call from a café or co-working space.
• Presenting to an audience: Use full-page blur to quickly conceal confidential information on slides or internal web dashboards before you expose the intended parts.
• Targeted redaction for web content: Hold Right Alt and click specific elements (such as personal fields, identifiers, or account details) to blur only those items.
• Avoiding tab-name leakage during sharing: Turn on Meeting Mode so tab titles show as “Private Tab” and favicons are replaced with a shield icon.
• Consistent privacy across reloads: Blur specific elements once and keep them hidden even if the page reloads, which is useful for frequently refreshed web apps.

FAQ

• Does Privacy Shield collect or send my data? The listing states the extension works entirely within your browser and that no data is collected, stored, or sent anywhere.

• Can I blur only part of a webpage instead of everything? Yes. You can use the full-page overlay with a draggable edge to reveal only the portion you want, or selectively blur individual elements by holding Right Alt and clicking.

• Will blurred elements stay hidden after a page reload? The listing says blurred elements persist across page reloads.

• What does Meeting Mode change? It masks tab titles to “Private Tab,” replaces favicons with a shield icon, and activates the overlay across all tabs.

• How can I control which sites get blurred? The extension includes configurable Always Blur and Never Blur site lists.

Alternatives

• Screen privacy masking tools (overlay-based): Extensions or desktop tools that blur the whole screen or portions of it during screen sharing; they typically differ in how granular the element-level control is.
• Password or session lock extensions: Browser extensions focused on locking or hiding the entire browsing session rather than blurring specific content on webpages.
• Text/image redaction utilities: Tools that focus on obscuring sensitive content (often for screenshots) rather than providing live, interactive blur overlays while you share.
• Other privacy-focused browser extensions: Extensions aimed at reducing exposure (e.g., hiding content in specific services) that may be more targeted to particular sites instead of providing general blur controls across webpages.
