What is the Screen Privacy Tool?
The Screen Privacy Tool provides an instant visual privacy overlay for your browser content when someone approaches your screen unexpectedly. Activate it with a keyboard shortcut or button click, and the tool overlays a dark, blurred, or distorted layer over the current page content — hiding it from shoulder surfers while keeping your session active.
This is a browser-based privacy shield designed for use in public spaces like coffee shops, airports, co-working spaces, and open-plan offices where screen visibility is a concern.
How to Use the Screen Privacy Tool
Activating screen privacy involves these steps:
- Open the Screen Privacy Tool in your browser on the page you want to protect.
- Click "Activate Privacy Shield" or press the configured keyboard shortcut to instantly apply the privacy overlay.
- The page content is obscured with a dark or blurred overlay that prevents screen reading from a distance.
- Press the shortcut again or click "Deactivate" to restore the normal view when privacy is no longer needed.
- Adjust the overlay opacity and blur intensity in the settings panel to match your environment.
Key Features
- Instant Activation: One keyboard shortcut toggles the privacy overlay on or off without disrupting your workflow.
- Adjustable Intensity: Control the opacity and blur level to balance privacy and ambient light conditions.
- Session Preservation: The privacy overlay is purely visual — your session, data, and active work remain intact underneath.
- Zero Server Contact: All overlay logic runs locally in the browser. Nothing is captured, recorded, or transmitted.
Common Use Cases
This tool is helpful for the following tasks:
- Public Working Environments: Hiding sensitive documents, emails, or financial dashboards when working in cafes or airport lounges.
- Open-Plan Offices: Quickly shielding screen content when colleagues walk past your desk during sensitive work.
- Shared Device Usage: Obscuring content between tasks when multiple people share access to the same workstation.
Frequently Asked Questions
Does this replace a physical privacy screen filter?
No. A physical privacy screen filter limits the viewing angle from both sides. This tool only provides a quick visual overlay for momentary use when needed, not a permanent side-angle shield.
Is my screen content captured when the shield is active?
No. The overlay is a CSS/canvas layer rendered locally. Nothing is captured, recorded, or transmitted at any point.
Can I use this while watching a video or using a web app?
Yes. Activating the overlay pauses visual exposure without stopping background processes. Deactivate to continue where you left off.
Does the keyboard shortcut work on all websites?
The shortcut works within this tool's page. For site-wide shortcuts across any tab, a dedicated browser extension would be required.
Privacy & Data Note
All overlay logic runs entirely inside your browser. No screen content is captured, recorded, or transmitted. The tool applies a visual CSS/canvas layer with zero external communication.
