Core Privacy

Core

Smart Content Blurring

Independently blur the sidebar chat list and message bubbles. Choose exactly what gets hidden - everything else stays fully visible.

• Blur sidebar chat rows, message bubbles, or both simultaneously
• Archived chats and group sender avatars are included in the blur scope
• Blur is applied via pure CSS - no performance impact on WhatsApp Web

Hover to Reveal

Temporarily unblur any chat row or message bubble with a mouse hover - without disabling privacy mode globally.

• Works on sidebar rows, message bubbles, and search results
• Blur instantly reapplies when the mouse leaves the element
• Can be toggled on or off from the settings panel

Adjustable Blur Intensity

Fine-tune the blur strength from 1px (subtle) to 20px (heavy). Find the perfect balance for your environment.

• Slider-based control from 1px to 20px
• Setting persists across browser restarts
• Works independently for sidebar and message areas

Dynamic Content Detection

A persistent MutationObserver monitors WhatsApp's DOM and applies blur to newly injected messages and chat rows instantly.

• New messages are blurred the moment WhatsApp injects them
• Works through WhatsApp's SPA navigation (no page reload needed)
• Handles group messages, status updates, and archived chats

Smart Detection

3 features

Smart

Auto Screen Share Detection

Automatically enables privacy mode when you start sharing your screen. Reverts to the previous state when sharing ends.

• Supports Google Meet, Zoom, Microsoft Teams (enterprise & personal), and Cisco Webex
• Intercepts the browser's getDisplayMedia API - no polling required
• Only auto-enables if the extension didn't already have blur on

Search Results Blur

When you open WhatsApp's search panel, matching result rows are blurred alongside the sidebar, preventing leaks during search.

• Blurs both chat names and message preview snippets in results
• Hover-reveal works in the search panel too
• Section headers ("Chats", "Messages") are excluded - only result rows are blurred

New

Notification Privacy

Hides message content from browser push notifications while privacy mode is active.

• Notification title is replaced with "New WhatsApp Message"
• Body text replaced with "Privacy mode is active."
• Works by intercepting the browser's Notification API - no WhatsApp changes needed

Keyboard & Shortcuts

3 features

Fast

Ctrl+Shift+O Toggle

Toggle privacy mode from any browser tab with a single keyboard shortcut - no popup interaction required.

• Works from any open tab, not just the WhatsApp Web tab
• State syncs immediately to all open WhatsApp Web tabs
• Shortcut can be customised in your browser's extension shortcut settings

New

Panic Overlay (Ctrl+Shift+P)

Instantly covers WhatsApp Web with a full-screen frosted-glass overlay. Press the same shortcut again to dismiss it.

• Overlay appears in under 100ms - faster than switching tabs
• Frosted-glass effect (backdrop-filter: blur 20px) completely hides content
• Overlay state persists through service worker restarts

Context Menu Toggle

Right-click the extension icon to enable or disable privacy mode without opening the popup.

• Menu title updates dynamically to show current state
• Recreated on browser startup so the label is always accurate
• Ideal on large monitors where the popup icon is far from the cursor

PIN Unlock

Set a 4-digit PIN required to disable privacy mode. Prevents accidental or unauthorized deactivation.

• PIN is stored as a SHA-256 hash locally - never transmitted or stored in plaintext
• A "Change PIN" option is available while PIN lock is active
• Resettable by clearing extension storage via browser settings

New

Scheduled Privacy

Define a daily time window and privacy mode activates and deactivates automatically every day.

• Uses the browser's alarms API - fires even when WhatsApp Web is closed
• Configurable start and end time in HH:MM format
• An inline warning appears in Settings if end time ≤ start time

Settings & Management

4 features

Last N Messages Visible

Keep the 1–5 most recent message bubbles unblurred while all older messages remain hidden.

• Configurable N from 0 (blur all) to 5 (keep latest 5 visible)
• Applies per-conversation so the freshest context is always readable
• Disabled in the UI when message bubble blur is turned off

New

Export Settings

Download all your preferences as a local JSON file. The backup stays on your device and is never transmitted.

• Exports blur level, schedule, PIN state, notification privacy, and all other preferences
• Runtime-only keys (session timer, active share flag) are excluded from the export
• One-click download - no account or cloud service needed

New

Import Settings

Restore a previously exported JSON backup instantly. Unknown or runtime keys are safely ignored.

• The popup reloads automatically after a successful import
• Invalid or malformed files show a clear error message
• Works across different browsers and browser profiles

Live Session Tracking

The extension popup shows a "Protected today" timer that tracks cumulative privacy-on time for the current calendar day.

• Timer ticks live every second while privacy mode is active
• Resets automatically at midnight each day
• Displayed as Xs, Xm Xs, or Xh Xm depending on duration
