About Blur for WhatsApp Web – Privacy, Hide Chats & PIN Lock
🔒 Blur for WhatsApp Web — Privacy blur & PIN lock
Blur for WhatsApp Web is a Chrome privacy extension that hides your WhatsApp Web chats from anyone nearby. Blur messages, image captions, and link previews instantly — then lock your session behind a PIN so only you can reveal them.
Built for open offices, cafés, shared computers, and screen sharing calls. If you use WhatsApp Web in a place where someone else might see your screen, this extension keeps your conversations private.

⭐ KEY FEATURES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🫧 One-click privacy blur
Toggle blur on or off instantly from the extension popup. Hides messages, image captions, and link previews so nothing slips through.
🔐 PIN lock for WhatsApp Web
Set a PIN to lock your session. When locked, a keypad replaces your chat view — no messages are visible until you unlock.
🚫 Full-screen lock option
Optionally hide your entire chat window the moment you lock, not just individual messages.
⚡ Lock now
Lock your session instantly with one tap before you step away from your desk or share your screen.
⏱ Smart auto-lock
Choose how WhatsApp Web re-locks itself:
• After a set time (timer)
• After a period of inactivity
• On every page reload
• Stay unlocked for the session until you tap Lock now
🛡 Brute-force protection
Too many wrong PIN attempts triggers a cooldown with a countdown timer, keeping snoopers locked out.
🔑 Recovery code
Forgot your PIN? Reset access safely using your one-time recovery code. Save it somewhere secure after setup.
🎛 Adjustable blur and idle settings
Control blur intensity and idle timeout using live sliders. Settings are saved automatically.

🛡 HOW TO USE IT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Install the extension and open WhatsApp Web.
2. Click the extension icon to blur your chats immediately.
3. Go to Settings → Security to set up your PIN.
4. Use "Lock now" to lock instantly, or let auto-lock handle it.
5. When locked, a keypad appears — enter your PIN to reveal your messages.
💡 Note: setting a PIN doesn't lock your current session right away. It activates on the next idle timeout, timer expiry, reload, or when you tap "Lock now." Save your recovery code somewhere safe before closing setup.
