WhatsApp Privacy Shield

Password-lock WhatsApp Web and blur names, avatars, previews, chat text, media, and the compose box to prevent shoulder surfing.

WhatsApp Privacy Shield protects your WhatsApp Web tab from shoulder-surfing in offices, cafés, screen shares, and any shared space. Screen Lock — password-protect your tab. It locks automatically on every fresh page load and after a configurable period of inactivity, so you never forget to lock it yourself. Granular Blur — independently blur contact & group names, profile pictures, last-message previews, chat messages, media, and the message input box. Each reveals on hover so WhatsApp still works normally for you — just not for anyone glancing at your screen. Fast controls — lock instantly with a keyboard shortcut, or pause/resume all blur at once without touching your saved settings. Private by design — 100% local. No network requests, no analytics, no data collection, no remote code. Your password is never stored — only a salted hash. Runs only on web.whatsapp.com.
