Blur for WhatsApp Web: Privacy & Hide Chats

Privacy for WhatsApp Web: blur and hide chats, names, photos and messages from onlookers and screen sharing. Hover to reveal.

A privacy extension for WhatsApp Web. It blurs and hides your chats, names and photos from anyone who can see your screen, and shows them again the moment you point at them. Anyone walking past your desk can read your whole chat list: who writes to you, what they said, and how often. Sharing your screen in a meeting shows the same thing to everyone on the call. This extension keeps it private without getting in your way. CHOOSE WHAT TO HIDE • Last message, including read receipts, attachment icons and emoji • Contact and group names • Profile photos, group icons and initial avatars • Unread message badges • Timestamps • Messages in the open conversation Each one has its own switch, so you hide only what matters to you. Blur strength is adjustable from 1 to 8 pixels. HOVER TO REVEAL Nothing is hidden from you, only from people looking over your shoulder. Rest the mouse on a row and it clears after a brief pause, so sweeping across the list reveals nothing. Move away and it is blurred again at once. READY FOR SCREEN SHARING Press Alt+Shift+B to switch everything on or off without opening the popup: instant privacy right before you share your screen. You can change the key in your browser's extension shortcut settings. LOCK IT WHEN YOU STEP AWAY This extension stops glances; a password stops someone who sits down at your computer. One click in the popup takes you to WhatsApp Web's own app lock, where you set a password. The extension never sees it. STAYS OUT OF THE WAY • The toolbar icon shows your unread count, so the tab can stay in the background • Click the icon from any other tab to jump straight to your chats • If a site update ever stops the blur from applying, the icon warns you instead of failing silently • Optionally hides everything again after a minute without mouse or keyboard activity • Light and dark themes, thirteen languages PRIVACY BY DESIGN • No data collection of any kind • No network requests: there is no server • No analytics, no telemetry, no ads, no tracking • Never reads your chats or messages. The only thing it reads is the unread count in the tab title, and you can switch that off • Runs on web.whatsapp.com and nowhere else • One permission (storage), unminified code, no remote code HOW IT WORKS A single stylesheet does the work. Instead of blurring individual pieces of text, each rule covers the container that wraps the information, so nothing slips through: reaction text, attachment labels and emoji are all covered. --- Independent project.
