WhatsApp Privacy — Blur & Lock helps you keep WhatsApp Web private when working, studying, presenting, streaming, or sharing your screen.

You can reveal content only when needed, then hide it again automatically. It also includes an optional screen lock for WhatsApp Web, so you can protect the page with a local password when you step away from your computer. No account. No sign-up. No cloud storage. Your settings stay on your device. ━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY FOR WHATSAPP WEB ━━━━━━━━━━━━━━━━━━━━━━ WhatsApp Web is convenient, but it can expose private conversations when someone walks behind you, looks at your monitor, or sees your screen during a call. WhatsApp Privacy — Blur & Lock is designed for everyday situations where you want to stay connected without leaving your conversations visible. Useful when you are: ✓ Working in an office ✓ Sharing your screen in a meeting ✓ Presenting on Zoom, Google Meet, Microsoft Teams, or OBS ✓ Studying in a classroom or library ✓ Using a shared workspace or co-working desk ✓ Working in cafés, airports, or public places ✓ Managing customer conversations from a support desk ✓ Recording tutorials or live streams ✓ Keeping personal chats hidden from casual glances Instead of closing WhatsApp Web completely, you can keep it open with sensitive content blurred. ━━━━━━━━━━━━━━━━━━━━━━ 👁️ BLUR MESSAGES UNTIL YOU HOVER ━━━━━━━━━━━━━━━━━━━━━━ The main feature is simple: your conversations are hidden behind a blur effect until you choose to reveal them. You can blur: ✓ Message bubbles in open chats ✓ Incoming and outgoing messages ✓ Last-message previews in the chat list ✓ Contact names and group names ✓ Profile pictures and avatars ✓ Photos, videos, GIFs, and stickers ✓ Media thumbnails ✓ Gallery viewer content ✓ Message input text while typing ✓ Group participant names ✓ Sidebar content and visible chat details When hover reveal is enabled, you can move your mouse over one specific area to read it. Move away, and it becomes private again. This helps you check a message without exposing the rest of your chat window. ━━━━━━━━━━━━━━━━━━━━━━ 🧩 CHOOSE WHAT GETS HIDDEN ━━━━━━━━━━━━━━━━━━━━━━ Different users need different levels of privacy. Some people only want to hide message previews. Others want the full interface protected during screen sharing. The extension lets you choose which parts of WhatsApp Web should be blurred. You can enable or disable privacy options for: ✓ Chat messages ✓ Chat list previews ✓ Contact names ✓ Group names ✓ Profile photos ✓ Media content ✓ Stickers and videos ✓ Message input field ✓ Header information ✓ Sidebar content You can also adjust the blur strength, so the interface can be lightly hidden or fully unreadable. ━━━━━━━━━━━━━━━━━━━━━━ 🖱️ HOVER TO REVEAL ━━━━━━━━━━━━━━━━━━━━━━ Hover reveal lets you read only what you need. For example, you can keep your whole WhatsApp Web interface blurred while revealing just one message, one chat preview, or one piece of media under your cursor. This is useful when: ✓ Someone is near your desk ✓ You are in a meeting ✓ You are sharing only part of your screen ✓ You want to read one message without revealing the whole chat ✓ You are switching between work and personal conversations You can choose between instant reveal and a smoother transition. ━━━━━━━━━━━━━━━━━━━━━━ 🔐 SCREEN LOCK FOR WHATSAPP WEB ━━━━━━━━━━━━━━━━━━━━━━ For stronger protection, the extension includes a full-screen lock layer for WhatsApp Web. When enabled, the lock screen hides the page until your local password is entered. Screen lock features: ✓ Lock WhatsApp Web with a password ✓ Lock instantly from the extension popup ✓ Auto-lock after inactivity ✓ Lock when the tab loses focus ✓ Choose your own inactivity timer ✓ Hide all chats behind a full-screen privacy layer ✓ Password stored locally as a secure hash This is helpful when you leave your desk, switch tasks, or use a computer in a shared environment. ━━━━━━━━━━━━━━━━━━━━━━ 💼 MADE FOR WORK, MEETINGS & SCREEN SHARING ━━━━━━━━━━━━━━━━━━━━━━ Screen sharing is one of the most common ways private messages get exposed. One open WhatsApp Web tab can reveal chat previews, names, photos, media, or incoming messages while you are presenting. The extension helps reduce that risk by keeping sensitive parts of the interface hidden. It works well for: ✓ Remote work ✓ Hybrid offices ✓ Sales calls ✓ Support teams ✓ Client presentations ✓ Online classes ✓ Webinars ✓ Live demos ✓ Screen recordings ✓ Streaming setups You can keep WhatsApp Web available without showing every private message on your screen. ━━━━━━━━━━━━━━━━━━━━━━ ⚙️ QUICK CONTROLS ━━━━━━━━━━━━━━━━━━━━━━ The extension is designed to be easy to control from the browser toolbar.

It does not modify your conversations. It only changes how sensitive content is displayed on your screen. You can use the extension to hide private information while keeping the interface usable. Examples: ✓ Hide chat previews while keeping the chat list visible ✓ Hide contact names during a presentation ✓ Blur media thumbnails in public places ✓ Hide message text while keeping timestamps and layout visible ✓ Reveal only the message you are currently reading ✓ Keep your draft message hidden while typing ━━━━━━━━━━━━━━━━━━━━━━ 🧰 OPTIONAL PRODUCTIVITY TOOLS ━━━━━━━━━━━━━━━━━━━━━━ In addition to privacy features, the extension includes optional tools for users who want more control over their WhatsApp Web workflow.
