Blur your WhatsApp Web and Telegram chats — without the audience.

The extension runs entirely in your browser. It adds CSS blur filters to WhatsApp Web, Telegram Web, and Arattai — covering four targets on each platform: contact and group names, message previews and chat bubbles, profile pictures, and the draft input field. Hover over any blurred element to read it; move your cursor away and it blurs again. An auto-lock timer re-blurs everything after a set interval, so stepping away from your desk doesn’t leave your conversations exposed.

Toggle blur on or off with a single click on the extension icon — or with the keyboard shortcut Alt+Shift+P without leaving the page. The shortcut works across all three platforms simultaneously. Each of the four blur targets can be enabled independently, so you can hide names and photos without touching message content, or blur only what matters in your specific situation.

Nothing in the extension touches your messages in transit. It does not intercept network requests or modify anything sent to any site’s servers. The only data it writes is your blur preferences and chosen timeout — three small values stored locally in your browser, never transmitted anywhere.

When to use it

The three most common situations: the coffee shop where you need to check messages while others are nearby, the open-plan office where a colleague can see your screen without trying, and the commute where reflections in glass make your screen readable to the person behind you. In each case, the extension stays on until you turn it off — nothing to remember or re-enable every time someone sits down.

It also covers less obvious moments: a screen-share call where your chat window is visible to everyone in the meeting, or a shared computer where the next person can scroll through the browser history and see a WhatsApp Web session left open. Privacy Mode handles both.

Permissions

The extension requests two permissions. storage saves your blur preferences locally — which targets are enabled and your chosen auto-lock timeout. sidePanel opens the settings panel in Chrome’s sidebar. That is the complete permissions list. No access to your tabs, browsing history, network requests, or any page content. The extension cannot read what is in your conversations — only CSS knows they are there.
