Chat Privacy Screen by Quietfield · Last updated: 10 May 2026
This extension stores nothing about you. Your messages, contacts, and media are never read, touched, or transmitted. Only your blur preferences are saved — locally, on your device, by your browser.
What this extension does
Chat Privacy Screen is a Chrome browser extension published by Quietfield that applies CSS blur filters to elements on WhatsApp Web (web.whatsapp.com), Telegram Web (web.telegram.org), and Arattai (web.arattai.in). This lets you use these chat apps on a shared or public screen without other people seeing your conversations. Hovering over a blurred element reveals it; moving away re-blurs it.
Data we collect
We collect no personal data. The extension does not read, copy, store, or transmit any message content, contact names, profile pictures, or any other information from any of the pages it operates on.
Data stored locally on your device
The extension saves three preference values in your browser’s local extension storage (chrome.storage.local):
- Privacy mode on/off — a boolean (true or false)
- Blur targets — four booleans controlling which elements to blur (names, messages, profile pictures, draft input)
- Auto-lock timeout — an integer representing seconds (30, 60, or 300)
These values contain no personal information. They are stored entirely within your browser and are never transmitted anywhere — not to us, not to any server, not to any third party.
Why the extension needs access to these sites
When you install this extension, Chrome shows a permission notice for each supported site. This is Chrome’s standard warning for any content script that interacts with a page. In practice, the extension uses this access solely to:
- Add and remove CSS class names on the
<body>element to activate blur filters - Inject a small status badge so you can see when privacy mode is active
The extension does not read the text of your messages, does not intercept any network requests, and does not modify any data sent to or from any site’s servers.
Third-party services
This extension contacts no external servers. There is no analytics, no telemetry, no crash reporting, and no advertising. No data of any kind is sent to us or to any third party.
Security
The extension enforces a strict Content Security Policy that blocks eval, inline scripts, and remote script loads. All logic runs entirely within your browser. The source code is open source and publicly auditable.
