The Privacy Extension for WhatsApp Privacy is a free Chrome add-on designed to bolster user privacy while using WhatsApp Web, particularly in public settings. This extension effectively blurs messages, images, and profile information until the user hovers over them, ensuring that sensitive content remains concealed from prying eyes. The tool's primary aim is to offer a secure way to engage with WhatsApp without compromising personal information.

Key features include a screen lock that requires a password to access WhatsApp Web, customizable blurring options for specific elements, and a hover-to-reveal function that unveils blurred content. Users can also blur entire screens, message previews, images, and profile pictures, enhancing overall privacy. The extension allows for a tailored experience, enabling users to adjust settings based on their individual privacy needs.
