WhatsApp Privacy Guard is a Microsoft Edge browser extension designed to help users protect their privacy while using WhatsApp Web.
The extension applies visual blur effects to selected content displayed on WhatsApp Web, including profile pictures, contact names, message previews, conversation messages, and media.
WhatsApp Privacy Guard is designed with a local-first approach. WhatsApp content is processed within the user’s browser and is not intentionally transmitted to the developer or to external servers.
WhatsApp Privacy Guard processes WhatsApp Web content locally within the browser to provide its privacy and blur features.
The extension does not use an external server to process WhatsApp messages or other WhatsApp Web content.
The extension does not use external AI services, analytics services, advertising trackers, or remote processing services.
Message classification, including the optional Smart Message feature, is performed locally using a deterministic pattern-based detection system.
To provide its functionality, the extension operates only on WhatsApp Web.
Depending on the user’s enabled settings, the extension may process content displayed on WhatsApp Web, including:
This information is processed in the browser to apply visual blur effects.
The Smart Message feature can locally analyze message previews and conversation text for predefined romantic expressions, words, nicknames, and emojis.
The detection system operates within the browser.
Message content used for detection is not intentionally sent to the developer, an external server, an external API, or an external analytics service.
The extension uses the browser’s chrome.storage.sync API to store user preferences.
The stored preferences include:

WhatsApp message content, profile pictures, contact names, conversation history, or media are not stored by the extension.
