You're In Business
The project solves a genuine and relatable problem (WhatsApp privacy during screen sharing) with a non-intrusive solution. Technical execution appropriately utilizes standard Web Extension APIs. Current audience reach is minimal (~400 users) and there is no reported revenue, placing it in the minimal traction category, though market timing is highly relevant given widespread remote work.

Description
WhatsApp Web Privacy Mode is a free browser extension for Chrome, Firefox, and Edge that automatically blurs your chats, messages, and notifications the moment you start screen sharing - keeping your conversations private during meetings on Google Meet, Zoom, Teams, or Webex. It helps remote workers, professionals, and anyone who shares their screen avoid accidentally exposing personal conversations, with zero data collected and no account required.
Audience Reach
Currently reaching approximately 400 users across Chrome, Firefox, and Edge installs combined. The project is in early growth stage - organic discovery through browser store search is the primary channel so far, with no paid promotion to date. Given that WhatsApp has over 2 billion active users and screen sharing is now a daily routine for remote workers worldwide, the addressable audience is enormous and largely untapped.
Target Users
Remote workers on daily video calls
Developers and designers who demo products live
Teachers and educators sharing screens with students
Streamers and content creators recording their desktop
Anyone who's ever had that sinking feeling mid-screen-share
