QuietBubble

QuietBubble is a mobile app (iOS/Android) that helps you understand and improve “privacy in place” at home, in hotels, Airbnbs, offices, and shared living. It runs quick, guided checks for common privacy leaks: audible speech through doors/walls, line-of-sight exposure through windows/peep holes, and device-based risks like unknown Bluetooth trackers nearby. Using your phone’s microphone and camera (with explicit consent), it estimates how easily conversations carry, flags obvious visual exposure points, and generates a practical checklist: where to add a door sweep, which curtain type actually blocks silhouettes, how to reposition desks, and what low-cost fixes work. It also includes a “Private Mode” routine for calls: prompts to close specific gaps, plays calibrated masking noise, and warns if your voice is likely intelligible outside the room. This is a combination traditional + AI app (AI for detection, scoring, and recommendations).
