1. Zero Data Collection & Zero Tracking
We do not collect, store, transmit, or sell any of your personal information, browsing history, or lecture activity.
- No Analytics or Telemetry: There are no tracking pixels or Google Analytics scripts inside the extension.
- No Account Access: We never read, access, or store your Physics Wallah passwords, student profile details, test scores, or payments.
- No Advertisements: The extension is 100% free and contains zero third-party ads.
2. Real-Time Audio Processing (Skip Silence)
The Skip Silence feature dynamically fast-forwards through teacher pauses and silent formula writing:
- How it works: The browser's native Web Audio API measures lecture output volume in real-time to detect quiet moments.
- No Recording: Audio and video are never recorded, saved, downloaded, or sent to any server.
- No Microphone Access: The extension never requests or activates your microphone.
3. Local Storage on Your Device
The extension only uses Chrome's standard chrome.storage.local API to remember your personal preferences:
- Custom video speed choices (e.g. 2.5x, 3.2x).
- Focus mode settings (hiding live chat or doubt boxes).
- Accumulated "Time Saved" counter.
Uninstalling the extension or clearing your browser extension storage removes 100% of these records instantly.
