Stereo to Surround Lab is a Chrome extension designed to process browser-tab audio locally and experiment with stereo-to-surround playback.
When the user explicitly starts audio processing, the extension accesses audio from the selected browser tab.
Audio is processed in real time on the user's device. The extension does not record, permanently store, upload, or transmit captured audio to external servers.
The extension saves user-selected audio settings, including rear-channel volume and delay, using Chrome's extension storage.
These settings are used only to restore the user's preferred configuration.
The extension does not sell or share captured audio or user information with third parties.
The extension does not use advertising trackers, analytics services, or external data-collection services.
Users can start and stop audio processing through the extension's controls. Users can remove stored preferences by clearing the extension's data or uninstalling it.
This policy will be updated if the extension's data-handling practices change.
