Is Ultra Volume Booster safe?

Ultra Volume Booster captures tab audio to amplify volume and sends usage telemetry to Google Analytics on startup and hourly.

The extension uses the tabCapture API to obtain a raw audio stream from the active browser tab, routing it through a Web Audio gain node to boost playback volume. On startup and every 60 minutes, it fires page_view events to Google Analytics (measurement ID G-C1TVPBK3F8), including page_title and page_location, tied to a persistent UUID stored in chrome.storage.local.
