TubeScope does not collect, transmit, or store any personal data.

Your YouTube Data API key is stored locally in your browser using the extension
storage API. It is never sent anywhere except to Google's YouTube Data API when
you request data.

Channel and video data retrieved from that API is processed and displayed
entirely within your browser. It is never uploaded anywhere.

Your saved channel watchlist is stored locally in your browser.

There is no backend server, no analytics, no telemetry, and no third party
services of any kind. The developer receives no data from you.

Uninstalling the extension removes all locally stored data.
