Tubeleau version 0.2.5 runs on supported YouTube pages after you open it.
It reads the video links, video IDs, titles, channel names, thumbnail URLs, and other visible metadata needed to render a temporary Grid, Feed, or Stack view. That page data remains in the current tab session. Tubeleau does not create an account, save a library, run analytics, or send that metadata to Wielder servers.
Tubeleau does not download video or replace playback. Selecting a video uses YouTube’s standard page and player. YouTube continues to receive the requests needed to provide its page and playback under Google’s own terms and privacy practices.
Closing the Tubeleau view or leaving the page discards its temporary arrangement. Removing the extension removes its code from Chrome.
