Infobesity does not collect, store, transmit, or sell any data. There is no analytics, no telemetry, no remote server, and no account.
To calculate a video's speech density, Infobesity reads the following from the YouTube page you are already viewing:
- the video ID, title-independent metadata, and runtime;
- the list of available caption tracks and the caption text itself;
- YouTube's own in-page client configuration values, which are required to request a transcript the same way the site's "Show transcript" button does.
All of these are read inside your browser tab, from youtube.com, in the moment you are watching the video.
It is used to compute a words-per-minute figure, which is displayed as a badge on the player. It is then discarded when the tab navigates or closes.
Infobesity:
- makes network requests only to
https://www.youtube.com, the site you are already on, and only for caption data; - uses no
storagepermission and writes nothing to disk; - has no background service worker and no remote code;
- sends no data to the developer or to any third party.
The extension requests a single host permission, https://www.youtube.com/*.
It is required because caption data must be requested from youtube.com with the
page's own session, which is only possible from within a youtube.com tab. No
other site is accessible to this extension.
Any change to these practices will be published in this document and reflected in the extension's Chrome Web Store listing before the change ships.
