These data are used only for the user-triggered clipping feature. Page content is processed locally and sent directly to the user's configured EdgeEver instance. When the token includes `ai:generate` and the workspace has a default model, that instance sends the caption text to the configured model provider. The extension does not send the page or its audio to any other third party.
