Kaita records the HTML of a page only while you have clicked Record changes on that page, and only for that tab. Snapshots are stored in the browser's local IndexedDB on your device. Nothing is transmitted anywhere: the extension makes no network requests of its own, has no analytics, no accounts and no third-party services. Clear a tab's history with Clear collected history, or remove everything by uninstalling the extension.

The Page tab in the viewer renders a snapshot in a sandboxed frame; the frame may load stylesheets, images and fonts referenced by the snapshot from the original site, exactly as a normal visit to that page would.
