Local and privacy note:
Saved highlights, notes, QA, collections, tags, source anchors, and export preferences are stored locally in your browser. There is no account sync or cross-device cloud archive in this release. Saved conversation text, notes, questions, answers, collections, tags, and exported content are not sent to a colooon server. Exports are generated locally by user action.
Known limits:
Saved items live in the browser's local extension storage. PDF export uses the browser print window. colooon does not claim that content is never sent anywhere: you may still manually submit text back into ChatGPT or manually export/share files.
