Local Storage & Privacy Your saved highlights, notes, Q&A captures, collections, tags, source anchors, and export preferences are stored locally in your browser's extension storage. This release does not require an account and does not provide cloud backup or cross-device sync. Your saved conversation text, notes, questions, answers, collections, tags, and exported content are not sent to a Colooon server. Exports are generated locally when you choose to export. Important Notes • Saved items remain in your browser's local extension storage and are not automatically synced across browsers or devices. • PDF export uses your browser's print window. • TO CHAT places saved content into ChatGPT's message box. You decide whether to submit it. • Any content you choose to submit to ChatGPT or manually export and share is handled by the destination service or recipient. Colooon does not control how that content is subsequently processed or shared.
