No. The extension is a citation formatter, not a reference manager - it doesn't store libraries, manage PDFs, or sync across devices. Use it alongside your reference manager: paste in identifiers, get citations, copy out. For a full reference workflow, scholar-sidekick.com offers batch export to BibTeX, RIS, EndNote XML, CSV, and Markdown.
The extension contains no content scripts. It does not read page contents, browsing history, or anything else from the pages you visit. It only ever sees the text you explicitly select and submit via the right-click menu. Selected text is sent to scholar-sidekick.com to produce the citation, then discarded - not stored, not used to train models, not shared. No analytics, no advertising trackers.
