Is Zotero to Overleaf Local Sync safe?

Clean risk

Zotero to Overleaf Local Sync fetches Zotero Better BibTeX exports and inserts them into Overleaf projects.

On Overleaf project pages, the extension reads a Better BibTeX export URL from the editor, asks its background script to fetch that local Zotero endpoint, and writes the returned text into the document. This can place Zotero bibliography data into files opened on Overleaf as part of the sync workflow.

Where it sends data

Destinations our analysis observed Zotero to Overleaf Local Sync contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • *.overleaf.com

    Zotero to Overleaf Local Sync sends data to *.overleaf.com. No other extension we have analysed sends data here.
