In order to provide and ensure the quality of the Zotero server service, we store the following technical data:
Data associated with your account, such as login information (e.g. usernames)
Data associated with your sync activity, such as standard access logs that list IP addresses
Customized recommendations: server accounts may use Zotero library data to suggest, based on your preferences, works of scholarship that might be of interest.
None of this information is shared with any third parties; it is used only to keep the Zotero server running smoothly.
