You can choose to manually archive or unarchive a review at any time. Hover over the review title to select the option 'Archive' or 'Unarchive.' One of the main purposes of the archive option is to de-clutter your current reviews page. It is useful if you are no longer actively involved in a review or a review is complete. An archived review will not be archived on co-reviewer's accounts; it will only apply to your account. 

Your review will not automatically move to the archived tab if your Covidence subscription expires.
