Out of an abundance of caution, this software should not be installed on CCSU owned devices.  Grammarly takes a copy of any documents you are working on and uploads them to their cloud.  As Central does not have a formal agreement with Grammarly, there is no contracted data privacy safeguards in place.  As a work around, it is advised that Grammarly can work through a "browser extension".
