Restricted content is potentially sensitive content about an individual. Restricted content can be marked as Restricted or Restricted+ depending on the sensitivity of the content. Restricted and Restricted+ content may occasionally be stored in Google Issue Tracker. To mitigate the risk of this information being visible, content in Google Issue Tracker that contains or is suspected to contain sentitive content will be marked with a restricted flag. This restricted flag will restrict access so that the content can only be viewed by those with a business need (and never by the general public). Attempts to access content marked as restricted (both successful and unsuccessful) will be logged and auditable.
