With the analytics page, the admin of the workspace will be able to see each team member’s analytics based just on their work-related to-dos and the overall team analytics. If you are a member of the workspace, you will only be able to see your analytics based on both your personal to-dos and your work to-dos.
With the team feed, the team members will be able to see your todos if you choose to share it with them on the team feed. The choice is really up to you!
