When participants with "student" level access view each others user profiles they see most of the information entered. As this could include a
range of contact, address and access information there may be concerns about privacy and compliance with data protection legislation.

The good news if you're concerned about this is that the site administrator can configure the site so that some of the relevant fields are hidden from other students (the course facilitators will still see the information when they view the user's profile).

Navigate to the following setting from the Site Administration block: Users > Permissions > User policies: Hide user fields, click the required fields and save.
