When schools use Makers Empire, they have the option to provide Personally Identifiable Information (PII) about students, or they can opt-out of doing so.
Makers Empire can be used completely anonymously and only requires a username and password, which does not need to reflect the user's real name.
Teachers can optionally create accounts and supply student names and emails, which can make class management easier, but it is not essential.
