Yes, we have no restrictions on who can create an account.
We don't require students to create accounts or enter any personal information (as defined by COPPA) to play a game.
To create an account though, we do require some personal information, like an email. Please ensure that students have adult/parental consent to share these details if your rules require it.
We are committed to maintaining the highest level of privacy and security for our user's information. We only collect information to help us understand how people use Quizizz and what we can do to improve the experience for our users. Nothing else.
