This page explains how Number Ninjas users can manage Google-connected data.
Disconnect and revoke access
Teachers can stop using Classroom in Number Ninjas by revoking the school authorization in General Settings. You can also remove Number Ninjas from your Google Account connections at Google Account permissions. Number Ninjas stops using the refresh token when the teacher account is deleted and attempts to revoke it.
Delete and export
Use the account deletion page to delete your Number Ninjas account and applicable local data. Teachers can request a student export from the student detail page. Schools, parents, and students can request additional access or an export by contacting privacy@yinyang-interactive.com.
What Google retains
Coursework already posted remains in Google Classroom and must be managed there by the teacher or school. Number Ninjas does not store Google passwords. See the Google User Data section for fields, purposes, storage, sharing, and deletion details.
