Is Ouriginal for Google Classroom Extension safe?

Ouriginal for Google Classroom transmits Google OAuth tokens and student profile data to its backend for plagiarism analysis.

When a teacher signs in, the extension forwards a Google OAuth access token to gsuite-urkund.appspot.com to authenticate with the Ouriginal service. It then retrieves student profiles and submission file IDs from Google Classroom and sends them to the same backend, where plagiarism analysis is performed. Both behaviors are the core product function and are marked as expected for this type of academic integrity tool.
