Is BookWidgets Google Classroom Integration safe?

Low risk

BookWidgets reads the user's Google account email from classroom.google.com and sends it to bookwidgets.com on panel open.

The extension scans the Google Classroom page on each load to find the user's Google account email address by inspecting DOM elements near account-management links. When the user clicks the BookWidgets button, the extension constructs an SSO URL at www.bookwidgets.com/sso/google and passes the collected email as the login_hint query parameter. The extension also appends its own runtime ID to injected CSS class names, which makes the ID readable by any script running on classroom.google.com.

Where it sends data

Destinations our analysis observed BookWidgets contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
