Is LibrusPro - rozszerzenie do Librusa safe?

Clean risk

LibrusPro fetches student profile, timetable, grade, and attendance records from Synergia for its Librus features.

LibrusPro runs on Synergia Librus pages and uses internal extension messages to request school-related records from synergia.librus.pl. It stores the returned profile, timetable, grade, and attendance data in browser extension storage so its local features can display them.
