Lectio Sync has no analytics, advertising, telemetry, or hosted backend. It reads timetable pages from the user’s existing Lectio session. After explicit authorization, selected timetable fields are sent to Google Calendar. Firefox stores a revocable Google OAuth refresh token locally. No Lectio password, MitID data, or cookies are collected. Disconnecting removes local connection state and the Firefox refresh token.
