Lectio Sync troch Johannes Peulicke

Lectio Sync helps Danish students keep their Lectio timetable in a dedicated calendar. Sign in on the real Lectio website, connect Google Calendar, and let the add-on add, update, or mark cancelled modules.

The add-on is local-first. It has no advertising, analytics, telemetry, crash reporting, or hosted backend. It never asks for a Lectio password, automates MitID, or reads browser cookies directly. If Lectio returns an unexpected page or an expired session, synchronization stops before calendar changes are made.

After the user explicitly connects Google Calendar, selected timetable fields are sent directly to Google so the add-on can create and update the dedicated calendar. Firefox stores a revocable Google OAuth refresh token locally so background synchronization can continue after Firefox restarts. No timetable data or OAuth token is sent to Lectio Sync or an analytics service.

Features:

• Sync current and upcoming timetable weeks
• Update changed modules without duplicates
• Mark cancellations and notify the student
• Choose which timetable fields are copied
• Keep homework disabled unless enabled
• Disconnect without deleting the calendar
