Real-Time Sync

When you add, edit, or delete an event in Google Calendar, Calendox is notified straight away — no delays, no background polling. Your changes appear on connected calendars within seconds. Calendox also automatically refreshes its connection to Google in the background, so your sync stays live without any action from you.

Recurring Events & Exceptions

Repeating events sync just as you'd expect — the whole series, individual occurrences, and one-off edits. If you move a single occurrence of a weekly meeting to a different time, Calendox carries that change across to the connected calendar without touching any of the other occurrences.
