Calendar Chats in OurCal are end-to-end encrypted messaging channels that enable calendar members to chat together in one place and coordinate plans securely. Calendar Chat’s are also home to all the important notifications around your calendar. You can see a timeline of when events were added and when there’s new activity in Event Threads, along with any discussion that has happened between members. As with all data in OurCal, Event Chat Threads are fully end-to-end encrypted for your privacy.
