What does Calendar Sync share or store?

By default, published events contain a generic Follow-up title, the appointment time and duration, and a link that opens the Visit in WitnessWork. Include names and addresses is optional and applies across your devices; turning it on adds those details to published events. Visit notes and Follow-up topics are never exported. Your chosen calendar provider may sync events to other devices, shared calendars, and widgets, so check that calendar's sharing settings before including details. WitnessWork manages only events it marked as its own and does not import your personal calendar appointments. A private iCloud record stores device names and opaque identifiers, publishing ownership, the connected calendar's name and account label, shared options, and event identifiers. Appointment content stays in the chosen calendar account. Each device's calendar identifier and connection state stay local and are separate from app-data sync and backup files.
