What Gets Anonymized?#

Attendee and organizer names
Comments and categories
Technical properties are preserved for bug reproduction:
Dates and times (DTSTART, DTEND, DUE)
Recurrence rules (RRULE, RDATE, EXDATE)
Metadata (STATUS, PRIORITY, SEQUENCE)
Timezones (complete VTIMEZONE components)
See the Python API for the complete property reference table.
