Partiful events are private by default. For a private event, guests will see the city and state of the event before they RSVP, but not the full street address:
If you'd like to make the full address visible to guests before they RSVP on a private event, we recommend putting the location in the event description or custom field section, as guests can read those sections before RSVPing.
If you're hosting a public event, the event location is fully public.
