I asked Siri to remind me to purchase some personal items at the pharmacy, and right at that time the reminder appeared, I got an awkward phone call from a family member asking me why my reminders appeared on their phone.
I discovered this when I opened "reminders" on the Mac. Somehow the only reminder list I have is "Family". That means every alert I had appeared on their devices. every.one.
Besides being exposed to a complete lack of privacy, how can I stop default reminders, of any source, from appearing on the family iCloud group?
Examples: Email, calendar, events, etc

Settings → Reminders → Default List. This is where you can choose the list you wish to store reminders when you don't specify a location at the time of creating the reminder.
