Hi All, this worked for me.
In your iPhone/iPad, go to Settings > Privacy > Calendars ... check which Apps are accessing your Calendar - for e.g. if you use an AccuWeather app, when you first installed it, it would have asked for access to your Calendar ... if the the button is switched to "On" ... the weather app will post the temperatures (Min/Max) of the day in your Calendar.
- As the data appears in your Calendar, it's likely going to be replicated to everyone else's Calendar that you share an iCloud account with.
> Switching off the button in the Weather app, no temperatures appear in my Calendar.
- Do the same with the Stock app, switch the button to "Off", so it cannot access your Calendar/Contacts.
> In your iPhone/iPad, go to Settings > Privacy > Contacts ... check which Apps are accessing your Contacts ... turn off the ones you do no want the data fed into your Contacts.
Hope that helps.
