Does Apple notify users before renewing an auto-renewable subscription? When an auto-renewable subscription is due for renewal, does Apple notify the user ahead of time, via a notification or email? Or is their credit card charged without their knowledge?

I'm considering using auto-renewable subscriptions in my app, so I want to understand this.
Apple sends an email notifying the user about an upcoming auto-renewal about a month in advance.



SOURCE: I use apps that auto-renew.
