How to cancel Pinduoduo's automatic access to Apple's mobile phone calendar? It's no use turning off the Pinduoduo message alert, it will automatically appear on the calendar.

Just turn off the app switch that doesn't need to access the calendar here.

But my Pinduoduo doesn't automatically access the calendar.

There is no such application in privacy.

So maybe some function of your Pinduoduo triggered the access mechanism.

In this case, Pinduoduo will be automatically added to the privacy calendar.

Or calendar access push of other applications.
