I don’t know, because as far as I know, there is no documentation for Privacy Guard. Or is there something like that?
So far, I couldn’y find any myself. But I’ll ask around.
I did read a post on Reddit by a member of the LineageOS team, stating that Privacy Guard is based on AppOpsManager. Not sure if that helps or sheds any light.
Would be interesting whether other apps suffer from from the same problem.
On my phone it’s only ICSDroid that fails to behave properly.
I’m also keeping in mind that it could be something on my phone. I tried adding an ICSDroid account from the accounts menu. That brings me into the app, allowing me to add a calendar resource, but no ICSDroid account will show when that process is finished. That’s odd, but I guess something outside the app.
Or do I need to disable Privacy Guard completely?
That, I found out, is not achieved easily. Once enabled during initial phone setup, it can only be turned off per app.
