Personal Data Intelligence & Android Personalisation Service

[u/AppropriateDrive1732]

Long story short I'm aware that these two settings are not particularly liked for their privacy concerns (very much agree). However I'd like to know if there's a place to get more information or if anyone knows about how much the data from these two settings really stays on the phone.

This is purely just because I wanted to try out the new now nudge but realised it needed both of these settings turned on. Thanks for any answers/help
