Device Personalization Services is a system component which powers intelligent features across Android, whilst keeping your data private:

• Live Caption, which automatically captions media playing on your Pixel.
• Screen Attention, which prevents the screen from turning off if you are looking at it, without having to touch it.
• Improved Copy and Paste that makes it easier to move text from one app to another.
• App Predictions in the launcher, which suggest the app you may need next.
• Smart Actions in Notifications, which adds action buttons to notifications which let you see directions to a place, track a package, add a contact and more.
• Smart Text Selection across the system, which makes it easier to select and act on text; for instance, you can long-click on an address to select it and tap to see directions to it.
• Linkifying of text in apps.

Device Personalization Services uses system permissions to provide smart predictions. For instance, it has permission to see your contacts so that it can show you suggestions to call a frequent contact.
