facebook: Call and text history logging is part of an opt-in feature for people using Messenger or Facebook Lite on Android. This helps you find and stay connected with the people you care about, and provides you with a better experience across Facebook. People have to expressly agree to use this feature. If, at any time, they no longer wish to use this feature they can turn it off in settings, or here for Facebook Lite users, and all previously shared call and text history shared via that app is deleted. While we receive certain permissions from Android, uploading this information has always been opt-in only.
We introduced this feature for Android users a couple of years ago. Contact importers are fairly common among social apps and services as a way to more easily find the people you want to connect with. This was first introduced in Messenger in 2015, and later offered as an option in Facebook Lite, a lightweight version of Facebook for Android.
