LineageOS

LineageOS is an operating system for smartphones, tablet computers, and set-top boxes, based on Android with mostly free and open-source software. It is the successor to the custom ROM CyanogenMod, from which it was forked in December 2016 when Cyanogen Inc. announced it was discontinuing development and shut down the infrastructure behind the project. Since Cyanogen Inc. retained the rights to the Cyanogen name, the project rebranded its fork as LineageOS.
Lineage OS is only partially free and open-source, that means from what I know, that you can’t really say 100% if there’s some data collection or not. How can we then say it is trade-free? I’d give 2/5 blocks because of that. The preinstalled apps, that LineageOS comes with, are listed here: https://en.wikipedia.org/wiki/LineageOS#Preinstalled_apps – I can’t judge if all of them are trade-free, for example if the weather app cLock uses a API from a trade-based service that you need.
