According to the tracking scanner Exodus (can be found on F-Droid), which keeps an updated database on trackers and runs your installed app against its register, you can track what apps are tracking you and clues of how. Saw that Boost is tracking me and uninstalled it and went straight to Jerboa. Jerboa is pretty similar to good ole’ RedditIsFun-app and easy to use, so I am personally recommending it.
From F-Droid:
Exodus (Exodus show you trackers and permissions in apps installed on your device.) https://f-droid.org/packages/org.eu.exodus_privacy.exodusprivacy/
I’m not familiar with this interface, but it looks to me like it is saying Google was doing the tracking. Could this be tracking attempts made from a web view opened while using Sync, and not the actual Sync app itself? I want so badly to believe they are more privacy conscious than that. Love the app, been using it since it first came out for Reddit. Solo dev IIRC.
