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/
As long as you are in the know and knowingly know what you are paying for it’s all good.
I personally wouldn’t because supporting them (by using or paying) will bump them up on App-store popularity lists when you search for “Lemmy” and that would only keep misleading more unaware people.
