Stop GMS Firebase Indexing from collecting all of the personal data
You can add stronger measures , since your device is rooted

First is Xprivacy Lua which does an excellent job of protecting your privacy and also Firebase Analytics amongst other trackers (XPrivacyLua needs EdXposed. For EdXposed installation on 10, see How to install EdXposed on Android 10 without triggering safety net)

Next, download Warden App from F-droid or Izzy's repo. It is specifically aimed at killing trackers and loggers (with a few exceptions). You can selectively use the app to work on your apps or apps plus system.


By turning developer options off, you are only hiding what's happening w.r.t Firebase.
In addition, see answer here How can I make an Android app &quot;forget&quot; that it installed on my phone before?
