React native - facebook tracker in regular android build

Question

I have an app in production built with react native for android. There are no 3rd party plugins for tracking, logging in, or any of those sorts.

Recently DuckDuckGo app had a tool to implement others apps blocking trackers using VPN redirection.

And it comes to my attention that it is blocking now Facebook. I am not very comfortable with that and I can not find any info whatsoever on this.

Does anybody have some insight into this?

One option that you can do is to download Flipper , debug your app's.network traffic with it, and see if you find any requests that are going to Facebook's servers. DuckDuckGo is probably doing the same: it monitors outgoing requests and alerts you if any requests happen to the popular data collectors, like Facebook or Google. Without you inspecting the traffic yourself, it's pretty hard to guess the culprit.
