Hello there, i tried to search in matrix logs and in the FAQ under "What kind of connections do the OS and bundled apps make by default?" but i haven't found what i was looking for.
I get that IMSService is/could be used to download carriers configs from 3gppnetwork.org (and others idk?) for services such as volte and others but since a while i have been wondering what kind of data do it send to the second domain, a google firebase one, once i tried to look at the source code but i haven't found it on graphene os github so i gave up, now i searched again and not sure if i understand right but is the app is pulled from google rom ? It's not on github, I went to the aosp repo and found it there, while i don't understand what the code is doing, forgive my ignorance, i can read stuff about FirebaseMessaging which seem related, so i was wondering what data is sent out to google or for which feature, i can see that it's not much data and rarely, but i was curious about it since a while. Thanks for your work!
