Would that be “Traffic Monitor & 4G/5G Speed” app by Treconite? If so, yes, Aurora says it does not have trackers but on the one-line listing it says “Requires GSF”. That there implies it will be doing some kind of contact with Google in some way. In what way I don’t know.
App Manager shows it has four internal trackers (starting with
com.vodafone.netperform.runtime...) and probably necessary but will check with them blocked first.
LOL, I guess they are necessary. App crashes with those blocked. Hence why they’re not listed. Like to double check anyway.
InviZible Pro shows Traffic Monitor consulting a bunch of IPs linked to
firebaseinstallations.googleapis.com. I guess that explains the Google stuff. Maybe.
Not to mention, if you have Cloud Messaging on in microG the app will prompt for push notifications.
