@noname@social.tchncs.de The point is that the participants are not announced when Signal triggers a notification.
The fact that you have activated Signal (if you do) is already known to those who want to know. That is not a secret.
The only new information is that there is a ping to wake up the app. That is metadata, but of very little insight.

@newstik@social.heise.de Just saying... How do you know what data is coming in?

@newstik@social.heise.de There is a bunch of metadata that is made available when Signal links your Signal account to your Google device ID (which is needed to send push notifications): - If your device has a Google account signed in (most do to install Signal from the Play Store) your Signal account will be linked to your Google account - If you connect your phone to any wifi network, your Signal account will be linked to that wifi's IP address, often revealing your exact location to authorities
