It&#x27;s even worse - simply using the same wifi point as your other Google accounts or even your friends will deanonymize you.<p>Trustable local software (so <i>not</i> GApps&#x2F;Android) and a mix network is the only way to get anonymity.<p>I&#x27;d personally like to see communication apps that use TOR for messaging, with the option to explicitly break anonymity for voice calls - leaving your location untracked most of the time.
