Audible feedback on just how much your browsing feeds into Google.

By bert@hubertnet.nl / https://berthub.eu/

Makes a little bit of noise any time your computer sends a packet to a tracker or a Google service, which excludes Google Cloud users.

Demo video in this tweet

How to compile

You need a C++ compiler like gcc-c++ and CMake for compiling the binary.

You also need to install libpcaudio (libpcaudio-dev on Debian/Ubuntu, pcaudiolib-devel on Fedora/Red Hat).

Then run:

cmake .
make

How to run

Start as:

sudo tcpdump -nql | ./teller

And cry.

Data source

The list of Google services IP addresses can be found on this Google support page.

Note that this splits out Google services and Google cloud user IP addresses. However, it appears the Google services set includes the cloud IP addresses, so you must check both sets before determining something is in fact a Google service and not a Google customer.

To run on a single process on Linux

Or, to track a single process, fe firefox, start it and run:

sudo bpftrace netsendmsg.bt |
    grep --line-buffered ^$(pgrep firefox) |
    stdbuf -oL cut -f2 | ./cidr.py | ./teller

And cry.
