There are some key things to keep in mind if you want to try to figure
out how to do truly anonymous tracking of installs for F-Droid:
-
F-Droid will not add user accounts ever
-
any kind of unique ID must be opt-in, never opt-out, and must be
generated only for the specific use (e.g. IMEI, IMSI, MAC address,
Android ID, etc cannot be used). -
the anonymity of the data must proven, not assumed. it only takes
33-bits of data to uniquely identify every person on the planet. There
are so many cases where organizations put data on the internet that they
believed had been “anonymized” only to find out it was trivial to
deanonymize with the right techniques
