The Search for Ethical Apps: Let's start with governments

 Posted on September 1, 2022  |  Hans-Christoph Steiner

Governments across the world are moving services to mobile apps. The vast majority of these apps are only available in the Google Play store or in the Apple App store. Installing apps from these services requires users to agree to their terms of service. This means governments require their citizens to sign opaque and privacy invading contracts with foreign Big Tech in order to use digital services. This feeds ever more into Big Tech data control, filtering, and information bubbles. [Read More]

New Data Sources: API Key Identifiers and BroadcastReceiver Declarations

 Posted on December 15, 2020  |  Hans-Christoph Steiner

A central focus of the Tracking the Trackers project has been to find simple ways to detect whether a given Android APK app file contains code which tracks the user. The ideal scenario is a simple program that can scan the APK and tell a non-technical user whether it contains trackers, but as decades of experience with anti-virus and malware scanners have clearly demonstrated, scanners will always contain a large degree of approximation and guesswork.

εxodus ETIP: The Canonical Database for Tracking Trackers

 Posted on December 11, 2020  |  Hans-Christoph Steiner

There is a new story to add to the list of horrors of Surveillance Capitalism: the United States’ Military is purchasing tracking and location data from companies that track many millions of people. We believe the best solution starts with making people aware of the problem, with tools like Exodus Privacy. Then they must have real options for stepping out of “big tech”, where tracking dominates. F-Droid provides Android apps that are reviewed for tracking and other “anti-features”, and F-Droid is built into mobile platforms like CalyxOS that are free of proprietary, big tech software.

Free Software Tooling for Android Feature Extraction

 Posted on May 6, 2020  |  Hans-Christoph Steiner

As part of the Tracking the Trackers project, we are inspecting thousands of Android apps to see what kinds of tracking we can find. We are looking at both the binary APK files as well as the source code. Source code is of course easy to inspect, since it is already a form that is meant to be read and reviewed by people. Android APK binaries are a very different story. [Read More]

"Features" for Finding Trackers

 Posted on April 28, 2020  |  Hamilton Kaplan

One key component of the Tracking the Trackers project is building a machine learning (ML) tool to aide humans to find tracking in Android apps. One of the most important pieces of developing a machine learning tool is figuring out which “features” should be fed to the machine learning algorithms. In this context, features are constrained data sets derived from the whole data set. In our case, the whole data set is terabytes of APKs. [Read More]

Tracking the Trackers: using machine learning to aid ethical decisions

 Posted on January 16, 2020  |  Hans-Christoph Steiner

F-Droid is a free software community app store that has been working since 2010 to make all forms of tracking and advertising visible to users. It has become the trusted name for privacy in Android, and app developers who sell based on privacy make the extra effort to get their apps included in the F-Droid.org collection. These include Nextcloud, Tor Browser, TAZ.de, and Tutanota. Auditing apps for tracking is labor intensive and error prone, yet ever more in demand. [Read More]
