Back in December 2018, UK advocacy group Privacy International (PI) published a study which outlined Android apps which share sensitive personal data with Facebook, even if a user did not have a Facebook account.
You may know that Facebook tracks its users, but did you know it also tracks non-users and logged-out users outside its platform through Facebook Business Tools? App developers share data with Facebook through the Facebook Software Development Kit (SDK), a set of software development tools that help developers build apps for a specific operating system.
In PI’s study, they analysed the data of 34 Android apps, each selected because of their install base from 10 to 500 million which were transmitting data to Facebook through the Facebook SDK.
Of the free apps tested from the Google Play Store, 61% tested automatically transfer data to Facebook the moment a user opens the app. This happens whether people have a Facebook account or not, or whether they are logged into Facebook or not.
What is surprising is that many of these are popular apps which you probably are currently using such as Spotify, Trip Advisor, Shazam, and Skyscanner,
As of March 2019, PI had retested all the apps from the previous report. Thankfully, their report seems to have made an impact as two thirds of the apps it retested, including Spotify, Skyscanner, and KAYAK were found to have their apps so that they no longer contact Facebook when you open the app.
However, there were still many apps which exhibited the same behaviour from the original report, whereby they were transferring data to Facebook before users are able to agree or consent.
Among those are:

PI also recommends these tips to reduce app tracking on your Androids, (although they do not prevent the type of tracking described in their report):
