Did App Privacy Improve After the GDPR?

• In this article, we present an analysis of app behavior before and after the regulatory change in dataprotection in Europe. Our data shows that app privacy has moderately improved after the implementationof the General Data Protection Regulation.In May 2018, stronger regulation of the processingof personal data became law in the EuropeanUnion, known as the General Data Protection Regulation(GDPR).1 The expected effect of the regulation was betterprotection of personal data, increased transparencyof collection and processing, and stronger interventionrights of data subjects, with some authors claiming thatthe GDPR would change the world, or at least that ofdata protection regulation.2 The GDPR had a two-year(2016–2018) implementation period that followedfour years of preparation. At the time of this writing,in November 2019, one and one-half years have passedsince the implementation of GDPR.Has the GDPR had an effect on consumer software?Has the world of code changed too? Did theGDPR have a measurable effect on mobile apps’behavior? How should such a change in behavior bemeasured?In our study, we decided to use two indicators for measurement:Android dangerous permission16 privileges anduser feedback from the Google Play app market. We collecteddata from smartphones with an installed app set formonths before GDPR implementation on 25 May 2018and months after that date.
