On average, 88% of the top Android apps connects to third-party services, and 41% send data to Facebook’s Audience platform. The data comes from AdGuard, which assessed 2556 of the top Android apps, and ultimately found 61% sent some form of identifying data out.
Facebook’s Audience Network was the most popular third-party service for collecting data, followed by Google. However, on phones without a Facebook app installed, the least amount of data was collected.
Google also owns the three tracking services that sit just behind Facebook in the chart. Crashlytics comes second with 39.5% using the service, followed by DoubleClick with 31.6%, and Google Analytics with 12.6%. Yahoo’s Flurry comes fifth with 11.5%.
