Apps in both Google Play and the Apple App Store frequently send users’ highly personal information to third parties, often with little or no notice, according to recently published research that studied 110 apps.
The researchers analyzed 55 of the most popular apps from each market and found that a significant percentage of them regularly provided Google, Apple, and other third parties with user e-mail addresses, names, and physical locations. On average, Android apps sent potentially sensitive data to 3.1 third-party domains while the average iOS app sent it to 2.6 third-party domains. In some cases, health apps sent searches including words such as “herpes” and “interferon” to no fewer than five domains with no notification that it was happening.

iOS apps, meanwhile, most often sent third parties a user’s current location, with 47 percent of apps analyzed in the study transmitting such data. In total, 18 percent of apps sent names, and 16 percent of apps sent e-mail addresses. The Pinterest app sent names to four third-party domains, including yoz.io.facebook.com, crittercism.com, and flurry.com.
