As of late-August 2016, WhatsApp has been sharing account data with Facebook in what the firm framed as an effort to improve targeted advertising on the social network. Although users can easily opt out of the WhatsApp → Facebook data sharing with just a few taps, most novice users are unaware that their WhatsApp usage data is being shared with Facebook.
In the United Kingdom, the Information Commissioner Office head Elizabeth Denham said her office had launched a probe into WhatsApp's updated Terms of Service a few weeks ago.
The new terms previously drew ire from European privacy watchdogs who expressed “serious concerns” over the policy change. As a result of the UK government probe, WhatsApp has now suspended account data collection and sharing with Facebook.
