“Grindr also sent a user's location to multiple companies, which may then share that data with many other businesses, the report said. When the New York Times tested Grindr's Android app, it shared precise latitude and longitude information with five companies.”
“Grindr's app, for instance, includes software from MoPub, Twitter's ad service, which can collect the app's name and a user's precise device location, the report said. MoPub in turn says it may share user data with more than 180 partner companies.”
