A Norwegian nonprofit has discovered that the information is being shared with two private companies that help “optimise” apps, Localytics and Apptimize. These companies are also aware of the users’ screen names, GPS locations, e-mails and phone IDs. The company also shares users’ sexual orientation, relationship status, “tribe,” and ethnicity with the companies if the information is listed in their profile. It is the latest Grindr security flaw to be exposed in the past month after it was revealed location data is being shared, even when users opt out. The security flaws were discovered by Trevor Faden after he created C*ckblocked, a website that enabled Grindr users to find out who had blocked them. “Thousands of companies use these highly-regarded platforms. These are standard practices in the mobile app ecosystem,” Grindr Chief Technology Officer Scott Chen told BuzzFeed, who confirmed the information, “The limited information shared with these platforms is done under strict contractual terms,” he added, insisting that the level of confidentiality allows to make a conclusion that the users’ data is kept safe and their privacy is not violated.
