In 'Egregious Breach' of Privacy, Popular App Grindr Supplies Third Parties with Users' HIV Status

Just after civil liberties groups unveiled a new "Security Pledge," urging tech companies to do more to protect users' personal information, reports surfaced on Monday that the popular app Grindr has been supplying companies with data on its users' HIV status.

BuzzFeed reported on the findings of a Norwegian nonprofit research organization, SINTEF, which showed that the dating and social networking app has supplied two companies that claim to "optimize" applications with users' HIV status, most recent HIV test dates, location, phone, and email information.

Much of the information is sent to the companies, Apptimize and Localytics, in plain text, which experts say leaves it vulnerable to hacking.

"When you combine this with an app like Grindr that is primarily aimed at people who may be at risk--especially depending on the country they live in or depending on how homophobic the local populace is--this is an especially bad practice that can put their user safety at risk," Cooper Quintin, senior staff technologist and security researcher at the Electronic Frontier Foundation, told BuzzFeed News.

Journalist Steven Thrasher wrote on Twitter that the revelation of Grindr's privacy violation could have wide-reaching effects on the app's 3.6 million users.

Critics scoffed at an explanation released by Grindr, which stated, "Thousands of companies use these highly-regarded platforms. These are standard practices in the mobile app ecosystem."

"Even if Grindr has a good contract with the third parties saying they can't do anything with that info, that's still another place that that highly sensitive health information is located," Quintin said. "If somebody with malicious intent wanted to get that information, now instead of there being one place for that--which is Grindr--there are three places for that information to potentially become public."

Grindr's actions could cost the company its reputation as a promoter of safe sex and open dialogue about health status between sexual partners.

"Grindr is a relatively unique place for openness about HIV status," James Krellenstein, a member of the AIDS advocacy group ACT UP New York, told BuzzFeed News. "To then have that data shared with third parties that you weren't explicitly notified about, and having that possibly threaten your health or safety--that is an extremely, extremely egregious breach of basic standards that we wouldn't expect from a company that likes to brand itself as a supporter of the queer community."
