An anonymous reader quotes a report from BuzzFeed: The gay hookup app Grindr, which has more than 3.6 million daily active users across the world, has been providing its users' Hiv Status to two other companies, BuzzFeed News has learned. The two companies -- Apptimize and Localytics, which help optimize apps -- receive some of the information that Grindr users choose to include in their profiles, including their HIV status and "last tested date." Because the HIV information is sent together with users' GPS data, phone ID, and email, it could identify specific users and their HIV status, according to Antoine Pultier, a researcher at the Norwegian nonprofit SINTEF, which first identified the issue. Grindr was founded in 2009 and has been increasingly branding itself as the go-to app for healthy hookups and gay cultural content. In December, the company launched an online magazine dedicated to cultural issues in the queer community. The app offers free ads for HIV-testing sites, and last week, it debuted an optional feature that would remind users to get tested for HIV every three to six months. But the new analysis, confirmed by cybersecurity experts who analyzed SINTEF's data and independently verified by BuzzFeed News, calls into question how seriously the company takes its users' privacy. SINTEF's analysis also showed that Grindr was sharing its users' precise GPS position, "tribe" (meaning what gay subculture they identify with), sexuality, relationship status, ethnicity, and phone ID to other third-party advertising companies. And this information, unlike the HIV data, was sometimes shared via "plain text," which can be easily hacked.
