Popular dating services like Grindr, OkCupid and Tinder are spreading user information like dating choices and precise location to advertising and marketing companies in ways that may violate privacy laws, according to a new report that examined some of the world’s most downloaded Android apps.
Grindr, the world’s most popular gay dating app, transmitted user-tracking codes and the app’s name to more than a dozen companies, essentially tagging individuals with their sexual orientation, according to the report, which was released Tuesday by the Norwegian Consumer Council, a government-funded nonprofit organization in Oslo.
Grindr also sent a user’s location to multiple companies, which may then share that data with many other businesses. It shared precise latitude and longitude information with five companies.
The researchers also reported that the OkCupid app sent a user’s ethnicity and answers to personal profile questions — like “Have you used psychedelic drugs?” — to a firm that helps companies tailor marketing messages to users. The Times found that the OkCupid site had recently posted a list of more than 300 advertising and analytics “partners” with which it may share users’ information.
“Any consumer with an average number of apps on their phone — anywhere between 40 and 80 apps — will have their data shared with hundreds or perhaps thousands of actors online,” said Finn Myrstad, the digital policy director for the Norwegian Consumer Council, who oversaw the report.
