The precise location data of millions of users of the popular gay dating app Grindr has been for sale to the highest bidder for years, allowing purchasers to micro-target them for ad purposes, while making available possibly intimate details of their movements.
Those “precise movements,” The Wall Street Journal reports, “were collected from a digital advertising network and made available for sale,” since at least 2017. Grindr says it stopped the flow of the location data to advertising networks two years ago. Historical information may still be available.
Grindr, considered one of the first “geosocial” internet apps for LGBTQ people, was publicly released in 2009. It allows users to see other users’ profiles and sort by distance.
“The commercial availability of the personal information, which hasn’t been previously reported, illustrates the thriving market for at-times intimate details about users that can be harvested from mobile devices,” The Journal adds, noting a “U.S. Catholic official last year was outed as a Grindr user in a high-profile incident that involved analysis of similar data.”
The data for sale does not include names or phone numbers, but it is specific enough so those with access to it can “infer things like romantic encounters between specific users based on their device’s proximity to one another, as well as identify clues to people’s identities such as their workplaces and home addresses based on their patterns, habits and routines, people familiar with the data said.”
The Journal cites general concerns from national security officials “about the intelligence risks from commercially available information.” It also notes concern over the potential for blackmail.
“The U.S. government intervened to force a Chinese company into divesting itself from Grindr on national-security grounds in 2019—citing the risk of blackmail using the app data and the possibility of the Chinese government using the app’s data for surveillance purposes.”
A spokesperson for Near, the new owner of a mobile advertising company formerly named UM, told The Journal: “Every single entity in the advertising ecosystem has access to the information shared by Grindr and every other app that uses the real-time bidding system. That means thousands of entities have such access.”
In a blog post Monday, Grindr’s VP of Communications, Patrick Lenihan, calls the Journal’s report “old news,” and suggests the Journal is “[v]ictimizing LGBTQ+ people” by running “a sensationalized story.” He adds Grindr has “put privacy before profit.”
But it’s important that users know how their data was used or misused, even historically.
