On December 9, 2020, the Wall Street Journal reported that Apple and Google will block the data broker X-Mode Social Inc. (“X-Mode”) from collecting location data from iPhone and Android users. Apple and Google have reportedly informed app developers to remove the X-Mode social tracking SDK from all of their apps within a short period of time or risk removal from the platforms’ app stores.  This action apparently was prompted by reports that X-Mode was selling location data to certain defense contractors and government entities.

The WSJ report suggests that Apple and Google notified Senator Ron Wyden about this action.  Senator Wyden and a group of other Senators have been soliciting government inquiries over the last several months into the sale of location data to government contractors and agencies. It is Senator Wyden’s position that such sales of users’ location data by commercial data brokers to government entities are unlawful without a warrant (citing the Supreme Court case, Carpenter v. United States, 138 S.Ct. 2206 (2018), which held that the acquisition of cell-site location information was a Fourth Amendment search).

Senator Wyden’s scrutiny over such practices does not seem to be limited to sale of location data to government sources, but more so toward the wider data tracking ecosystem. He was one of the senators that earlier this year sent a letter to FTC Chairman Joseph J. Simons urging the agency to investigate whether analytics firm Yodlee’s financial data collection practices were violating the FTC Act (a request which led to at least one civil investigative demand being issued by the FTC to Yodlee and a putative class action suit over such practices). In the WSJ article, Wyden is quoted as stating: “Apple and Google deserve credit for doing the right thing and exiling X-Mode Social, the most high-profile tracking company, from their app stores. But there’s still far more work to be done to protect Americans’ privacy, including rooting out the many other data brokers that are siphoning data from Americans’ phones.”
