California law requires mobile apps that collect personal information to disclose prominently what they do with it. Delta Airlines doesn't, so the state sued after a 30-day warning.
We noted in an edition of the Friday Four early last month that Harris had sent warning letters to Delta and to a reported 100 other mobile app makers. Now, a month later, the lawsuit against Delta may be the first of in a series.
That pesky law
Following a string of privacy fiascos involving mobile apps beginning last year (anyone remember Path?), Harris decided to stretch the 2004 law to encompass mobile apps as well as websites. She brokered a deal last February with a half dozen major mobile app platform vendors -- Amazon, Apple, Google, HP, Microsoft, and Research In Motion -- in which they agreed to require privacy policies for all apps they host.
Fences are going up across what had once been the Wild West. Joe Mullin, writing in Ars Technica, put it well when he wrote, "The days when most mobile apps have been able to just blow off the requirement are likely coming to a close."
