California Warns Firms About Privacy for Mobile Apps

Delta Air Lines Inc., United Continental Holdings Inc. and OpenTable Inc. are among companies warned by California that they failed to comply with a consumer privacy protocol governing platforms for mobile applications, a person familiar with the matter said. Companies using as many as 100 mobile apps were told in letters sent by California Attorney General Kamala Harris that they have 30 days to conspicuously post their privacy policies for consumers of their online services, said the person.
