California has sued Delta Airlines for violating the state\'s Online Privacy Protection Act by not warning consumers sensitive information is being collected. In the first legal test of an 8-year-old law, California says the airline is violating the statute that requires companies to prominently notify app users about what information is being collected and how it will be used, KABC-TV, Los Angeles, reported Friday. Attorney General Kamala Harris filed the suit in San Francisco Superior Court, alleging Delta does not warn consumers sensitive information is collected from users of the company\'s \"Fly Delta\" mobile application that allows customers to check in for a flight, review reservations, book flights and pay for checked baggage. Harris said she is seeking an injunction prohibiting Delta from distributing the application until it posts a privacy policy in compliance with the state law. California is the only U.S. state with an apps-privacy law. Delta had no comment on the pending litigation, KABC-TV said.
