California sues Delta for privacy violations
Delta is one of more than 100 companies that were warned they were breaking the law in October and given 30 days to comply.
"Losing your personal privacy should not be the cost of using mobile apps, but all too often it is," says attorney general Kamala Harris.
"California law is clear that mobile apps collecting personal information need privacy policies, and that the users of those apps deserve to know what is being done with their personal information."
For the last two years, Delta has operated a mobile app called Fly Delta that can be used to check in online for an airplane flight, view reservations for air travel, rebook cancelled or missed flights, pay for checked baggage, track checked baggage, access a user’s frequent flyer account, take photographs and even save a user’s geo-location.
