California has sent out “non-compliance” to many companies who are in violation (according to the state) of the state’s privacy law.

In February 2012, The Attorney General of California announced new rules for mobile apps that strengthened the California Online Privacy Protection Act (COPPA.)  The new rules require web site and “online services” operators who collect personal information from users to conspicuously post their privacy policies.  Within that policy website operators must disclose the type of information they gather and how they use it.

The warnings from the state were sent out on Halloween, October 31, 2012.  According to Bloomberg, as reported by WebProNews,among the 100 companies that are receiving the letter include Delta and United Airlines, as well as Open Table.
