App makers who did not heed California Attorney General Kamala Harris’s warning that they needed to have a privacy policy accessible from the app should start looking for counsel.  Harris is now going after them under the California Online Privacy Protection Act (CalOPPA), which requires operators of commercial websites and “online services” that collect personally identifiable information to “conspicuously post” their privacy policies.  Harris has sued Delta Air Lines, Inc., alleging that the company violated CalOPPA by not providing an accessible privacy policy for its “Fly Delta” app despite her earlier warning.  The suit seeks to enjoin Delta from further violations of the Act, and also asks the court to impose a statutory penalty of $2,500 for each violation (which Harris’ office says means each time the app is downloaded).  The suit against Delta is the first such enforcement action against a mobile app operator.  Although Delta appears to have remedied the violation, the suit is still pending.
