Winter is as good a time as any other for some spring cleaning when it comes to data privacy. In this case, the task is dusting off the privacy policies that you probably had drafted a while ago and probably have not looked at since to make sure they are up to date with any changes in the law.  One change that took place early this year is California’s requirement that a company disclose how it responds when a visitor’s Web browser sends a “Do Not Track” signal.  If you have not made this change to your privacy policy, now is the time to get compliant.
