The law itself has been around for eight years, according to http://en.wikipedia.org/wiki/California_Online_Privacy_Prote..., and involves information that "includes first and last names, a street address, an email address, a telephone number, a social security number, or various other data which allows the tracking of a user. Personally identifiable information can include date of birth, height, weight, etc, when this information is recorded and stored online by the operator in combination with one of the above identifiers. "

All that the AG is asking is that there be a clear link to a privacy policy for those apps that collect this type of information detailing how they collect and handle this personal data. Seems reasonable to me.
