Making good on her promise, California Attorney General Kamala Harris has continued her crackdown on mobile-app developers and companies for not doing more to ensure users' privacy. She announced today that she'll be sending letters to 100 app developers and companies to formally notify them that they're violating California's privacy laws.

"Protecting the privacy of online consumers is a serious law enforcement matter," Harris said in a statement today. "We have worked hard to ensure that app developers are aware of their legal obligations to respect the privacy of Californians, but it is critical that we take all necessary steps to enforce California's privacy laws."
