Full disclosure required for app users in California

If you’ve developed a mobile app, there’s a good chance that you’ve got at least one user that’s from Silicon Valley or California, which might not seem like a big deal. But if you’re also collecting user data, it can be a big deal because of an existing, but little known state law, called the California Online Privacy Protection Act.  According to this law, if a mobile app collects any personal data from a California resident, the app must provide a security policy for users.
