Yahoo! developed a new mobile privacy policy which highlights privacy issues specific to mobile, and is easily accessible from all of Yahoo!’s mobile services. Further, management of privacy protections should be available via any mobile device, whether that’s an iPhone or a Blackberry. Yahoo also ensures that they secure permission from users before using their GPS or cell tower. Yahoo is extending its opt-out option for interest-based ads to the users of their mobile web services. The ad-matching opt-out feature will run across Yahoo’s web services regardless of whether users have an iPhone, Blackberry or other devices.
