Google Inc's privacy practices are drawing heat after an Australian software developer said the company was providing him with personal information, including email addresses, of everyone who purchased his mobile app.
The information that Google shared, which included customers' full names, email and some postal code information, was not the result of a glitch with its software.
Rather it appears to be in accordance with Google's existing policies for its app store and its Google Wallet payment service - though some privacy advocates believe Google has not been clear enough in informing consumers about the practice.
Google has "buried" the notice about how it shares users' personal information in fine print rather than obtain the express consent of users, said Marc Rotenberg, executive director of the ElectronicPrivacyInformationCenter.
"Meaningful consent is about people understanding what they're getting into. It's about not tricking them," said Rotenberg. "In a situation like this, where people just don't know what information is being transferred or who it's going to or for what purpose, it seems ridiculous to say that Google has consent."
The episode represents the latest privacy flare-up for Google, the world's No.1 search engine. In August, Google agreed to pay a $22.5 million fine to settle charges that it bypassed the privacy settings of customers using Apple Inc's Safari browser.
Google also settled a privacy investigation by the Federal Trade Commission 2011 related to its rollout of the now-defunct Buzz social networking service.
Other Web companies, including Facebook Inc, have also drawn scrutiny over their privacy practices and entered into settlements with regulators.

EPIC's Rotenberg said he believed that Google may be violating its 2011 settlement with the FTC.
Developer Dan Nolan broke the issue online in a blog post on Tuesday: "This is a massive oversight by Google. Under no circumstances should I be able to get the information of the people who are buying my apps unless
