On Tuesday, software giant Microsoft whacked Internet search biggie Google with `Scroogled' - Microsoft's attack ad-based campaign aimed at Google - for the third time; with the key focus of the third wave of `Scroogled' largely being the supposed privacy flaws in Google's official Android app store, Google Play.

The launch of the third wave of `Scroogled' by Microsoft comes after `Scroogled' first bashed Google over its search practices last year; and then in February this year, followed with an attack on Gmail for machine-reading messages to embed targeted ads in the users' browsers.

In a Tuesday assertion on its revamped Scrooggled. com site, Microsoft said that the privacy flaws in Google Play are evident from the fact that any purchase of Android app from the Google store requires the customers to give the app maker their full name, email address, as well as information about the neighborhood where their live.

Noting that the above-mentioned details are sought from the customers "without clear warning" every time they purchase an app from Google Play, Microsoft said on the website: "If you can't trust Google's app store, how can you trust them for anything?"

Contrasting the portrayal of the Google Play store with the practices of its own app market, the Windows Phone Store, Microsoft said: "Windows Phone Store does not share any personally identifiable information with the app maker."
