Google has access to WiFi passwords stored in Android mobile devices http://securityaffairs.co/wordpress/17841/laws-and-regulations/goolge-ac…
Accepting defaults on your android phone – or accepting offers to link to your gmail account contact lists to ‘share' with your contacts your latest purchases, games you liked, or LinkedIn or Twitter comments – is a huge privacy risk. And, in my opinion, far too easy to accept a pop-up window without realizing that you just granted permission for the program to access all your contacts. (See my earlier post, Is Your Email Secure.)
Do you really need to use Gmail or other free email service providers for your business email service? If this causes a privacy breach, how ‘free' is the service?
