Well it's google so expect them to log everything.

now google has even more information on you. It can see who calls you for what time, who you are calling, logging your sms en voicemail, together with logging of your gmail en logging your searches they can make a nice profile of you.

Profiles are worth a lot and is nice for marketing.

Stay away fro google if you want privacy and I wouldn't even use them for your business giving away information to them.
