Just a few interesting bits:
What is Google doing?: In a nutshell, Google is taking information from almost all of your Google services — including Gmail, Picasa, YouTube and search — and integrating the data so that they can learn more about you. (Information from Google Books, Google Wallet and Google Chrome will not be integrated, partly for legal reasons.)
What kind of information are they collecting and integrating?: Almost anything that’s already in the Google ecosystem: calendar appointments, location data, search preferences, contacts, personal habits based on Gmail chatter, device information and search queries, to name a few.
Can they do that?: Not under the company’s current privacy policies, but Google is introducing a new, unified policy that you can’t opt-out of.
When do the changes take effect?: March 1.
Can I opt-out?: No.
So what do I do if I don’t like the policy?: You can close your account. Google has provided information on how to take all of your personal information off of Google by closing your Google Account, which would erase your Gmail, Google+ and other accounts.
But I have a lot of data saved on Gmail/Picasa/etc…: Google says it is committed to “data liberation” and that it will allow you to take your information elsewhere if you want to. The company said it would provide directions on how to do this in the help sections for its various services.
I’m thinking about deleting a few things.
