"We believe you should be able to export your information from Google products when you want to. We have a special engineering team called the Data Liberation Front which has one goal - to make it easier for our users to move their data in and out of Google products.
That's useful if you want to store a copy of your information on your own computer, or if you want to leave Google for another product and take your information to the new service. We've launched a data liberation tool called Google Takeout which makes it easier to move data in and out of Google products.
It's good to know that you can use Google Takeout to move your data in and out of Google products. "
"Google Docs can now be exported from the Google Takeout menu, thanks to Google's Data Liberation Front. Previously, users could export and import documents in various formats, but they are now available alongside data from all other Google services in Takeout.
Google Takeout was unveiled in summer 2011. It allows Google users to export all their Google data to disk or just data from individual services. It's all thanks to the Data Liberation Front team, which builds tools to give Google users control over their data."
"If you have multiple Google+ account, you can now merge those accounts via Google+ Takeout tool. Once accounts are merged, people in your circles will only see the "destination" profile."
