But there is a small catch. Here’s what the terms say:
Dropbox — terms can be found here:
“Your Stuff & Your Privacy: By using our Services you provide us with information, files, and folders that you submit to Dropbox (together, “your stuff”). You retain full ownership to your stuff. We don’t claim any ownership to any of it. These Terms do not grant us any rights to your stuff or intellectual property except for the limited rights that are needed to run the Services, as explained below.”
Microsoft’s SkyDrive — terms can be found here:
“5. Your Content: Except for material that we license to you, we don’t claim ownership of the content you provide on the service. Your content remains your content. We also don’t control, verify, or endorse the content that you and others make available on the service.”
Google Drive — terms can be found here:
“Your Content in our Services: When you upload or otherwise submit content to our Services, you give Google (and those we work with) a worldwide licence to use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations or other changes that we make so that your content works better with our Services), communicate, publish, publicly perform, publicly display and distribute such content.
The rights that you grant in this licence are for the limited purpose of operating, promoting and improving our Services, and to develop new ones. This licence continues even if you stop using our Services (for example, for a business listing that you have added to Google Maps).”
The last sentence makes all the difference. While these rights are limited to essentially making Google Drive better and to develop new services run by Google, the scope is not defined and could extend far further than one would expect.
The answer is Google. You decide, which drive to use?
