Well, I've never been one to take
T&Cs seriously, but this seems a little odd:
1.4
Third Party Services. The Service may allow you to give third party websites, apps, and services (“Third Party Services”) access to Your Files, including the ability to make copies of Your Files, modify or delete Your Files, or create new files on your behalf. The use and storage of Your Files by Third Party Services will be governed by their privacy policies and terms. Amazon has no responsibility or liability with respect to your use of Third Party Services or the content, functionality, or acts of Third Party Services you use.
3.3
Our Use of Your Files to Provide the Service. We may use, access, and retain Your Files in order to provide the Service to you and enforce the terms of the Agreement, and you give us all permissions we need to do so. These permissions include, for example, the rights to copy Your Files for backup purposes, modify Your Files to enable access in different formats, use information about Your Files to organize them on your behalf, and access Your Files to provide technical support. Amazon respects your privacy and Your Files are subject to the Amazon.com Privacy Notice located at
www.amazon.com/privacy.
I mean, I'm not sure if all cloud services have this sort of thing written in the fineprint, (I've got Dropbox 1TB, knowing my luck, it's the same) but those ones I've quoted do ring some alarm bells
EDIT:
Okay so Dropbox's is:
Others working for Dropbox. Dropbox uses certain trusted third parties to help us provide, improve, protect, and promote our Services. These third parties will access your information only to perform tasks on our behalf and in compliance with this Privacy Policy.
Other users. Our Services display information like your name and email address to other users in places like your user profile and sharing notifications. Certain features let you make additional information available to other users.
I guess that's a little better, well ... certainly inspires more confidence than Amazon's.
