In section 5.7, it says that anytime you use Skype to communicate, the content is stored on Skype servers. Now, it does say that these communications can basically only be used to send to the recipient, but it goes on to say that “Skype reserves the right to review content submitted on or through the Software, Products and Skype Websites for the purpose of enforcing” terms that they specify. Some of these terms include uploading, downloading or sharing nudity, bestiality, or pornography. One other term that is quite notable is “Do not engage in activity that is false or misleading”. Now, this can be taken to mean any number of things, if argued correctly, and I think that this point is too broad. Skype reserves the right to remove access to, or cancel your account, if any of the terms are violated.
One more interesting thing I found in section 6.4 is that Skype protects you sending information to third parties, so if they take your work from a Skype message, it is still yours, and you can choose not to let them use it. The person sending, not receiving, is the intellectual owner of whatever they sent, and Skype outlines protection for them. Although, it goes on to say:
“If, at any time you choose to upload or post User Submissions to the Skype Websites or through the Software (excluding Reports and excluding the content of your communications) you automatically grant Skype a non-exclusive, worldwide, irrevocable, royalty-free, perpetual, sub-licensable and transferable license of all rights to use, edit, modify, include, incorporate, adapt, record, publicly perform, display, transmit and reproduce the User Submissions including, without limitation, all trade marks associated therewith, in connection with the Skype Websites and Skype’s Software and Products including for the purpose of promoting or redistributing part or all of the Skype Websites and/or the Software or Products, in any and all media now known or hereafter devised.”
Scratch that, you are protected from people you send information to, but if you ever send anything useful on Skype about Skype, they can take it.
