Seems sketchy... how are they offering their services for free? What's the gotchas?
"In order for us to provide you with our file transfer service we require you to grant us licences in respect of the files you wish to transfer. Specifically, when you upload a file to our site, you grant us a perpetual, worldwide, nonexclusive, royalty-free, transferable licence to use, reproduce, distribute, and perform that file to enable us to transfer and store your file; and the right to sublicense this right to third parties. We claim no ownership or knowledge of content of your files as we only require what is necessary to facilitate your file transfer."
Sounds sketchy to me
So, the "sublicense this right to third parties" I think is because we are storing the files on S3. I see, this phrase doesn't look good .. do you think it would be better to explain sublicense to amazon for the storage, or even better get rid of this ?
About the "perpetual", if would be "10 days" , which is the expiration time for every transfer, would it better?
Cheers
Now of course these are only words and the only way to be sure is to encrypt your files.
