I'm wondering about the legal implications of this. While IANAL, SMS are (at least in Germany) also covered by the right to privacy of correspondence. Uploading them to your servers would violate that as long as you don't have the explicit permission by the other recipient. (+ you seem to be reading/accessing the contents?!)

This is something that we take seriously. We use SSL and data encryption for the storage, and everyone can delete his data in one click at any time. We do read the content of the texts. The printing part is automated and externalized. (it is like printing photos).

However, your are right we do not have the explicit permission of the other recipient. It's kind of tricky to ask for this permission. Any thoughts?
