Data Privacy Statement from mailbox.org:
"According to TKG Section 113 (German Telecommunications Law), the public prosecutor and the police can access the user data held by telecommunications providers such as ourselves relatively easily. A simple information request suffices; no court order is needed. According to TKG Section 113, a telecommunications provider has no legal recourse against such a request; it must comply. It should also be noted that according to TKG Section 113 (II), the provider is required to treat such a request confidentially, and that the affected customer must not be informed about the request."
