+This chatmail server neither asks for nor retains personal information. 
+Chatmail servers exist to reliably transmit (store and deliver) end-to-end encrypted messages
+to one or more devices. 
+A Chatmail server is more similar to how the Signal messenger server relays messages
+than to classic e-mail servers who maintain permanent storage with readable personal data. 
+In particular,

+- this chatmail server unconditionally removes any messages after {{ config.delete_mails_after }} days. 
+- Log files are ephemeral and only analyzed for debugging purposes

+Technically, you may think of Chatmail servers as a "messaging router" at Internet-scale. 
+Legally, authorities might regard this chatmail server as a "classic e-mail" server
+which collects and tracks personal data, requiring an according privacy policy. 
+We do not agree on this interpretation. Yet, we provide more legal details below
+to make life easier for data protection specialists and lawyers.
