+    * Does not have its own backend server. Instead Delta Chat relies on using the existing email standards. It is on the list due to being a solid messenger, and the fact that it is fairly simple to self host an email server just for use with this app. Which just barely qualifies it as self hosted. 
+
+  * Description:
+Delta Chat is like Telegram or Whatsapp but without the tracking or central control. Check out our GDPR compliancy statement. Delta Chat doesn’t have their own servers but uses the most massive and diverse open messaging system ever: the existing e-mail server network. Chat with anyone if you know their e-mail address, no need for them to install DeltaChat! All you need is a standard e-mail account.
