This page attempts to describe what personal information servers stores about you. If you have any questions, please don't hesitate to contact us.


The XMPP Server stores the following data:

Additionally, a Jabber client may store data on the server. If that data is accessible to others (like a vCard which contains contact details) or accessible only to you (like configuration settings for a Jabber client) lies in the hand of the client you use.


All emails you send and receive while using our email platform, as well as all contacts, are stored on an encrypted file system.

The email system stores the following data:

What happens to that data?

The information about our users are neither being used commercially nor sold or otherwise made available to third parties. No advertisements are being sent to the users of this service.

There exist a few exceptions to that rule: When a user stores data specifically to make it available to others (think of, for example, a stored vCard), it can be retrieved by other users.

The Jabber IDs (JID) or the email address of users will not be published; if a user, however, publishes his/her ID, third parties could use that information to send advertisements to that user. This is not unlikely to occur with the receival of a common mail message through the e-mail transport. The provider of this service specifically forbids using it to send unsolicited (that is, not explicitly requested) ads. However, the provider can not guarantee all users' compliance to this rule.

Messages sent from a user to another one connected to a different server can be sent to the latter entity. How data is being treated at the receiving end can differ from what is described in this document. The same holds true for information the user has selected for display to other users or all users (e.g. information about the online status/the presence).

The Jabber server does not report the IP addresses of users to other users. All communication using the Jabber protocol (XMPP) takes place with the server as a middleman. Clients can, however, exchange IP addresses, for instance before starting a file transfer. The server will neither examine those addresses nor forward them to third parties.

Statistics about the server's load will be derived from collected data. These statistics are anonymous. No information about single persons can be obtained from them.


The Servers are backuped daily to an encrypted remote location. The data is encrypted before it is send over the wire. The backups are stored for 7 days.
