Privacy Policy Jabber / XMPP service takes the protection of personal information very seriously and strictly adheres to the rules of data protection laws. Personal data is collected on this server only to the extent technically necessary. In no case will the collected personal data be sold or passed on to third parties for other reasons, unless we are legally obliged to disclose the data.


Which data is stored?

In principle, the server stores the following data:

  • The Jabber ID (JID)   consisting of username and domain to identify the user account.
  • The password for the Jabber account for identification when logging in the Jabber client to the server (stored encrypted!).
  • The user's Contacts stored in the lineup along with the information about which direction (s) the visibility exists with that contact. This is saved so that you can log in from different clients and always have the same contacts.
  • Date and time when the user account was created and when it was last used. This is done so that unused user accounts can be automatically deleted.
  • While the user is not logged in, incoming messages addressed to him are cached so they can be delivered to him the next time he logs on. These messages also record when they arrived.
  • In the case of server problems / troubleshooting we can view IP addresses, but these are neither forwarded to users nor evaluated.
  • In case of delivery errors a message is saved by whom the message went to and why the delivery did not work. But not the content of the message. This is necessary in order to be able to determine a problem with accumulated errors.
  • If your client uses XEP-0363: HTTP File Upload , uploads to the server will be delayed for max. 10 days deleted. Please note that some clients only store this data unencrypted on the server!
  • If XEP-0313 MAM Through the user, the server stores message content for 1 month. The entertainment recordings are then automatically deleted. By default, MAM is not active and must be explicitly enabled by the user or the XMPP client being used!

When using gateways / transports, these transitions store more data:

  • Network transitions to other IM systems store the username and the password for the foreign IM system.
  • Network transitions to other IM systems write a log when which Jabber ID was used to establish which user identity in a foreign IM system

It is also possible for the Jabber client to save data to the server. This data can either be stored by the Jabber client so that it can be queried by other Jabber users (e.g., vCards containing contact information) or so that only the user of the account can retrieve the data (e.g. Configuration settings of a Jabber client). What data, to what extent and for how long are stored so is the Jabber client.

Of all the above data, backups (backup copies) are made regularly and kept for a few days. In this backup, actually deleted data may persist for a few more days.

What happens to this data?

The data stored about a user will not be used commercially. They will not be sold or shared with third parties. No advertising is sent to the users of this service, not even in their own right.
The following exceptions exist: If the user's data are saved by this or his user program to be published (this includes in particular a stored vCard), this information can be retrieved individually by other users The operator of this server expressly prohibits the use of this service to send unsolicited (ie not explicitly requested) advertisements, but can not enforce them in all cases.

Messages sent from one user to another can be delivered to other servers. The treatment there is not necessarily subject to the assurances for this server. The same applies to information that the user has designated for the distribution to other users or all users (for example, information about the online status / presence to users whom he has given permission for, as well as for technical reasons, the servers of these Users are used).

If the user uses transitions to other IM systems, the protection of his privacy and data also depends on the circumstances of the other system. In particular, some systems allow users to view their online state / presence without the user's explicit consent.

Users' IP addresses are not shared by this server with other users. All communication via the Jabber protocol takes place via the server. However, Jabber clients can send each other their IP address within messages to eg. B. to start a file transfer. However, the server does not check this IP address and does not forward a user's IP address to a third party.

From the collected data statistics about usage and usage of the server are obtained. These statistics are created anonymously; a conclusion on individuals is not possible from these statistics.

Ambiguities and further questions can be discussed with the administrator of the server (see Imprint) This server is subject to the laws and privacy policies of the Federal Republic of Germany and the European Union.
