Our basic approach to data protection is to store only what is necessary for the operation of our service. In this document we explain which personal data is processed and for what purposes.
Which data we store
Your user name and a cryptographic hash of your password
Your email address, if you choose to provide one. This is used exclusively
for account-related functions such as password recovery.
The date your account was created.
Offline messages: If someone sends you a message while you are not connected,
the message is cached until you are next online so it can be delivered.
Message archive: By default, we maintain an archive of your messages so that
you can access your chat history later, for example when logging in from a new device.
this is also necessary if you want to use OMEMO encryption on multiple devices.
You can disable server-side archiving at any time via the corresponding settings
in your XMPP client.
Every file that you share with individual contacts or in conferences is uploaded to our servers and
stored so that the recipients can access or download it later.
Your contact list (Roster/Buddylist), which you manage yourself.
You decide which contacts are added or removed.
Information you publish for your contacts, for example your avatar or
your public OMEMO keys.Additional private data that your XMPP client may upload,
such as a list of conference bookmarks.
The operation of this service is financed through myself and through donations.
This means we do not need to analyse or sell your data and we will not do so
in the future.Our servers are located in Nürnberg, Germany, and are hosted by NetCup.
If you delete your account, all associated data will be removed as well,
including your files and messages.
