+                            This service is provided on a pro bono basis. An email
+                            address is not needed to sign up and we don't sell or

+                        <p>
+                            We don't share any of your data with 3rd parties,
+                            except when necessary to run the service. For example,
+                            when you send a message to a user on a differerent XMPP
+                            server.
+                            Your presence information (whether you're online or
+                            not) is shared with contacts that you've added from
+                            other servers.

+                            can request access to your (optionally filled-in) VCard data.
+                            You can remove your VCard data through an XMPP client.
+                            The latest version of Converse supports this, and you can

+                        <p>
+                            Our XMPP server runs in a Hetzner data centre in
+                            Strasbourg, France.
+                        </p>
+                        <p>
+                            Your chat messages are archived for a period of 1
+                            month, after which they are deleted.
+                        </p>
+                        <p>
+                            Currently the <strong>conversejs.org</strong> XMPP
+                            server does not support HTTP-file upload, which means
+                            that we don't host any uploaded files of users.
+                        </p>
+                        <p>
+                            During normal operations we don't log or process IP
+                            addresses, although it might be necessary in certain
+                            cases where a problem needs to be debugged (hasn't
+                            happened yet). Logs older than 6 months are deleted.
+                        </p>
+                        <h4>Data portability</h4>
+                        <p>
+                            Currently there is no standardized way to move a
+                            user account from one XMPP server to another.
+                        </p>
+                        <p>

+                        <p>
+                            Currently it's not possible to automatically delete
+                            your account via Converse, although you might be
+                            able to do so via other XMPP clients that support
