-Deine Nutzerdetails, deine Unterhaltungen, deine Photos, deine Freunde - alles; wird sofort gelöscht und du wirst ausgeloggt.
+Die meisten Deiner Inhalte und Benutzerdaten werden kurzfristig danach durch Hintergrundprozesse gelöscht.
 
-Wenn Beiträge ablaufen, schicken wir Mitteilungen an Friendica, um diese zu löschen. 
+Parallel dazu senden wir eine Mitteilung an die Server deiner Kontakte, damit sie deine dort vorliegenden Daten ebenfalls löschen.
-Diaspora hat keine automatische Löschfunktion, so dass diese Funktion in dem Netzwerk deaktiviert ist. 
+Wir haben keinen Einfluss darauf, wie sorgfältig und ob überhaupt diese Systeme der Löschaufforderung nachgehen.
-Und hoffentlich ist klar, dass das Löschen auch in anderen Netzwerken nicht funktioniert. 
-Wenn du manuell einen Beitrag bzw. eine Reihe von Beiträgen löschst, dann senden wir individuelle Mitteilungen zu Friendica und Diaspora für jeden gelöschten Post. 
 
-Diaspora versäumt dieses oft.
+Aus technischen Gründen benötigen wir für die Übetragung dieser Mitteilung ein paar Benutzerdaten.
+Diese Daten werden dann nach einer Frist von etwa sieben Tagen ebenfalls gelöscht.
 
-Wenn du einen Beitrag löscht, aber jemand diesem Beitrag folgt, wird es trotzdem gelöscht. 
+Wir speichern deinen Benutzernamen dauerhaft, damit sich niemand einen Account unter deinem Spitznamen anlegen kann.
-Dein Wunsch hat Priorität. 
-
-Wenn du deinen Account löscht, dann löschen wir alle Beiträge, dein Profil, die Nutzerdaten etc. sofort. 
-
-Um einen Gesamtlöschauftrag zu versenden, bräuchten wir zunächst noch deinen Account; auch, um deinen Freunden zu zeigen, wer diese Anfrage stellt. 
-Das können wir nicht tun, wenn du keinen Account mehr hast. 
-
-Deine Freunde können möglicherweise noch deine Beiträge sehen, wenn dein Account gelöscht wurde, aber es gibt keinen öffentlichen Ort in Friendica mehr, wo diese angeschaut werden können. 
-Wenn du Freunde bei Diaspora hast, kann es sein, dass deine Beiträge weiterhin vorhanden und für andere aus diesem Netzwerk sichtbar sind.
