How you leave your devices sparkling clean.

Erase your data easily – that’s how it works

On iOS-Devices (Version 12.1)

Einstellungen (Settings) – Allgemein (General) – Zurücksetzen (Reset) – Alle Inhalte & Einstellungen löschen (Delete all content & settings)

Note: The factory settings of your Apple devices encrypt your personal data. Your personal data is therefore no longer readable if you reset your smartphone. 

On Android-Devices (Version 8.1.0)

Einstellungen (Settings) – System – Zurücksetzen (Reset) – Auf Werkseinstellungen zurücksetzen (Reset to factory settings)

Note: According to information from the manufacturer, all data is automatically encrypted from version 6.0 of the Android software onwards. Your personal data is therefore no longer readable if you reset your smartphone. If you own a phone with an older version of Android, before you reset it please check whether the encryption function can be activated under Einstellungen (Settings) – Sicherheit (Security).
