## 9.12\. Data Deletion
All device implementations:
* [C-0-1] MUST provide users a mechanism to perform a "Factory Data Reset".
* [C-0-2] MUST delete all data on the userdata filesystem.
* [C-0-3] MUST delete the data in such a way that will satisfy relevant
industry standards such as NIST SP800-88\.
* [C-0-4] MUST trigger the above "Factory Data Reset" process when the
[`DevicePolicyManager.wipeData()`](
https://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#wipeData%28int%29)
API is called by the primary user's Device Policy Controller app.
* MAY provide a fast data wipe option that conducts only a logical data erase.
