[APP][4.0.3+] Data Sanitizer - Simple App to Wipe Data Remanence

Data Sanitizer is simple data remanence wiping tool, it ensures that no data can be recovered.
Started as a fun project when I wanted to sell my phone, then I decided to slap some UI on it and publish it on Google Play :D

The app is pretty simple and straight forward, it detects how much free storage you have and then wipes any traces of data in it so nothing can be recovered. The app implements the GOST R 50739-95 data wiping method.

Any reviews/suggestions are appreciated :)

i cant wipe my mobile data heeeeelllp

Hey guys I'm running dn4 v2 on my mobile galaxy note 2, and whenever I wipe data in clockworkmod recovery it powers off and reboots.... everything else works, flashing ROMs, wiping cache and dalvik cache, but wiping data restarts the phone back into recovery. I ttried flashing TWRP but that recovery results in a boot loop, in which I had to flash CWM again from Odin..... I really do not know how to fix this, the ROM I'm running works so bad , and I really can't flash other roms without being able to wipe data......
