SHREDroid Android data wiper
SHREDroid can erase Android internal memory as well as external SD cards, it can be configured to run in the background while your phone is locked and you can schedule the app to automatically run at intervals, before you set it up to wipe your smartphone memory card every day, remember that flash memory has a limited number of overwrites, this app is very handy to sanitize your Android phone once in a while but I wouldn’t use it daily.
