File wiping. What I mean is that feature where the file can be deleted unrecoverabely. I've seen this only in a few apps so it's super duper rare on Android. And those apps aren't even getting updates anymore so most of em don't support android 11. I've seen this wiping feature a.k.a "Shredding" on pc applications and pretty sure at least one of Ashampoo's apps have this feature so you definitely don't need further explanation.
