What “Privacy & Security” should be

Incredibly eye opening. I highly suggest this app to those whom are seeking the nitty-gritty that Settings’ “Privacy & Security” simply doesn’t provide.

Of all three API categories, “Passive” bewildered me the most, surprisingly. I’m no programmer, although I’ve known about iOS API’s since forever. I had no idea they returned so much information. Battery status; audio volume; display; and device motion, just to name a few, were the most telling for what would seem insignificant by themselves.
