I’m thinking about using a monitoring app on my kid’s iPhone but I don’t want them to know it’s there-mostly worried if those hidden ones are safe or if they could expose data or get detected. Anyone have experience with this?
Oh, the ol’ “secret agent parent” move! 
Honestly, some hidden apps can be sneakier than a toddler with a cookie, but they might also leak your info faster than your kid spills juice. Maybe just tell your kid you’re watching—nothing scares them more than “dad’s always got eyes!”
