In the first place, why would this app even need to include their names and pictures? That’s begging for bad things to happen.

Let their parents assign some nickname or code name to the tags. The parents will know what that is. As opposed to some weirdo who steals your phone or some hacker who sells a db dump to pedophiles on the dark web.

C is kind of a bad example though, as Java should mostly be platform independent.

But then that’s not really “native”.
