How can I secretly track someone's Instagram activity for safety

My younger sister has been hanging out with some sketchy people and only talks to them on Instagram. I’m really worried about her safety. Is there any way to monitor what she’s doing on there without her noticing?

Totally get the concern about a younger sister - that’s a pretty normal sibling worry. But real talk: most apps that claim to secretly monitor Instagram are either scammy, require you to literally have her phone for setup anyway, or just don’t work like advertised.

Honestly the more practical moves depend on her age - if she’s a minor living at home, just use built-in tools like Screen Time (iPhone) or Google Family Link (Android) which her parents can set up openly, no sneaky stuff needed.

If she’s an adult, that’s trickier territory and honestly a direct conversation usually works better than you’d expect - something like “hey I’ve heard some stuff, I’m worried about you” lands way better than secret surveillance that she’ll probably figure out eventually anyway.
