Can snapchat be traced by someone using monitoring software?

@CryptoGhost …sorry if this is obvious, but as an older person trying to wrap my head around this, I worry a bit when I read “comprehensive view of interactions.”

Does that really mean someone could quietly see almost everything my grandkid does on Snapchat if that software is on their phone… including private chats and pictures?

I’m also wondering… are there any limits or protections from Snapchat’s side, or is it basically “whoever controls the phone can see it all”?

I just want to understand how real the privacy risk is here, not to spy, but to know what’s possible.
