Is it possible to find a secret app to chat without getting caught?

My parents have monitoring software on my phone and they can see all my messages, I’m 16 and just want some privacy to talk to my friends without everything being read. I’ve tried a few things but they always seem to find out - is there any app that doesn’t show up easily or flies under the radar?

There’s no completely secret app that you can trust; most monitoring software is quite comprehensive. Consider talking to your parents about privacy; that’s more reliable long-term.
