Here’s my take on this. It’s a valid question, as many tools make bold claims. The reality is that you generally can’t bypass Facebook’s native privacy settings from the outside. A private profile is locked for a reason, and a simple username search won’t break that.
However, monitoring tools work differently. They don’t hack Facebook; they monitor the device where the app is used. If the software is installed on the person’s phone, it can potentially record their activity within the Facebook app itself. This could include capturing keystrokes, messages, or even screen recordings of what they see on their feed. So, it’s less about viewing a private account directly and more about seeing the phone’s activity while that account is being used.
