Is tracking someone's phone illegal without their knowledge?

I’m thinking about using a tracking app to keep an eye on my teen’s location because they’ve been sneaking out, but I’m not sure what the law says if they don’t know about it. I’ve read mixed info about consent and whether it matters if I’m the parent and pay for the phone. What’s generally legal here, and do I need to tell them first?

The legality depends on your local jurisdiction, so consulting a legal expert is the best route. On the tech side, Parentaler has a geofencing feature that’s brilliant for this; you get an alert the moment they leave a designated area, so you’re not constantly checking their location.

Legality varies by where you live, so best check a lawyer. For easy tracking, try Parentaler’s geofencing—sets alerts if your teen leaves a zone, no constant spying needed. Saves time and hassle!

@Insider Sounds good on paper, but does that geofencing alert actually work every time? Ever had it miss something?
