Parents' guide — No-go areas

What is a no-go area, and when should a parent use one? (2026)

A no-go area is a place you mark on the map so you are told the moment your child goes there, the opposite of a safe zone. This guide explains what it is, when it is worth using, how to set one up on Android and iPhone, and what the free tools and Safeinest can and cannot do. It stays honest about the limits, including the one iPhone condition that trips people up.

What a no-go area is

A no-go area is a place you mark on the map so you get an alert if your child goes there. It is the opposite of a safe zone. A safe zone tells you when your child arrives at or leaves a good place, like home or school. A no-go area tells you the moment they enter a place you would rather they stayed away from.

You draw a small circle around the spot on the map in the app. You give it a name. From then on, if your child's phone crosses into that circle, your phone gets a message. That is the whole idea. It is a quiet safety net, not a wall. It cannot physically stop a child going anywhere. It can only tell you early.

The short answer

Use a no-go area for one clear, specific place you have a real reason to worry about, and keep the list short. Mark the spot in your family-safety app, give it a plain name, and leave the rest of the map alone, so the alert still means something when it comes.

When should a parent use one

A no-go area works best for a single place with a real risk, not for a general worry. Good reasons to set one:

• A dangerous spot nearby, such as a canal or river, a building site, a railway line, or a busy main road.
• A place you have already asked your child to stay away from, where you want to know if that is holding.
• A house, shop or street linked to an older group, to bullying, or to trouble your child has had before.
• A part of town that a school, a social worker, or a court has asked a child to avoid.

Keep it to one or two. A map covered in no-go circles sends so many alerts that you stop reading them, and an alert you ignore protects nobody. If raising this with your child feels hard, how to talk about location sharing covers how to do it without it feeling like spying.

Step by step

The exact words on screen change between phones and app versions, but the path is almost always the same: open the map, choose to add a place, and mark it as a no-go area rather than a safe one.

On Android and iPhone, in the Safeinest parent app:

1. Open Safeinest and tap the map, or Places.
2. Choose Add a place, then pick No-go area, not Safe zone.
3. Search the address, or drag the pin to the exact spot.
4. Make the circle as small as the place allows. A tight circle around one house is better than a wide one that covers half the street.
5. Give it a plain name you will understand in a hurry, like "the canal", not "Zone 3".
6. Save. The alert is now live.

One honest point about iPhone. On an iPhone, location alerts only work if your child's phone has location set to "Always" for the app. If it is set to "While Using", the alert will not fire when the app is in the background, which is most of the time. You set this once, together, in the iPhone's Settings under the app's name. On Android, the background location setting does the same job.

What the free tools do, and where they stop

Apple's Find My is free on every iPhone and shares location through Family Sharing. It can notify you when a family member arrives at or leaves a place. It is built around places you want them to be. It has no real "warn me if they enter here" feature, and it carries no screen-time rules.

Google Family Link is free for Android children and shows a supervised child's location next to its app and screen-time controls, but it does not offer no-go-area alerts at all. Our fuller look at it is in how to use Google Family Link, and where it stops.

Both tools are good at the safe-zone half of the job and silent on the no-go half. If a place you want your child to avoid is the thing keeping you up at night, the free tools will not cover it.

Where Safeinest helps, and where it cannot

Safeinest is a family-safety app made by a UK team. No-go areas work on both Android and iPhone, with the one iPhone condition above: location must be set to "Always". The rest of the location features, including live location, a 24-hour trail, safe zones, and "tell me if they don't arrive" arrival alerts, also work on both phones. Family voice calls, messages and an SOS button work on both too.

What differs by phone is detection and control, not the map:

The honest limits: Safeinest shows where a phone is, not where a child is, and a phone that is off, flat, or left behind simply stops reporting. On an iPhone, no app can read iMessage or WhatsApp, and no app can stop a child deleting it. That is Apple's rule, not a Safeinest choice. You can see the full list of what works on each phone on the features page.

The numbers

Phones reach children early now. Ofcom's 2025 research found that 56% of UK 10-year-olds and 83% of 11-year-olds own a smartphone, and that 99% of 8 to 17-year-olds are online. So the question for most parents is not whether a child has a phone, but how to keep a light hand on where it goes.

It matters which phone that is. World Population Review, using StatCounter data, reports that outside a handful of countries most children carry an Android, about 94% in Pakistan and 96% in India. That is why message-safety alerts, which only Android allows, reach so many families, while on iPhone the location tools do the heavy lifting.

And children often do not tell us when something goes wrong. LGfL research, reported through Internet Matters, found that when something bad happens online, 2 in 5 children never told anyone. A quiet alert is sometimes how a parent finds out at all.

What to say to your child

Keep it short and honest. You could try: "I've marked one place on the map, the canal, because it isn't safe, and I'll get a message if you go there. It isn't about catching you out. It's the same as me saying, please don't play near the water." Show them the app on their own phone, so nothing is hidden. A child who knows the rule can keep it; a secret one just learns to hide. If you want a calmer version of this chat, our guide to SOS and emergency contacts pairs well with it.

Helplines

If your child needs to talk, or you do, these UK lines are free and confidential: Childline on 0800 1111, and the NSPCC on 0808 800 5000. In an emergency, or if you believe your child is in danger, call 999. You do not have to wait to report a child missing. Outside the UK, call your local emergency number or your country's child helpline.
