Apps Where Strangers Can Contact Children - UK Parents' Reference

The single most common safeguarding question we are asked by UK parents is some version of "could a stranger reach my child on this app?" The honest answer is that on most popular apps the answer is yes, by design - the platforms grow by helping people find each other. Whether that becomes a problem depends on settings, on the child's age and experience, and on how openly you have talked about it as a family.

The apps in the table below are the ones in our library where stranger-contact or grooming has been flagged as a primary risk - either because the app is built around meeting new people (Yubo, social discovery apps), because random pairing has historically been part of the product (Omegle, VRChat), because the open chat model invites it (Discord, Telegram, Kik), or because the platform combines public profiles with private messages aimed at children (Roblox, Snapchat, Instagram, TikTok).

A few patterns are worth understanding. Most contact does not start with a hostile or obvious approach. It starts through a shared interest - a game, a fandom, a hashtag, a challenge. The contact often escalates across platforms; an offender will move a child from a public space to a private one, then to an encrypted one, then to images. This is well-documented in NCA and IWF reports and is part of why platform-by-platform settings matter less than how children understand what they are being asked.

Five practical takeaways:

• Private accounts are the foundation. Every app on this list supports a private profile of some kind. Set this first.
• Restrict DMs to known contacts. Strangers messaging directly is the most common pathway in - close it off where you can.
• Teach the "move us to" pattern. Anyone asking your child to switch to a different app or platform should be discussed with you first.
• Children must know they can come back. If they make a mistake or feel uncomfortable, the goal is they tell you - not that the app is taken away as a punishment.
• No app is "safe by default" on contact. Settings change. Check them again every few months.

Use the table below to identify which apps in your house need a specific conversation. Our family agreement gives a structured way to write the rules down. The parent journeys include scripts specifically for the "what if a stranger contacts you?" conversation. If a child has been contacted or harmed, the reporting guide walks through the right next steps.

This is a reference, not a ranking. The aim is not to ban apps but to know which ones carry which risk, and to set them up accordingly.
