How it works

Everything ChildSafe does, in the order you’ll meet it

Plain English first; the technical detail is tucked inside each section if you want it. ChildSafe runs on the child’s Android phone (8.0 or newer) and is managed entirely from yours.

Setup

Ten minutes with a QR code

Install the ChildSafe parent app on your phone, add your child, and pick an age mode — Young Child, Pre-teen or Teen. A short wizard sets the first screen-time rules, then shows you a QR code. Factory-reset the child’s phone, scan the code, and the phone sets itself up as a managed device. From that point, every rule lives in your pocket.

  • Three age modes — the starting rules match the child, not a one-size default
  • Guided wizard — child’s name, mode, first schedule, done
  • Step-by-step setup guide with photos of every screen you’ll see (follow it here)
  • Change everything later — nothing you choose at setup is fixed
The detail, if you want it

ChildSafe uses Android’s built-in enterprise management (the same framework businesses use to secure staff phones). During QR provisioning, Google’s Android Device Policy takes ownership of the device and force-installs ChildSafe — which is why a child cannot uninstall it. Works on any Android 8.0+ phone; the QR code can be regenerated from the parent app at any time.

Apps

You decide what’s on the phone

ChildSafe works on approval, not blocklists: everything is off until you allow it. For younger children the Play Store is closed entirely. Teens can browse it — but installing means asking first.

  • App requests — your child asks from their phone, you get a notification, you tap approve or reject from wherever you are
  • Play Store control — hidden completely, limited to approved apps, or open with per-app requests, depending on mode
  • Pre-installed apps hidden until you approve them — a new phone starts calm, not crowded
  • Full app inventory — see everything installed on the phone, always
  • Blocking is real — a blocked app is removed or disabled at system level, not hidden behind a PIN
The detail, if you want it

Young Child and Pre-teen modes run the Play Store in whitelist mode (only approved apps are even visible); Teen mode runs it in blacklist mode with the request flow. Blocked apps are uninstalled where possible; system apps that can’t be removed are disabled instead. A background service also watches for new installs in real time, and ChildSafe automatically detects which phone, messages and camera apps your child’s particular phone uses (Samsung, Pixel and others differ) so the essentials keep working.

Screen time

Time that fits your family

Set a daily allowance and the hours it applies — different on school days and weekends. When time is up, the phone locks and your child cannot work around it. Calls and text messages always keep working, so they can reach you and you can reach them.

  • Daily quotas from 15 minutes to 8 hours, with separate school-day and weekend schedules
  • Bedtime that crosses midnight — a 9pm–7am lockdown just works
  • School blocks — only the apps you’ve marked “allowed during school” are available; everything else waits
  • Take a Break — give the scrolling apps a shared hourly budget: “TikTok, Instagram and Snapchat — 15 minutes an hour between them.” When it’s spent, they’re paused until the next hour
  • Per-app usage — see exactly which apps take the time
  • They see their own clock — remaining time is shown on the child’s phone, so the timer is the villain, not you
The detail, if you want it

Enforcement is local to the phone — lockouts land in milliseconds, not on the next server sync, and they keep working with no internet connection. You can set multiple time windows per day (7–9am and 4–6pm, say). During lockdown the phone and messaging apps stay available; everything else is locked at system level. Take a Break budgets are enforced on the device and reset on the clock hour.

Content

The internet, filtered before it arrives

Filtering happens at the network level of the phone itself, so it covers every app and every browser — not just Chrome. It’s on from the phone’s very first boot, and it can’t be switched off from the child’s side.

  • Adult content blocked automatically, everywhere on the phone
  • SafeSearch enforced on Google, Bing and other search engines; YouTube restricted mode enforced
  • 25+ optional categories — gambling, dating, violence and more, each a switch
  • Block whole platforms by name — TikTok, Instagram, Snapchat, Discord and more with one toggle. The block sits on the device, so it holds even where a platform’s own age check wouldn’t
  • Your own list — add any website; use the domain checker to test whether a site is blocked, allowed, and why
  • One-tap internet pause — all children, or one at a time. Dinner is quiet in seconds
The detail, if you want it

ChildSafe enforces encrypted, filtered DNS (via AdGuard DNS, one policy per child) at operating-system level, applied from first boot. The usual ways round a filter are closed: private browsing is disabled in the managed browser, sideloading and unknown sources are blocked (so a VPN app can’t just be installed), Android’s “Circle to Search” screen-search is blocked on newer phones, and Bluetooth file sharing is disabled so content can’t arrive by side door.

Monitoring

Monitoring — only if you switch it on

Every monitoring feature is off by default and separately switchable. Some families want all of it, some none; most start small and adjust. Whatever you enable, your child can see ChildSafe on the phone — this is protection, not spying.

  • Call log — who calls, who’s called, how long
  • Text messages — review SMS conversations for concerning patterns
  • App notifications — see the messages that arrive through WhatsApp and other apps’ notifications
  • Keyword alerts — 16,000+ terms across 13 categories (bullying, grooming, self-harm, drugs, eating disorders, radicalisation and more), updated weekly, plus your own custom words. Critical matches push to your phone instantly, with a context snippet
  • AI-checked alerts — before an alert interrupts your day, AI checks whether it’s genuinely concerning or just song lyrics. If that check ever fails, the alert still comes through — it fails safe, never silent
  • Browsing activity — which sites the phone visited, at the domain level only. Deliberately not a keystroke log
  • Image safety — the phone itself checks new photos (camera, WhatsApp, screenshots, downloads) for nudity and blurs harmful images. No photo ever leaves the device
  • Google account watch — an alert if a new Google account appears on the phone
The detail, if you want it

Monitored texts and notifications are deleted from ChildSafe’s systems automatically after seven days — this is a smoke alarm, not an archive. Keyword scanning happens on the device against a curated database maintained by an automated research pipeline and reviewed continuously; alert levels are configurable per category, and evaluation takes your child’s age mode into account. Image scanning runs a nudity-detection model entirely on the phone, with a sensitivity level you control. Browsing logs come from the DNS filter (domains only — never full pages or content) and are retained by AdGuard for up to 90 days.

Out & about

Where they are, without ringing every five minutes

A quiet look at the map when you want reassurance — no ping on their phone, no fuss. And when a phone goes missing down the back of a sofa or on a bus, you have real options.

  • Live location on a map in the parent app, with accuracy shown in metres
  • Saved places — add school, home, grandma’s; get an alert when they arrive or leave
  • Last known location even when the phone is off or offline
  • Battery level and charging status — so you know “phone dead” from “ignoring you”
  • Lost phone? Make it ring loudly even on silent, lock it with a message on the screen, or — if it’s truly gone — wipe it remotely
The detail, if you want it

Location updates with every device check-in. Only the most recent position is kept on ChildSafe’s servers — each update overwrites the last, so there is no movement history to leak. Arrive/leave alerts are worked out server-side from the places you save, and lost-phone commands are pushed with maximum priority so they land in seconds.

Tamper-proof

They can’t just switch it off

Sooner or later most children try a YouTube tutorial on beating parental controls. ChildSafe is built into Android’s own management layer, not bolted on top — so the usual tricks don’t work, and the unusual ones tell you they were tried.

  • Cannot be uninstalled by the child — it’s enforced by the phone’s own management system
  • Factory reset protection — a reset locks the phone and notifies you immediately; you approve re-setup or block the device
  • Safe mode removed — not guarded, gone
  • Clock tricks detected — date, time and timezone are set automatically and changes are flagged
  • Sideloading and USB file transfer blocked — apps can’t arrive by side door
  • Integrity checked on every sync — the phone proves it’s untampered, using Google’s own verification
  • Everything is logged — tamper attempts go into a permanent safety log you can read in the app
The detail, if you want it

Developer options are disabled at policy level, which on managed Android removes safe mode entirely. Google Play Integrity verification runs on every check-in to detect rooting or tampering. Wi-Fi networks can be parent-managed, and if your child signs into Chrome or adds a Google account, you can control and see that too. The safety audit log is immutable — it survives deletions.

Flexibility

When the rules need to bend a bit

Homework over-runs. There’s a video call with grandparents. Real life doesn’t fit neatly inside Bedtime mode — and rigid controls create arguments. ChildSafe builds the exceptions in.

  • Emergency unlock — your child asks from the locked phone, with a reason. You approve or deny from yours, and the phone unlocks within seconds — for however long you choose
  • Phone and texts always work during any lockdown
  • Take a Break budgets reset every hour — a pause, never a cliff edge
  • Every rule adjustable from your pocket — loosen things for the holidays in a minute
9
Family

The whole family, one dashboard

Parenting is rarely a one-person job. Invite a partner, co-parent or trusted family member by email and share the picture — everyone sees the same dashboard and gets the same alerts.

  • Invite by email — invitations expire after 7 days if unused
  • Full or limited access — grandma can see without being able to change
  • Revoke any time — the primary parent stays in charge

AI

AI on the phone — on your terms

Two optional helpers, both off until you decide otherwise. One is for your child; one is for you.

  • AI Learning Buddy (for them) — a tutor that guides children to answers instead of handing them over, and won’t write homework or essays. Age-tuned for 5–8, 9–12 and 13–17; every message moderated in both directions; concerning conversations flagged to you with the reason; daily message limits you set; on or off per child
  • ChildSafe Assistant (for you) — tell it what you want in plain English: “no TikTok after seven on school nights.” It works out the settings and shows you exactly what it plans to change. Nothing happens until you confirm
The detail, if you want it

Learning Buddy messages pass two independent moderation checks on the way in and the way out, and flagged exchanges appear in your app with context. The Assistant can only reach a fixed set of safe actions — there is no way for it to delete data or remove protection, and every change is confirmed by you before it’s applied.

Growing up

Designed to do less over time

A five-year-old with a phone needs a different thing to a fifteen-year-old with a phone. ChildSafe has three modes — Young Child, Pre-teen and Teen — and you move through them at your child’s pace. The blocks ease, the conversations get harder, and by the time ChildSafe comes off, your child has had years of practice with the phone — not all of it landing at sixteen.

  • Young Child — a handful of apps on a simplified launcher, no Play Store, no open internet
  • Pre-teen — approved apps, family time limits, filtering everywhere
  • Teen — most of the internet with the rails still up, and an app-request flow that teaches asking
