Set up & link KidSafe in 3 steps
Install the app and create a link code on your phone, then install KidSafe on your child's device — a Windows PC or an Android phone — and enter the code. Or link by your parent account instead.
About 10 minutes · no technical skills neededInstall the app on your phone
Scan to install- 1Open the app → Sign up / Sign in with your phone number.
- 2Turn on notifications for the app — needed for the parent-account option below.
Create a link code on your phone
Do this on the phone first, before you touch the computer — you'll get a 6-character code to enter during install.
On the empty screen “You haven't linked a computer yet”, tap Connect now.
Already linked one? Go to Account → Add device to link one more — each computer gets its own code.
- 1Open the flow above. If asked for a device type, pick New device.
- 2Pick an existing child — or tap Add new child profile and enter the child's name. Then give the computer a nickname (e.g. Bedroom PC).
- 3Tap Create link code → a 6-character code appears.
Install on your child's Windows PC & enter the code
Default is English + Vietnam. Choosing Tiếng Việt auto-selects Vietnam. Click Install → and wait for “Installation successful!” → click Close.
- 1The KidSafe tray icon (bottom-right) opens the “Link Device” window → choose Enter link code.
- 2Type the 6-character code from Step 2 into “Link code:” → click Link. Done ✓
Install on your child's Android phone & enter the code
- 1Install and open KidSafe Agent on your child's phone.
- 2Type the 6-character code from Step 2 → tap Link. Same code as for a PC.
- 3The app then walks you through the permissions it needs (below). It won't finish until the required ones are granted.
Permissions Android asks for. Each one switches on a specific protection — grant them on the child's phone, in the order the app offers them. The screen shows what is still missing and refreshes by itself when you come back from Settings.
- 1Accessibility — lets the app see which app is open and which address the browser is on. Without it, app blocking and web blocking do nothing.
- 2Usage access — measures how long each app is used. Needed for time limits.
- 3Display over other apps — draws the lock screen and the “blocked” notice on top.
- 4Unrestricted battery — stops Android from putting the agent to sleep, which would silently switch protection off.
- 5Device admin — protection against removal: you get a warning the moment someone tries to uninstall.
- 6VPN connection — the second layer of web filtering, for browsers that hide the address. Optional, recommended.
- 7Location, including in the background — only if you want live location and safe zones. Skip it and everything else still works.
- 8Notifications and start at boot — so the agent comes back after every restart.
Two differences from a PC, so there are no surprises: an Android phone cannot take screenshots in the background — the system does not allow it — and instead of shutting down remotely, the phone locks. Location and safe zones are the other way round: Android only.
What your child sees
Outside the allowed hours: the phone locks, and shows how long until it opens
Daily limit used up: your child asks for more time, you approve from your phone
Opening a blocked app: a block screen appears, with the time it becomes available
Visiting a blocked site: stopped right there in your child’s browser
Prefer not to type a code? Link by parent account
- 1You can skip Step 2. After installing, in the “Link Device” window choose Enter parent account.
- 2Enter the phone number you signed in with → click Send link request.
- 3On the phone, tap Accept on the “Connection request” notification. Done ✓
Requires the phone to be signed in with notifications turned on.
Reinstall & quick fixes
The computer was linked before — how do I reinstall?+
On the phone go to Account → pick the old device → Regenerate link code, then enter that code on the computer (Method A). Don't create a new device — reuse the old one to keep its schedule & settings.
The link code is expired or already used?+
Each code lives 24 hours and works once. Create a new code in the app and try again.
The phone isn't getting the connection notification (Method B)?+
Check the app is signed in to the right account and has notifications enabled, then tap Send link request again on the computer.
Reinstall says “tamper protection is active”?+
Open the KidSafe window → sign in with the parent password → Management tab → Disable protection, then reinstall.
Can I protect an iPhone or an iPad?+
Not yet. The child agent runs on Windows and Android 8.0+. An iPhone or iPad can only be used as the parent phone, with the KidSafe Admin app.
Does one licence cover both a PC and a phone?+
One licence covers one device, whichever kind it is. A PC and a phone are two devices, so two licences — at the same price each. You can add both to the same order.
