YOUR SETUP GUIDES

Follow one path at a time.

Each guide stays on this page, so you can come back if a setting looks different.

Start here on your phone

Put Gaurd on the router

While connected to home Wi-Fi, choose your router brand below. You will sign in to the router, save two DNS numbers, then test on your phone. This covers devices that use your router's DNS.

Look for Internet, WAN, LAN, DHCP, or DNS Server in your router settings.

Try opening router settings
Router page did not open? Try these addresses
192.168.1.1 192.168.0.1 10.0.0.1

On iPhone, open Settings → Wi-Fi → tap the ⓘ beside your connected network → Router. On Android, open Wi-Fi details for your connected network and look for Gateway or Router. Type that address into your browser. Your internet provider app may also have router settings.

1
Log in to the router The password is often on the router sticker, in your internet provider app, or with whoever set up the Wi-Fi. If none of these pages opens, find the router address in your Wi-Fi details.
2
Find DNS settings Look for words like Internet, WAN, LAN, DHCP, DNS Server, or Advanced. If there is an Automatic DNS switch, turn it off.
3
Type these two numbers Put Primary DNS in the first box and Secondary DNS in the second box. Save or Apply when done.
Primary DNS
1.1.1.3
Secondary DNS
1.0.0.3
4
Check for IPv6 DNS boxes If IPv6 DNS is available, set these too. Otherwise some devices may use an unfiltered IPv6 connection. If the router has IPv6 but no DNS controls, ask your provider or router maker how to set family DNS for IPv6.
IPv6 Primary
2606:4700:4700::1113
IPv6 Secondary
2606:4700:4700::1003
5
Reconnect and test After saving, wait two minutes. Turn Wi-Fi off and on again on a phone, then run these checks while the phone is on home Wi-Fi.
Check Cloudflare Open this first. It should show Cloudflare DNS. This alone does not prove adult filtering. Test malware block This Cloudflare test page should be blocked. Test adult block This Cloudflare test page should be blocked.

How to know the home setup worked

On a phone connected to your home Wi-Fi, check all of these:

  • A normal website opens.
  • The adult-category and malware test links above do not open.
  • Repeat the checks on each device you want covered. A router setting does not protect a phone on mobile data.
If the tests do not block: make sure the phone is on home Wi-Fi, turn Wi-Fi off and on, then try again. If it still does not work, check both IPv4 and IPv6 DNS, your phone's private DNS or VPN setting, and whether the router lets devices choose their own DNS. Your internet provider may need to help.
No router access needed

Protect a child's phone or tablet

Use the controls built into the child's device. These steps also work away from home. Keep the parent passcode and account with the parent.

iPhone or iPad

Use Apple's Screen Time web-content control.

  1. Open Settings → Screen Time on the child's device.
  2. Turn on Content & Privacy Restrictions.
  3. Open App Store, Media, Web & Games → Web Content and choose Limit Adult Websites. Menu names vary by iOS version.
  4. Set a Screen Time passcode the child does not know. In Family Sharing, manage the child's Screen Time from the parent's device.

Works on mobile data too, but this is a web-content control, not a guarantee for every app.

Check it safely

In Web Content, add example.com under Never Allow. Try opening it in Safari on the child's device. It should be blocked. Then remove example.com from Never Allow and confirm it opens again. This checks that Screen Time is enforced without visiting an adult site.

Android phone or tablet

Use Android Private DNS for family filtering on Wi-Fi and mobile data.

  1. Open Settings → Network & internet → Private DNS. Search Settings for “Private DNS” if the menu differs.
  2. Choose Private DNS provider hostname.
  3. Enter family.cloudflare-dns.com and tap Save.
  4. For a child, also set up Google Family Link on the parent's and child's devices to manage Chrome and app access.

The child may still change Private DNS unless device management prevents it. VPNs and some apps can bypass DNS filtering.

On Android, check that a normal site opens and Cloudflare's safe adult-category test page does not. Repeat on mobile data. On iPhone, use the Screen Time check above; a Cloudflare DNS test does not verify Screen Time.
Optional for computers

Optional: protect a Mac or Windows PC away from home

The router protects home Wi-Fi. This helper also sets family DNS on this computer when it uses other networks.

FAQ

Does Gaurd cost anything?

No. The guide, Cloudflare Family DNS, and the computer downloads are free.

Does Gaurd watch browsing history?

No. Gaurd is not spyware, a VPN, or a monitoring app. It helps set safer DNS defaults.

Will this block everything 100%?

No filter is perfect. DNS filtering blocks a lot, but a VPN or custom DNS can bypass it. Router-level DNS helps cover most home devices.

What does malware-domain protection mean here?

It means the DNS provider blocks many known malware, phishing, and botnet domains used in modern scams. It reduces risk, but it is not a firewall and it doesn’t replace router updates + a strong admin password.

Can I turn it off?

Yes. Open the starter file again, type 2, and press Return/Enter.

Does it block other websites too?

Gaurd uses Cloudflare Family DNS for adult and malware domain filtering. It does not add unrelated website blocks.

Why do I need the router step?

The computer helper only changes that computer. The router step is what makes phones, tablets, TVs, and guests on home Wi-Fi use the safer family DNS.

Why do I need a desktop helper at all?

Websites are not allowed to change your DNS/router settings (security restrictions). A desktop helper can request admin permission and apply settings safely.
