Protect your kids and family — from harmful websites and apps.
It's 100% free to download.
Nothing about your family's browsing ever leaves your device.
A phone or laptop connected to the internet is part of everyday life now — but it also means your child could stumble onto scam websites, high-risk real-money gaming sites, or sensitive content, or that some other "safety" app quietly collects and stores your family's personal information. Safe World checks every website right there on your own device and blocks the harmful ones automatically — for free, with nothing about your family ever sent anywhere.

DownloadYour family needs protection online — without losing your privacy.
A phone, tablet, or laptop with internet access is part of everyday life now — for school, homework, games, and staying in touch with friends. But that same connection can expose your child to scam websites trying to steal money, high-risk real-money gaming sites, and sensitive content they're too young to see. On top of that, many so-called "safety" apps quietly collect and store everything your family browses, and can even sell or share that information. Your family deserves real protection from harmful websites — without handing your personal data to another company to get it.
Real protection, without the trade-offs.
100% free
Safe World is free to download and free to use, for as long as you need it — no subscription, no trial, no hidden cost.
We never see your family's data
Every decision about what to block happens privately, right there on your own phone or computer. We don't collect your family's browsing activity, and nothing about the sites you visit is ever sent anywhere — not to us, not to anyone.
Open for anyone to check
The list of blocked sites and the code that decides what to block are both public for anyone to look at. You don't have to just take our word for it.
Works on the devices you already use
Chrome, Android, iPhone, Mac, and Windows are all ready today — so wherever your family goes online, Safe World can go too.
Same rules, three on-device engines.
Chrome
Static declarativeNetRequest rulesets, one per category, block or redirect requests before they leave the browser. Toggling a category enables or disables its ruleset — no traffic is inspected by a remote service.
Android
A local VpnService tunnels only the device's DNS traffic — to nowhere but itself. Every query is checked on-device; blocked names get a synthesized NXDOMAIN, everything else is forwarded unmodified to the resolver your device already uses.
iOS
SafeWorldCore compiles your settings into a Safari Content Blocker list, and a packet tunnel filters lookups from every other app. Because iOS names the app behind each packet, whole apps can be blocked too — not just the sites they load.
The same protection, without the middleman.

| Cost | Free and open source | Free tier plus paid plans |
Five platforms, one shared rule set.
The blocklists and the code are the same thing you can read.
Every category — scam, high-risk real-money gaming, sensitive content — is a plain list of domains plus the matching logic that chooses between them, both public on GitHub. Found a site that should, or shouldn't, be listed? Open an issue or a pull request.
