Porn blocker for Android

Block porn on Android, from a filter to a full lockdown.

Three levels. You choose how hard getting out should be.

Why it needs more than a filter

On Android, anyone can switch off Private DNS or install a VPN in about a minute. So the filter is only the start.

A family filter, for everyone.

Paste one address into Private DNS. Adult sites are blocked in every app and browser, and the app checks it’s really working.

Guard mode keeps risky apps shut.

The apps you pick stay closed during your hard hours, and VPNs and bypass browsers stay closed all the time. It only knows which app opened, never what’s on screen.

Lockdown shuts the way out.

It locks the settings people use to get around a filter. Setting it up takes a reset phone or a computer, and the app walks you through it.

The usual ways around it

Whichever level you’re on, lowering protection, leaving lockdown and making a new unlock code all wait 24 hours. Going up happens straight away.

See each one, with and without lockdown

Way around it	Without lockdown	With lockdown
Switching Private DNS off	Today notices and walks you through the fix	Locked
A VPN app	Guard mode keeps common ones closed	VPN settings locked, VPN apps paused
Chrome’s own secure DNS	Can skip the filter	Set to use the phone’s DNS
Firefox, Brave, Tor and proxy apps	Guard mode keeps them closed	Paused whenever installed
Guest user or work profile	Possible	Blocked
Safe mode, or uninstalling the app	Possible	Blocked
Changing the clock	Possible	Set automatically

Setting up the filter yourself

Open Network & internet
In Settings. On Samsung phones it’s under Connections, then More connection settings.
Choose Private DNS
Then “Private DNS provider hostname”.
Paste the filter’s address
family-filter-dns.cleanbrowsing.org, then save. VisionShield then checks it’s really working.

You can use this filter without VisionShield if you like. What the app adds is the day’s wait, guard mode, lockdown, and a check that notices when the filter’s been switched off.

Questions

Does it work in Chrome on Android?

Yes. Private DNS covers every app, including Chrome. Chrome can use its own secure DNS, which skips the phone’s; lockdown mode sets Chrome, Edge and Samsung Internet to use the phone’s DNS, with SafeSearch and private browsing off.

Does VisionShield use a VPN?

No. It uses Android’s Private DNS setting, so there’s no VPN slowing the phone or draining the battery, and nothing reads your traffic.

Does guard mode read my screen?

No. Guard mode is only told the name of the app that opens, so it can close the ones you picked at hard hours. It never reads what’s on screen.

Why does lockdown need a reset phone?

Android only lets an app manage a phone’s settings as its device owner, and it only allows that on a freshly reset phone, or one with no accounts signed in using a computer. The app walks you through it and says plainly what it takes.

Can I get out of lockdown?

Yes. Turning it off, like every change that weakens protection, takes a day, and the unlock code is needed. A lost code can be replaced, and that takes a day too. A factory reset is left as the last way out, on purpose.
