Common questions.
Does GuardianBlock work on Windows 10?
No. GuardianBlock runs on Windows 11 Home or Pro, 64-bit (x64). Windows 10 and earlier are outside its scope.
Can I use it on a laptop I also use for work?
A personally owned, unmanaged PC that you also use for work qualifies when setup finds no device management or policy conflicts. A PC your employer, school, or IT department manages is out of scope.
Does it change my DNS, VPN, or firewall?
GuardianBlock works inside Windows and your browsers. It does not alter DNS, VPN, firewall, proxy, or network-drive settings.
How many computers can I protect?
Up to three of your own Windows 11 devices on one subscription. Retiring a device frees its slot for another.
Does it work on my phone?
No. GuardianBlock is Windows software and there is no mobile app.
