Using BRUTAL Optimizer offline: what works without internet

BRUTAL Optimizer does almost all of its work locally on your PC. After you have activated once, you can use the app on a machine with no internet connection. This page lays out exactly which features need a connection and which keep working offline.

How your license behaves offline

After your first activation, the app stores your last-known license locally. When the license server can't be reached, that cached license keeps Pro features working through an offline grace window — you'll see the Offline badge state instead of Pro. When you reconnect, the app re-verifies and switches back to the normal Pro badge automatically.

Offline is a state, not an error. An "Offline" badge means the app is running on your cached license because it couldn't reach the server. That's expected on a disconnected PC. If you stay offline past the grace window, Pro features pause until the app can re-verify — reconnect and it sorts itself out. For what the various "couldn't reach the server" messages mean, see why a check couldn't complete.

What needs internet

These features have to reach a server, so they won't work offline:

What works fully offline

Everything that acts on your own PC keeps working with no connection:

Plan your online steps for when you have a connection. Activate, check for updates, and run the network lab tests while online, then take the app offline for the local optimization work.

FAQ

QuestionAnswer
Will Pro stop working if I lose internet?No — your cached license keeps Pro features running through the offline grace window. Past that window, Pro pauses until the app can re-verify; just reconnect.
Why does it say "Offline" instead of "Pro"?The app couldn't reach the license server and is running on your last-known license. It returns to Pro after it re-verifies online.
Can I activate a new install with no internet?No. First activation needs a one-time connection to the license server. After that the app runs offline.

FAQ

Will Pro stop working if I lose internet?

No. After activation, your cached last-known license keeps Pro features running through an offline grace window (the "Offline" badge). If you stay offline past that window, Pro pauses until the app can re-verify your license — just reconnect and it switches back automatically.

Why does the badge say "Offline" instead of "Pro"?

The app couldn't reach the license server, so it's running on your last-known license. It returns to the normal Pro badge once it re-verifies online. See /support/couldnt-check-explained for what these messages mean.

Can I activate a new install without internet?

No. Your first activation (free or Pro) needs a one-time connection to the license server. After that initial activation, the app runs offline.
