Terms of use — short version

Please keep the attribution line under the widget. It is the only thing we ask in return.
You may restyle the attribution line to match your site, and you may change the wording.
The widget runs entirely in your visitor's browser. We never store their IP address or their generated passwords.
We may change how a widget looks. The URLs on this page will keep working.

Technical notes

Each widget is a standalone page served from unblockmaster.com and loaded in an iframe, so it cannot read or change anything on your page. It ships its own small stylesheet and no third-party scripts or trackers.

If you leave "auto-fit height" enabled, the snippet also loads a ~1 KB script that listens for a postMessage from the widget and resizes the iframe to match its content. Without it, the iframe keeps the fixed height in the snippet — which is fine, the heights we suggest fit every result state.

The widgets are available in every language this site supports. Pick a language above and the snippet points at that version.
