Most browsers compete on what they add. Null competes on what it removes. Blocking isn't an extension you bolt on — it's the foundation: ads, trackers, cookie walls & phishing stopped on your device before they load. No cloud, no server, no account — your data's journey is device → nowhere. The ∅ shield counts what didn't load, emptied ad slots get stamped "∅ hidden by Null," and unblockable video ads are auto-skipped. Free for Windows.
