See Who's Watching You Online
SilverArrow shows you the hidden connections between websites, trackers, and the companies behind them.
One shield, four platforms.
SilverArrow blocks the hidden tools that follow you online. It removes tracking codes from links, stops sneaky cookies that don't go away when you clear your history, and hides your device from fingerprinting scripts. You don't need to understand any of it — it just works in the background.
You can get SilverArrow as a Chrome extension, an iPhone app with a Safari extension, an Android app with a Firefox extension, or its own standalone desktop browser for Windows and Mac. Every version shares the same privacy engine — about 330,000 rules working together to block trackers.
Tracking URL wiping
Removes the hidden codes in links that companies use to follow you from site to site.
Super-cookie blocking
Stops trackers that survive a normal cache clear and quietly mark your browser again.
Fingerprint defense
Makes your device look like everyone else's, so trackers can't single you out.
