Out Now!

Tired of being followed around by the same retargeted ads on various websites?
iAntiSpy blocks the trackers that tell advertisers where you've been, so there's nothing to retarget you with.
Frustrated by a simple news site taking ages to load?
Pages arrive without dozens of ad and tracking scripts. Pages load faster and use less data.
Worried about your browsing habits being collected, collated and resold in bulk?
Collection servers never hear from your Mac or PC in the first place.
