Mirrormask

Google knows more about you than your therapist, your partner, and your mom combined. They track every search, every video, every click, and they build a profile so detailed it's creepy. Then they auction that profile to advertisers and let the algorithms feed you exactly what they think will make you spend money. MirrorMask says nope—not tonight.

MirrorMask is a native macOS app that takes your real Google ad profile and buries it under layers of fake activity. Every night, automatically, it opens your existing Chrome and browses as someone completely different—a fisherman, a DIYer, a tech nerd. Ten handcrafted personas come included. It searches, watches YouTube, scrolls through Reddit—all as your chosen fake persona. You never type a password. It uses your existing Chrome session. It just searches and watches. No posting, no profile changes, nothing sketchy. And here's the thing: everything stays 100% on your Mac. Built with Swift. Local. Anonymized analytics via TelemetryDeck—no personal data ever leaves your machine.

$39, one time. No subscription. That breaks down to less than your streaming services combined and you actually get something useful back: privacy that doesn't require a VPN, browser switching, or changing how you live online. The concept is simple—if Google's going to build a model of you, build a better model on top of it. Make yourself statistically invisible. Or use it backward—break out of the recommendation loop and train the algorithms to show you what YOU want to see instead of what they think will convert. macOS 14+ required.
