MirrorMask for Mac

MirrorMask is a native macos app that gives you control over your algorithmic profile. It scrapes your real Google ad profile to show you every interest, demographic, and signal that advertisers have on you. Then, using handcrafted personas, it browses the web as someone else — automatically, every night while you sleep.

Features

• Baseline profile capture showing what Google thinks you are
• 10 built-in browsing personas (each with search queries, Youtube interests, websites, Facebook pages, and Reddit subs)
• Daily automated browsing sessions on a configurable schedule
• Before-and-after profile comparison
• Detailed run history
• Menu bar integration

MirrorMask runs 100% locally — all data stays on your Mac. The only server communication is license key activation. No analytics, no telemetry, no tracking. Built with Swift for Apple silicon and Intel macs.
