Reshape what the algorithms believe about you.

It's the idea that you should have a say in how algorithms see you. Right now, platforms build a profile of your interests and behavior, then use it to decide what you see. MirrorMask lets you actively reshape that profile instead of just accepting whatever they've decided you are.

It's how platforms like Google, YouTube, and Facebook decide what content to show you based on what they think you're interested in. MirrorMask changes the signals those algorithms rely on, so you get to influence what shows up in your feeds instead of leaving it entirely up to them.

MirrorMask runs entirely on your Mac. All browsing data (your baseline profile, browsing history, and persona activity) stays on your machine. The only server communication is license key activation and anonymous usage analytics via TelemetryDeck, a privacy-first analytics tool that collects no personal data. No tracking, no advertising, no data sold.

MirrorMask browses websites normally in its own private browser, the same way you would. It performs Google searches, watches YouTube videos, and visits websites. There's nothing that distinguishes this activity from regular browsing.

Ad platforms build your profile based on what you search, watch, and visit. MirrorMask does those things as someone else: a Fisherman, an Investor, a Pet Lover. Over time, the algorithms update their model of you to reflect the persona's interests.

These platforms already have years of data about you. MirrorMask doesn't add to that pile. It corrupts it. Every session buries your real interests under persona activity, making the existing profile less accurate over time. The goal isn't to hide from data collection. It's to make what they've collected less useful. Think of it like flooding a surveillance camera with noise, rather than trying to avoid it entirely.

Ad blockers reduce future data collection. They can't undo years of behavioral history platforms already hold on you. MirrorMask corrupts the existing profile so what they've already built becomes less accurate and less useful. The two work well together.

A VPN hides your IP address. It doesn't change what Google, Facebook, or Amazon think you're interested in. They track you by your logged-in account, not your location. Your profile follows you regardless of which network you're on. MirrorMask runs entirely on your Mac. No traffic is routed through our servers.

Your Mac needs to be awake for MirrorMask to run. If your Mac is asleep at the scheduled time, MirrorMask will run the session when it next wakes up.

No. MirrorMask brings its own private browser, set up automatically the first time you run it. You don't need Chrome, and your everyday browser is never touched. Google is the primary target because its ad ecosystem is the most pervasive and responsive to browsing behavior.
