FAQ

Questions, answered

The essentials before you download.

How does Multuser reduce fingerprint linkability?
Each profile launches a supported Chromium-family browser with a stable, per-profile identity. Multuser aligns browser, device, language, timezone, screen, hardware and network-facing signals across pages and Web Workers, and protects WebRTC when a proxy is used. No privacy browser can guarantee that every website will treat a session as an ordinary user, so Multuser also includes live consistency diagnostics and closes a protected browser if its fingerprint-control connection fails.
Does it use real Chrome, or a custom browser?
Real Chrome — and optionally Edge, Brave or Opera. It drives the browser you already trust, so sites render exactly as they expect. No custom fork, no emulation.
Which computers does it run on?
macOS (Apple Silicon M1–M4) and Windows 10 / 11 (64-bit). Because the Mac app is not signed by Apple yet, its first installation needs one Terminal command after dragging it into Applications: sudo xattr -rd com.apple.quarantine /Applications/Multuser.app. The Download page shows the complete steps. Normal in-app updates do not require Terminal. Windows uses its normal setup wizard.
Can my team share profiles safely?
Yes. Cookie sync lets you save a logged-in session on one computer and load it on another, so teammates share the session, not the password. Role-based access means each teammate only sees the groups you give them. Live usage status shows who has a profile open and disables a second launch until that session closes.
Where is my data stored?
Profiles run on your Mac; your account keeps the profile records so they follow you between machines. Proxy logins and 2FA seeds stay hidden from teammates who don't need them, and a profile listed for sale is frozen so its cookies can't be quietly copied.
How does Marketplace buyer protection work?
After a workspace is delivered, the order shows a visible inspection deadline. You can confirm delivery early or open a structured dispute before the deadline; while a dispute is open, escrow remains paused. If no dispute is opened, escrow releases automatically when the inspection window ends. Refunds apply to eligible defects after automated diagnostics or Marketplace review—they are not unconditional.
How much does it cost?
Current plans and prices are shown in the Pricing section above. Choose the profile capacity and billing term that fit your workspace.
