cloak

Chrome privacy extension: block selected trackers, clean tracking links, reduce fingerprinting, and protect shopping sessions.

Cloak is a privacy extension for desktop Chrome that makes everyday browsing harder to profile. Start with a full 7-day trial—no card, account, email, or automatic charge. Use Cloak while shopping, comparing prices, booking travel, creating accounts, and making decisions involving your money or identity. WHAT CLOAK DOES • Blocks selected third-party tracker and ad-tech requests • Removes common UTM and other tracking parameters from links • Reduces selected canvas, WebGL, referrer, and browser-recognition signals • Sends Global Privacy Control (GPC) and Do Not Track (DNT) signals • Isolates selected shopping-session state with per-site cookie and storage cleanup • Warns about browser-visible urgency, scarcity, and personalization signals • Shows a local privacy receipt explaining what Cloak changed • Offers optional checkout email sub-addressing using an address you provide PRIVATE BY DESIGN Cloak's protection assessment and receipts stay local to your browser. The extension does not sell browsing data, use it for advertising, or transmit your browsing history for analytics. AFTER THE TRIAL The local trial ends after seven days and does not become a subscription automatically. If you choose to continue, Cloak costs $30 for six months. Purchase through cloak.build, then activate inside the extension using your checkout email and activation code. IMPORTANT LIMITS Cloak is not a VPN, antivirus product, complete ad blocker, anonymity guarantee, or promise of lower prices. It blocks selected trackers and ad-tech requests rather than every advertisement. Some websites may require per-site compatibility adjustments, and email sub-addressing depends on merchant support. Desktop Chrome only. Learn more at cloak.build.
