How Nautillo Detects Invisible Trackers

Trackers are small pieces of code or images that follow you around online. They can be:

• Ad trackers – used by advertisers to build a profile of you.
• Analytics trackers – measure what you do on a site, even after you leave it.
• Invisible pixels / images – tiny, invisible images that quietly “report back” about your activity.

You don’t see them, but they see you.

Nautillo provides online privacy protection by filtering out trackers before they ever load in your browser. Here’s how it works:

• Known tracker list – Nautillo blocks thousands of well-known tracker domains automatically.
• Suspicious behavior detection – Even if a tracker isn’t on the list, Nautillo spots hidden tricks like invisible pixels and blocks them too.
• Privacy Guardian mode – For maximum security, turning on Privacy Guardian blocks even more subtle tracking attempts in scripts, videos, and widgets.

With Nautillo, you control how much protection you want:

• ON → Maximum privacy. Trackers are blocked, but some website features that rely on trackers (like chat widgets or embedded video ads) may not load.
• OFF → Full site experience. Everything works, but trackers are active and your browsing isn’t protected.

It’s your choice: privacy-first browsing or full access with trackers allowed.

Every tracker that slips through makes your online profile bigger. That means:

• More ads that “follow” you around the internet.
• Higher risk of phishing or identity theft.
• Less control over your own data.

By combining phishing protection with tracker blocking, Nautillo helps you stay safe while browsing without slowing down your experience.

Most people don’t realize how many trackers are watching them until they install Nautillo. From the moment you switch it on, you’ll notice fewer distractions, fewer ads, and more peace of mind.
