Understanding the Problem

What is DNS?

DNS (Domain Name System) is like a phone book for the internet. When you visit a website, your device asks a DNS server "what's the IP address for google.com?" Your ISP's DNS server sees every single one of these requests—and knows exactly which sites you're visiting.

Why It Matters

Your ISP uses this data to create a complete profile of your browsing habits. They sell this information to advertisers, data brokers, and other companies. Even "private browsing" mode doesn't hide this—your ISP still sees everything.

How Harbor Privacy Works

Harbor Privacy encrypts your DNS requests and resolves them through Unbound, a recursive DNS resolver. Your ISP can see that you're using encrypted DNS, but cannot see which websites you visit. The requests never pass through your ISP's servers.

What is Unbound?

Unbound is open-source software that acts as your own recursive DNS resolver. Instead of asking your ISP's servers where websites are located, Unbound asks the internet's root nameservers directly. Everything stays encrypted, nothing is logged.

Stop your ISP from tracking your browsing

Harbor Privacy sets up encrypted DNS on every device in your home in 60 seconds. No subscriptions. No complications. Just privacy.
