Pi-hole Telemetry & AI Blocklists

A curated collection of telemetry-focused DNS blocklists for use with Pi-hole.

The goal of this repository is not to "break the internet", but to reduce unnecessary telemetry, analytics, ACR (automatic content recognition), and tracking traffic from major platforms (Big Tech, Smart TVs, AI services) while keeping core functionality intact wherever possible.

What this repo is (and isn’t)

✅ This repo is

• A set of plain-domain blocklists suitable for Pi-hole Blocklists
• Focused on telemetry, analytics, ads, and tracking
• Safe to host publicly (GitHub raw URLs)

❌ This repo is not

• A "block everything from X" mega list
• A guarantee of zero telemetry (DNS blocking has limits)
• A replacement for OS/app privacy settings
