FCS Quantix DNS Firewall

FCS Quantix DNS Firewall blocks ads, trackers, malware, and adult content across every app on your phone — not just your browser. All filtering happens directly on your device. Nothing about your browsing is ever sent to our servers, because we don't have any.

WHAT IT DOES
- Blocks advertising and tracking domains before they ever load
- Stops known malware and phishing sites
- Optional adult-content filtering you can turn on
- Works system-wide — every app, every browser
- Speeds up browsing and saves data by cutting out ad traffic

PRIVATE BY DESIGN
- All filtering runs on your device — no cloud, no accounts, no login
- We collect nothing: no browsing history, no analytics, no telemetry, no ads
- Your query log and statistics never leave your phone
- Open about exactly what the app does — read our privacy policy

SIMPLE TO USE
- One tap to turn protection on or off
- Toggle categories: Ads & Trackers, Malware & Phishing, Adult Content
- See live statistics: how much has been blocked
- Review a local log of recent activity
- Allowlist any domain you want to let through

HOW IT WORKS
Quantix uses Android's VPN feature to filter DNS requests locally on your device. It is NOT a traditional VPN — your traffic is not routed through any external server. Only DNS lookups are processed, and only while protection is active. Allowed lookups are resolved securely over encrypted DNS-over-HTTPS through the provider you choose (Cloudflare, Quad9, or your own).
