To achieve system-wide DNS filtering, CodaDNS uses Android's VpnService API to create a local virtual network interface that intercepts only DNS queries (UDP port 53). All intercepted DNS queries are forwarded to our DNS-over-HTTPS (DoH) server at https://dns.codadns.com using an encrypted HTTPS connection (TLS). No user internet traffic (HTTP, HTTPS, or any other protocol) is tunneled or routed through this VPN interface — only DNS packets are intercepted and proxied. This is the standard approach used by all system-wide DNS filtering apps on Android (NextDNS, AdGuard DNS, etc.) and is required solely to provide parental control and content filtering features without requiring root access. Technical details: • VPN interface: local address 10.0.0.2/24 • DNS server: 10.0.0.1 (local fake DNS) • Route: only 10.0.0.1/32 — no internet traffic is affected • All DNS queries forwarded via HTTPS/TLS to dns.codadns.com • No data logging beyond your own account's query history DATA & PRIVACY • DNS query logs are stored for 1 day (Free) or 30 days (Pro/Family) • No personal browsing data is sold or shared with third parties • All communication between the app and our servers is encrypted (HTTPS/TLS) • Privacy Policy: https://codadns.com/privacy PLANS • Free: 1 device, basic filtering, 1-day logs • Pro ($2/month or $20/year): 5 devices, 30-day logs, detailed analytics • Family ($5/month or $40/year): unlimited devices, parental controls, child profiles, 30-day logs REQUIREMENTS • Android 8.0 (API 26) or higher • Active internet connection • CodaDNS account (free sign-up at codadns.com)
