How to Block App Tracking with Alternative DNS Servers for Better Privacy
Many apps track user activity without consent. Security experts recommend switching to alternative DNS servers like DNSForge to block trackers system-wide on Android and iOS devices.
Many mobile apps integrate third-party modules that collect usage data. This practice, known as tracking, becomes particularly problematic when personal information is involved or when data collection occurs without user consent.
Advanced users often rely on specialized apps that filter all data traffic locally on their smartphones. However, for everyday users, a simpler and more convenient solution exists: changing the DNS server settings on the device. According to IT security researcher Mike Kuketz, this method effectively blocks trackers system-wide.
Alternative DNS servers prevent tracking
The Domain Name System (DNS) acts as the Internet’s directory, translating human-readable web addresses into numerical IP addresses. Every time a user connects to a website or service, a DNS query is made to resolve the address.
Alternative DNS operators, such as Dnsforge.de, go beyond standard resolution. They identify and block requests to known tracking services, preventing apps and browsers from sending data to third parties. This means that not only app traffic but also general web browsing is shielded from unwanted surveillance.
How to change the DNS server on Android and iOS
Security researcher Kuketz recommends the donation-financed Dnsforge.de as a trustworthy public DNS provider. Setting it up is straightforward:
- On Android: Open “Settings > Network & Internet > Private DNS”. Select “Hostname of the provider of the private DNS”, enter dnsforge.de, and save.
- On iOS: Visit the Dnsforge.de website in Safari. Scroll to the “iOS” section and tap “dnsforge.de (DoT)” next to “Normal” to download the configuration profile. Follow the five on-screen steps to activate the profile.
Why this matters
Changing DNS settings is a simple yet effective way to enhance privacy. Unlike ad-blockers or VPNs, DNS-based filtering works at the system level, covering all apps and browsers. While it does not replace comprehensive security measures, it significantly reduces exposure to trackers and unwanted advertising networks.
As mobile devices continue to play a central role in daily life, adopting such measures ensures that users retain greater control over their personal data. For those seeking a balance between convenience and privacy, alternative DNS servers provide a practical solution.
