Android Privacy Settings: Complete Security Guide 2026

Start with Settings > Google > Manage your Google Account > Data and Privacy. Disable Web and App Activity, which logs every Google search and app interaction. Disable Location History, which creates a detailed map of everywhere you go. Disable YouTube History if you use YouTube. Turn off Ad Personalization in Settings > Google > Ads to reset and disable your advertising ID. These settings reduce Google's data collection significantly but do not eliminate it entirely — some telemetry is collected regardless of settings.

Go to Settings > Privacy > Permission Manager. Review each permission category systematically. Location should be set to While Using App for navigation and weather, and Deny for most other apps. Remove Camera and Microphone access from any app that does not need it. Pay attention to Body Sensors, Nearby Devices, and Phone permissions — these are commonly abused for tracking and fingerprinting. Android 14 and later allow you to grant photo access to specific photos rather than the entire library.

Enable Private DNS in Settings > Network and Internet > Private DNS and set it to a privacy-focused provider like dns.quad9.net or dns.adguard.com. This encrypts your DNS queries and blocks many tracking domains. Disable Wi-Fi scanning and Bluetooth scanning in Settings > Location > Location Services, as these allow location tracking even when Wi-Fi and Bluetooth are turned off. Consider using a VPN that supports Android system-wide routing.

For maximum privacy, GrapheneOS on a Pixel device provides the strongest Android privacy available. It removes Google Play Services entirely and includes hardened security features like a hardened memory allocator, network permission toggle, and sensor permission controls. The trade-off is losing access to some banking apps and Google-dependent services. CalyxOS offers a middle ground with microG compatibility. For most users, a hardened stock Android with the settings in this guide provides a significant privacy improvement without the compatibility costs.
