Android firewall: The Android app can block apps from connecting over Wi-Fi or mobile data and offers app-specific firewall rules.
Blocklists: The service offers more than 190 predefined blocklists across parental, security, and privacy categories.
Encrypted DNS: RethinkDNS says its resolver responds over TLS, and its site describes DNS over HTTPS and DNS over TLS support.
Censorship circumvention: The Android app encrypts DNS requests to help prevent censorship through DNS manipulation.
Traffic monitoring: The Android app shows per-app connection activity and data use, with reports that flag known or suspicious connections.

Privacy: The privacy policy says the Android app does not collect, sell, license, or share data, and that the F-Droid build has no trackers, ads, spyware, or loggers.
