What Acutis Firewall is
Acutis Firewall is a free parental-control app for Android that helps parents limit children’s online access. It blocks adult content, malware, phishing sites, gambling and social media across apps, rather than only inside browsers. Parents can set daily screen-time limits and schedule blocking for periods such as homework or bedtime. A PIN can protect settings from being changed or disabled. Filtering runs on the device through Android’s VPN Service API, which intercepts DNS requests and checks domains against configured blocklists. The app downloads blocklists from StevenBlack/hosts and URLhaus, while permitted DNS requests are forwarded to Cloudflare’s public resolver at 1.1.1.1. Its privacy policy says it does not collect, store or transmit personal information, browsing history, device identifiers, location data, analytics or other data to external servers. Blocklists, rules, settings and an optional PIN remain local and are deleted when the app is uninstalled. The Android project is published under the MIT License.
