Acutis Firewall

Acutis Firewall is an Android content-filtering application intended for parental control. It blocks access to adult material and to sites its filtering rules classify as dangerous. Filtering is described as taking place on the device itself, meaning traffic is evaluated locally rather than being routed through an external filtering service.

The listing does not state how the filtering rules are obtained or updated, whether categories can be adjusted, or how the configuration is protected from changes by the device's user — all of which matter for a parental-control tool and should be checked against the current release. As an on-device filter it also acts only on the device where it is installed, and not on other equipment sharing the same network.

The application is published by phasnox under the MIT licence. It is available for Android only.
