This open-source app was first written around 2018.

The application does not allow data/wifi connection to stay active for more than a fixed number of minutes ( 1 to 600 ) that the user has set.

It has been rewritten a few times to accommodate many Android restrictions that have been added to newer Android systems.

A rooted device is necessary to shut down your data connection.

It also requires a service that monitors the state of your data connection, manages timers, and issues disconnects if the data connection state changes the timer will be reset, for example, if I set my timer to 4 min and then I turn off my data connection when the connection is available again the 4 minutes timer will restart ensuring that data can only be connected for 4 minutes.

## Use-cases

- Privacy (only allow data connection enabled for a few minutes when you need, and then the phone will always disconnect from networks after that time. If you have a VPN on your home Wifi, you might want to leave the Wi-Fi network on.

- Conserve Battery. If you don't use your Phone very often, there's no reason to have any network-enabled features
