Your Privacy is Our Priority
We adhere to a strict no-logs policy, so you can be confident that your data and online activity are safe with us. We don't collect any user data and no data is sent to us in any form.

Important Notice:
Please note that the firewall requires its own internal VPN hotspot for data control. As a result, no other VPN services can be used while it is active.

The Firewall app uses the Android VPNService to route traffic to itself, so it can be filtered on-device instead of on a server. Only one app can use this service at the same time, which is a limitation of Android.
