Is my data encrypted on an open WiFi network?

If you are connected to a GOOSE VPN server, the answer is yes.

When you are on an open Wi-Fi network in, for example, a hotel or shop, others who are on the same network can access the data that comes to and from your device in no way. This data is encrypted between the GOOSE VPN server, your device, and vice versa with an encryption key.

So, make sure that you have GOOSE VPN turned on, at least on unknown networks, to make sure that no one can get your digital data.
