It’s only the IP address of your VPN that appears on the internet, and your address is hidden.
VPN also gives different server locations, which means it makes IP addresses from different locations worldwide available.

But with a VPN software in your devices, those things won’t be disclosed to others. Your data will only be stored on the VPN server. VPN providers don’t care about what’s in your server, and they don’t even check it. So they won’t tend to disclose it to anyone. Being anonymous when you go online is a great way of VPN in giving you privacy.
