When you turn off a VPN, your internet connection will no longer be encrypted and your web traffic will not be routed through a server in a different location. This means that your web activity will be visible to your Internet Service Provider (ISP) and any websites or servers you access will be able to see your real IP address. This can be a security risk if you were using the VPN to protect your online privacy or to access content that is restricted in your location. It is generally a good idea to keep your VPN turned on when you are connected to the internet to ensure that your online activity is secure and private.
