How To Choose the Best VPN for You
A VPN app encrypts your data when you go online. It sends that shielded data to your ISP to make the connection and get you online. The VPN also deciphers your data, so it’s usable wherever you ’re transferring it.
The same goes for data transferred back to you — the VPN encrypts it before it sends.
Without a VPN, when you connect to the internet, your device sends a request to your ISP or a Wi- Fi network. The data that transfers between you and your destination isn't translated. This leaves you vulnerable to anyone who wants to view your online exertion. And your IP could be traced, which could expose your identity.
