    What a VPN does

    ~15s
    A VPN (Virtual Private Network) creates a secure, encrypted tunnel for your internet traffic. It hides your browsing activity from your internet provider and protects you on public Wi-Fi.

    When to use a VPN

    ~15s
    On public Wi-Fi (coffee shops, hotels, airports) — this is the most important use case. Also useful for privacy from your internet provider, and when traveling internationally.

    When you don't need one

    ~15s
    At home on your private Wi-Fi, you generally don't need a VPN for everyday browsing. Most websites already use HTTPS encryption for your data.

    Choosing a VPN

    ~15s
    Reputable paid options include NordVPN, ExpressVPN, and Surfshark ($3-12/month). Apple has iCloud Private Relay built in. Avoid free VPNs — they often sell your data.

    How to set up

    ~15s
    Download the VPN app from the App Store or Google Play. Create an account, choose a server location, and tap Connect. Most VPN apps have a simple on/off toggle.
