What is a VPN?
A VPN (virtual private network) encrypts your internet traffic and routes it through a server in a location you choose. Your real IP address stays hidden, and the network you're on: your ISP, a hotel, an office: sees only encrypted data going to one server.
How does a VPN work?
Encrypt
The VPN app encrypts everything your device sends before it leaves.
Tunnel
Traffic travels to a VPN server in the country you picked.
Exit
Websites see the server's IP and location, not yours.
What does a VPN hide, and from whom?
What can't a VPN do?
An honest list, because "military-grade everything" marketing helps no one:
- It can't make you anonymous to services you sign in to: your account identifies you.
- It can't block cookies or browser fingerprinting: that's your browser's job.
- It can't protect a device that already has malware on it.
- Most VPNs can't even connect on networks that filter VPN protocols: hotels, offices, campuses.
How is OmnixVPN different?
That last limitation is the one OmnixVPN was built to fix: it tunnels over QUIC on port 443, the same protocol and port as the web, so it connects onnetworks that block other VPNs. And instead of one location for everything, it giveseach app its own exit country: simultaneously.
Frequently asked questions
What is a VPN in simple terms?
A VPN is an app that creates an encrypted connection between your device and a server elsewhere, then sends your internet traffic through it. Websites see the server's location instead of yours, and networks you're on can't read your traffic.
Is using a VPN legal?
In most countries, yes. VPNs are legal and widely used for privacy and remote work. A few countries restrict or regulate them, so check local law when you travel. Illegal activity remains illegal with or without a VPN.
Can I be tracked if I use a VPN?
A VPN hides your IP address and encrypts traffic on the network, which blocks the most common tracking. It does not stop cookies, browser fingerprinting, or the accounts you sign in to: those identify you regardless of IP.
Does a VPN hide my activity from the Wi-Fi owner?
Yes. On hotel, café, office, or campus Wi-Fi, the network operator sees only encrypted traffic to one server: not the sites you visit. That is one of the strongest everyday reasons to use one.
Do I need a VPN at home?
It depends on your goals. At home a VPN mainly hides your browsing from your ISP and lets you appear in another country. On networks you don't control: travel, work, public Wi-Fi: the case is much stronger.
