Privacy & VPN Basics
Guides on VPN protocols, leak protection and staying private and secure online.
Why These Basics Matter
Without a VPN, your ISP can see every site you visit, public Wi-Fi can expose your logins, and a single DNS leak can undo everything a VPN promises. The guides below explain the technology in plain language, what protocols like WireGuard actually do, how leaks happen, and how to verify your own setup instead of trusting an app's green tick.

Privacy FAQs
Does a VPN make me anonymous?
No, and anyone claiming otherwise is selling something. A VPN hides your IP from websites and your traffic from your ISP. It does not stop browser fingerprinting, and logged-in accounts still identify you. It is one strong layer, not invisibility.
What is a VPN leak?
When your real IP or DNS requests escape the encrypted tunnel, via DNS, WebRTC or IPv6. You will not notice it without testing, which is why we built a step-by-step leak-check guide.
Is using a VPN legal in India?
Yes. The 2022 CERT-In directions put logging obligations on VPN providers, not users. Using a VPN remains fully legal, details in our dedicated guide.
