FAQ
Does this test my VPN connection?
No. It is a local planning calculator only. Use official VPN app tests, DNS leak checks and provider documentation to verify behavior.
Should I enter hotel Wi-Fi passwords here?
No. Do not enter network passwords, account logins, IP addresses or private work details.
Can a VPN bypass every captive portal?
No. Many captive portals require a browser login before the VPN can connect. Confirm the official app behavior and keep a fallback network available.
