We want you to remain anonymous. All. The. Way. So when you sign up for our VPN, we don't ask for any personal information – no username, no password, no e-mail. Instead, you get a so-called "numbered account" which is randomly generated.

As for paying anonymously, cash is still king.

Q: Can I really pay with cash?
A: You bet, and please! Just put your cash and payment token (randomly generated on our website) in an envelope and send it to us. We accept the following currencies: EUR, USD, GBP, SEK, DKK, NOK, CHF, CAD, AUD, NZD.

For your right to privacy,
