The negative here is their being based in the United States, but they do a hell of a job in making it near impossible to get you. Full excerpt from torrent freak earlier this year:
Private Internet Access
1. We absolutely do not maintain any VPN logs of any kind. We utilize shared IP addresses rather than dynamic or static IPs, so it is not possible to match a user to an external IP. These are some of the many solutions we have implemented to enable the strongest levels of anonymity amongst VPN services.
2. Our company currently operates out of the United States with gigabit gateways in the US, Canada, Germany, France, UK, Switzerland, Sweden, the Netherlands and Romania. We chose the US, since it is one of the few countries without a mandatory data retention law. We will not share any information with third parties without a valid court order. With that said, it is impossible to match a user to any activity on our system since we utilize shared IPs and maintain absolutely no logs.
3. We are in compliance with DMCA as all companies, world-wide, must be. We have proprietary technology and an experienced legal team which allows us to comply without any risk to our users.
4. We accept many payment methods directly, including PayPal, CC, Google, Amazon, Bitcoin, Liberty Reserve, OKPay, and CashU. Further, we would like to encourage our users to use an anonymous e-mail and pay with Bitcoins to ensure even higher levels of anonymity should it be required. We only store the minimal information required to provide customers refunds.
