Is this a reliable VPN service?

I’ve been searching through VPN services for various reasons, and I was wondering if www.hideipvpn.com/ is reliable. It has good reviews on sites and such and I was just wondering if anyone here had used them before.

One thing that caused me to ask this question was what I found in the privacy policy: “However, we cannot guarantee that the information submitted to, maintained on, or transmitted from our systems will be completely secure.”

If you know what this means, please expand more on this as I do not know what to think about it.
