What do you want to be safe from? That's a rather elaborate set of measures to be posting on here.
A VPN is only as safe as they claim it is. I wouldn't be surprised if many of them are gaily handing over whatever info The Man wants.
That's important. Most VPNs, especially the free ones, can track your activity anyway, it's just that they're tracking you instead of whatever website you're on. There are a few anonymous ones which are paid but I find it hard to trust some VPNs because they might have control over information.
