The free version is not a very good VPN, I wouldnt trust it for anything actually sensitive. It requires way too many permissions and tracks way too much. It's essentially just an ad for the paid version. But if you're going to pay for a VPN there are way better paid options out there. But really you should never need to pay for a VPN subscription. There are so many other free ways to protect your privacy that don't track your usage or ask for so many permissions.
