If you think about a VPN Service, you need to know, that this kind of service needs an excessive amount of servers, connections and employees. These servers, connections and employees need to be paid somehow. If you dont pay for your service with your dollars, the company behind it needs to collect the money for the business somehow. So what is the only thing they could use to make money? Right! Your Data. So please, if you want to be secure and anonym, don´t use a free VPN. I highly recommend you to use a good quality service like PP. Even though often the free ones promise to be good. But sadly we live in a capitalist world. Everybody needs to make money. Nobody will give this to you as a gift.
