Are vpn(virtual private network) safe?

VPN is used across the world for many purposes like unlocking websites , keeping your IP private in an online world. VPNs essentially create a data tunnel between your local network and an exit node in another location, which could be thousands of miles away, making it seem as if you’re in another place. This benefit allows online freedom, or the ability to access your favorite apps and websites while on the go. If your smartphone's Wi-Fi is enabled at all times, your device could be vulnerable without you ever knowing it. Everyday activities like online shopping, banking and browsing can expose your information, making you vulnerable to cybercrime. But, the question is are they safe? the paid VPNs are quit safe and they protect you from hackers and offer a lots of other facilities but we have to worry about the free ones. Be aware, that free VPN services might not provide the same type of browsing privacy that pay services offer. Free VPNs have to make money somehow. They might do this by tracking and collecting your browsing data and selling it to third parties, like advertisers. Others might hit you with a steady stream of online ads. Free VPNs might be easier on your wallet, but using one might compromise some of your privacy. So, be careful about your privacy. Use free VPNs only if they are safe. Good Bye.....
