A No-log VPN can simply be defined as a VPN service provider that does not keep a database or a log of its subscribers’ internet searches and activities are done via the encrypted network of the VPN. If a VPN service says that it’s a no-log one then it means they are saying that they will not keep a record of your internet activity done while using their VPN. If the VPN provider does not keep your internet record, then it also cannot sell it to a third party, which is almost always a risk.
Not every paid VPN is a no-log one, but choosing a no-log one is usually preferred because, hey, you are paying for being totally anonymous on the web and as much as some VPN providers (the ones that keep your activity log) may claim that they will not share your data, you cannot be 100% sure about their claims. This is why a No-log VPN comes with peace of mind that no one is going to snoop on your online activity. While no one can guarantee that your online activity when even using a paid VPN is fully safe from others, a logless VPN is a far better option than a VPN service that keeps users’ records. So, you should always look for this feature when purchasing a VPN.
