Almost every VPN provider you come across will have some type of claim regarding logs. Offering a logless service is often viewed as a key selling point. Many users look to VPNs as a means to improve privacy and increase anonymity. It makes sense that they don’t simply want to go from ISPs tracking them to another company doing the same.
Although it would be nice and simple if all VPNs simply kept no logs at all, the fact is that many do keep some records. These might include logs of websites visited (these are rare) or usage logs such as time connected to the VPN and the amount of bandwidth used. There are various reasons for keeping logs. For example, bandwidth may be recorded if there is a cap per user per month. In some cases, logs are kept to support to a business model that requires the additional data. For instance, a provider might profit from advertisements placed on commonly visited websites.
