If you are looking for the best VPN client, you should primarily be focused on privacy and anonymity, of course. However, while most VPNs prevent third parties from collecting your data, some providers store information about their users.
Logging and privacy policies vary from one provider to the next. That’s why our reviews examined each provider’s policies on data collection. Some states have laws that require VPN providers to gather some amount of user data if they wish to operate or promote their product in those countries. However, many trusted VPN providers try to avoid those states and look to take their business elsewhere. Others work around local regulations. They claim that they do not collect any data on their users and therefore cannot know what countries their users operate from.
Some of the data that might be stored includes bandwidth usage and connection logs. This isn’t considered especially problematic since the information is primarily used by providers to improve the service or for bandwidth-based paid plans. However, some of the cheapest VPN providers collect IP and traffic logs, which endanger your anonymity. Any VPN that collects that kind of data should be avoided.
