Online activity logs may include users’ IP addresses, browsing history, metadata and connection times. Users should be wary of VPNs that track and record this kind of data, which is a serious privacy violation.
VPNs collecting online activity logs claim to do so to limit the number of devices using one subscription account. This is fair enough, but this situation contradicts VPN providers’ stance of keeping users anonymous with free, no-logs services. Most VPNs notorious for collecting users’ online activity logs are free services that need to generate revenue through ads or other means in the absence of a paid subscription.
The only way users can be assured that the VPNs are secure and don’t keep online activity logs is by using reputable VPN providers. Even then, users should be cautious, as most VPNs keep tabs on user information to some extent.
