Betternet VPN has faced scrutiny regarding its logging practices. While it claims to have a no-logs policy, it does collect some connection logs, including the user's IP address, duration of the session, and the amount of data transferred. These logs are said to be used for troubleshooting and optimizing the service. However, this logging practice has raised concerns about user privacy, as it goes against the principle of complete anonymity. Users seeking a VPN service with strict no-logs policies may need to consider alternative providers.
