Are there any privacy concerns with using a free VPN from Cloudflare?

Yes, there are potential privacy concerns. While Cloudflare offers privacy features, free VPNs often have limitations and may collect data on your usage. They might display ads or inject trackers into your browsing sessions. It's crucial to review the privacy policy of any free VPN service, including those using Cloudflare, and understand what data they collect and how it's used. Look for VPNs with a no-logs policy.
