We don't lock any features behind a paywall. The only difference between a Free account and Paid account is that Free users have a limit on how much tunnelling they can do a month, and Paid users do not. As for the charge you received, we do NOT charge that much for any of our subscriptions, we also do not collect or sell user data. It sounds like the email you have received may be some type of phishing attempt. I suggest you do not select anything in that email, and instead reach out to support at https://help.tunnelbear.com/hc/en-us - they can help confirm if there were any payments made, and answer any questions.
