I wasn’t going to upgrade to professional mode, but I think it worked.

As far as I know, professional mode can be paid. I can’t afford the cost, so I want to cancel it, but I don’t know how. Could you show me how to cancel it?

Hey,
When you first log in, you are getting a 7-day pro-membership trial.
When the trial ends, it returns to Free mode automatically.
We don’t have your payment details at this point. You won’t be charged unless you actively upgrade your account.
