Questions
Is Pro a subscription?
No. You pay once and it never expires, so there's nothing to renew or cancel.
How is the payment handled?
Through lava.top, in roubles, dollars or euros. The receipt comes from them.
I paid while signed out. Where is Pro?
Pro is tied to the email you paid with. Sign in or create an account with that email and Pro shows up on it. If you paid with a different address, write to us.
