How do I cancel an account? Developer Please Read – PokeArt - TCG Card Maker Review

So I accidentally created an account and I don’t know whether it’s gonna show all my cards I created, or just the cards I submitted. I just want to know because I have parental restrictions on the guidelines page, so I can’t view it. Thank you
