Trying to insure subscription cancelled – DU Recorder - Screen Recorder Review

I just started the 7 day FREE TRIAL, 10 Minutes ago, 01/10/2021 12:35pm CST(USA) and now I want to insure II have cancelled it effective 01/10/2021 12:47pm cst (USA). Please reply with confirmation. This app is not what I was looking for. I’m sure it performance well with the features it promotes. I just didn’t read the description well enough to see that it wouldn’t allow me to use it as a video recorder. I do not see this app listed among my Apple subscriptions so I can’t cancel there and I do not see an email to contact the developer. I want written confirmation that I will NOT be charged for this app.
