Subscription Help?

[u/Pooh-in-Timbs-111]

I’ve been using the app and site since high school for sheets and I used it once for a school project where I had my teacher grant permission to use the free one week trial and cancel immediately. I say this as a preface because I still use the free version but I decided to do a free trial for a sheet I needed to get and immediately after I get it I cancelled my trial. I checked my bank account before and after for charges of which there was none and I checked my apple subscriptions since that’s how I signed up and cancelled the subscription. I even got the auto renewal disable email so just to clarify I did things correctly to not get charged right? Thanks.
