am I the only person that puts a "cancel free trial for XYZ" in my calendar the minute I sign up for anything? So much so, I have an "Add expiration reminder"

am I the only person that puts a "cancel free trial for XYZ" in my calendar the minute I sign up for anything? So much so, I have an "Add expiration reminder" iOS shortcut. Pretty sure I downloaded it from the Shortcuts gallery or something, it doesn't look like something I'd write.
