I understand that the features are optional but the copy reads as stating the app is fun and light and then doesn't go on to list any of the features that make it "fun and light."

There is a colon at the end of the third to last sentence that uses the phrase "fun and light" but then those optional features in the hyphenated list that follows are things that most adults don't generally associate with lightheartedness or fun.

Perhaps you could describe what the light and fun elements of your app are so as to provide contrast to those other optional restrictive and conservative features?
