Yes, the app supports and works with the parental controls on Nintendo Switch™. Only Nintendo Switch™ profiles that meet the age requirement of 13+ may download and access the Funimation Switch app.
Additionally, parents can control access to mature-rated content. By default, mature content is restricted and not viewable at all on the Funimation Switch app. To allow access to mature-rated content, parents can log in to their Funimation account at www.funimation.com, go to Account > Preferences > Video Settings, and set the Restrict Mature Content setting to “Off”.
