Disable Internet Access

Does this app require Internet access to function properly ? What are the features that require Internet to work ?

Hi, the app can work completely offline.
The app needs connectivity only for some features - pair tracking, smart light integrations (communicating with the hub), Spotify and online radio (Lullabies + Alarms), IFTTT, online services (Google Fit, S Health, Health Connect), and cloud backup (SleepCloud, DropBox, Drive).
But all those features are optional.

Many thanks for the quick reply
