Lark requests access to your smartphone data in Apple Health or Google Fit in order to give you the best possible experience with Lark.
Lark uses this data to provide coaching to you on your daily updates. You can also see your data trends over time from the Data tab within the Lark app.
We encourage you to grant Lark permissions to all available data sources in order to provide the best experience possible. However, please do what is most comfortable for you.
