The air pollution data that you collect using Flow is stored on your device until a connection with Flow’s companion application is established. Then the data is transferred to the app for you to view. The app also uses your data to give you advice on how to avoid air pollution.
When your app is active and your phone is connected to the internet, your data is synced with our system. This means the raw data in your app is scrubbed of any personal information before being transferred to our environmental data platform and removed from your phone to free up storage.
