I fully agree with @Jeroen_Somhorst
But my Answer would be:
Simple Answer Yes, everything she knows about you and your life is stored in the database on Homey and at this moment I can’t think of things that I can not get out of the database of Homey.
Use the Athom-Api to get all from Homey (Zones, Devices, Settings, Flows, Alarms, Folders, Insights, etc. etc. )
And what is not stored in the database on her, they (Athom) store it in the cloud and is absolute necessary to function. Your Account, ID of your Homey’s, Your Phones and the Apps you develop. Can’t think of more…
I played with HomeyScript or the New Api playground (https://developer.athom.com/tools/api-playground) and I can’t think of anything that I can’t access from the API, most things can be changed with the Api if it is logical to change. They prevent changing most things that would break Homeys functioning.
The only thing I don’t know what they collect and store: Number of Devices (fe a KAKU or Zigbee Device) or Services Connected (How many users use Google Home, Alexa, Spotify ) for making Services better…
(11) For business intelligence and marketing
…installed devices, structure of the home and aggegrated user data. Note that all data used for this goal is pseudonymized before analysis.
