I could also get more info from your habits and you home type and quality from the thermostat. All at your convenience. I didn’t have to ask for permission to any private information. Just by the oven app alone I would have clues about your personal life-

I would now know about how far you are from home

That you are not home

That there’s no one home or that you don’t trust the people you live with to start the oven

How much you spend on utilities

What’s the average temperature you cook food at

How long you cook

How often you cook

Which part of the oven/stove you use most often

Where your home is located

How often you entertain

Where’s your favorite grocery store

When you start cooking

The fact that you are at the grocery buying food to cook that night and how often you do that
