Likely they want detailed user data and what devices you use, and they want to cross reference that with geolocation so they can upsell you stuff.

I would say it’s likely they’ll start serving ads in the app and “recommending” you other services or things like a subscription. Any app that you have to look at will get ads these days, just look at Uber.

This is why I bought IKEA bulbs that are dumb. I avoid anything that uses an app, because it will update itself to make a new thing sell better.
