The one with the blue icon has a site at Windy.app. Their privacy policy is much more hand-wavy, with lines about how they “don’t sell” but “share” your personal information:

One of the techniques they list explicitly is to use the Meta pixel for targeted advertising. I’m not aware of any way to remove geo data from, for example, the Meta pixel and the auctions it sells into. It suggests to me that perhaps they’re thinking of your geo data as incidental to placing targeted advertising.
What a terrible take. People like apps, we should make apps private I stead of telling people not to use apps. FWIW, websites can gain access to your location too, so plenty of people will still be tracked.
