Does a weather app need my precise location to give an accurate forecast?

Generally no. Forecast models produce values for grid areas measured in kilometres, so a city or postcode resolves to the same forecast that GPS coordinates would. Precise location can improve radar and severe-weather alerts, but it is not universal even in this category: two of the five apps compared here decline location access entirely, and one declares only approximate location.

Why do weather apps share so much more than apps in other categories?

Location paired with a device identifier is exactly the combination the advertising market values, and most weather apps are free. The declarations reflect that: this is the category where entries most often list location and identifiers under shared rather than only collected. It is not uniform, though — the grid below also contains apps that declare no sharing at all.

Weather apps

Google Play shows a data-safety declaration one app at a time. Here are 5 weather apps side by side, so the differences are visible rather than remembered. Categories none of them declares are hidden.

Weather is the original trade of location for a free service, and location is the load-bearing row on this page. It is also the row that makes this category unlike the others here: sharing data with third parties is uncommon across most of this dataset, and weather apps account for a large share of the sharing that does appear — location included. Worth knowing, though, is that the trade is not inherent to forecasting. Some apps below declare no location collection at all, which is possible because a forecast needs a place rather than a person, and models resolve to areas measured in kilometres. Where an app declares precise location, the useful question is what the extra resolution is for.
