ELI5: When an app crashes and I send a report, what exactly does that do, and how is it used?
gpt
It tells the developer that the app has crashed, first of all.

But it can also tell the developer what you were doing, what screen you were viewing, what data you were using, what route you took to get to that screen, and so on.

All of this can help fix the bug. Obviously the developer needs to know what screen you're looking at. But it's not uncommon to find find bugs where the app crashes every time you enter a " character, for example. By sending the data to the developer, the developer can look at the report from dozens or even hundreds of similar crashes, and can realise that the " character is the common denominator.

Obviously this has privacy issues - it's up to you to decide whether your privacy is worth sacrificing in order to help make the app better. If you use the app for banking or drug dealing, then probably not. If you use it for looking at pictures of cats you might be happy to share this data.
