I’ve developed crash reporters for years now. The only way personal information is making its way into crash reports is if the app developers put it there. Otherwise it’s function names, the OS version, binary images that were loaded into the app, the time it happened.

Certain termination reports do contain small memory dumps and/or register values, so theoretically could could contain decodable PII. This is something the OS vendor provides, not the developer of the app or the crash reporter.
