Firebase Crashlytics is a crash reporter for mobile apps, part of Google's Firebase platform. It supports iOS, Android, Flutter and Unity. Crashes with a common failure point are grouped into issues, and realtime alerts report new, regressed or growing issues. Crashes can be linked to Google Analytics events and exported to BigQuery or Cloud Logging. Crashlytics is delivered as an SDK added to the app, with issues viewed in the Firebase console.
Crashlytics is provided by Google, a US company, and is therefore subject to US jurisdiction, including the CLOUD Act. According to Google's Firebase privacy documentation, Crashlytics is a global service that may process data at any Google data-centre location, and the page does not name an EU-specific region for it. Customers are generally the data controller and Google the processor, and Google LLC participates in the EU-U.S. Data Privacy Framework. Crashlytics is closed-source and available only as a service hosted by Google.
