3. Third-party services

We use Google/Firebase services (e.g., Firebase Authentication, Analytics, Crashlytics, Cloud Messaging) to authenticate users, analyze usage, and report crashes. These services may process device data and identifiers under their own policies.

You can review how Google handles data at policies.google.com/privacy.
