does phoenix save user data?

Phoenix does not send your traces, evaluations, datasets, or any application data to Arize or third parties when self-hosted; all data remains within your infrastructure, and you control where and how long it is stored. In Phoenix Cloud, your data is stored on US servers by default, and you can self-host Phoenix for full data residency control if needed. Basic web analytics (not trace or evaluation data) are collected by default, but you can opt out via environment variables. For persistent storage, Phoenix supports both SQLite (default, local) and PostgreSQL (recommended for production), and you can configure data retention policies or delete data manually. No user data is sent externally unless you explicitly export or back up traces or datasets yourself.
