Self-Hosted Privacy
Phoenix, when self-hosted, is fully private. No data from your traces, evaluations, datasets, or any other application data is ever sent to Arize or any third party. All of your data remains entirely within your own infrastructure. This means you have complete control over:- Where your data is stored
- Who has access to your data
- How long your data is retained
- Your compliance with data privacy regulations
Telemetry
What kind of telemetry does Phoenix collect?
By default, Phoenix collects basic web analytics (e.g., page views, UI interactions) to help us understand how the product is used. None of your trace data, evaluation results, or any sensitive information is ever collected. The telemetry is limited to understanding how users interact with the Phoenix web interface.Why does Phoenix collect telemetry?
Telemetry helps us to:- Understand how Phoenix is used and improve the most relevant features
- Track overall usage for internal and external (e.g., fundraising) reporting
- Identify and fix issues in the user interface
How can I opt-out?
To disable telemetry, set the following environment variable:Air-gapped deployments
If you are running Phoenix in an air-gapped environment, setPHOENIX_ALLOW_EXTERNAL_RESOURCES=false. This will:
- Automatically disable all telemetry
- Disable external Google Fonts (the UI will fall back to system fonts)
