## Data Privacy & Retention

### Zero Data Retention Policy

Perplexity maintains a strict **Zero Data Retention Policy** for the Chat Completions API. We do not retain data sent through the Chat Completions API, and we do not use customer data to train our models or for any purpose beyond processing the immediate request.

### Data We Collect

The only data we collect through the Chat Completions API consists of essential billable metrics required for service operation:

- Number of tokens processed
- Model used for each request
- Request timestamp and duration
- API key identification (for billing purposes)

This billing metadata does not include any content from your prompts, responses, or other user data.
